 The vertical grinding machine is a kind of advanced grinding equipment designed and developed on the basis of the extensive use of advanced technology at home and abroad, combined with many years of various mill machine production experience. It is an ideal equipment for grinding industry, which integrates crushing, drying, grinding and grading transportation. It can be widely used in cement, electric power, metallurgy, chemical industry, nonmetallic mineral industry and so on. It is used to grind lump, granular and powdery raw materials into the required powder materials.

 The main structure of the vertical grinding machine

Vertical grinding machine mainly consists of powder separator, grinding roller device, grinding disc device, the pressure device, reducer, motor, shell and so on. The separator is a highly efficient and energy saving powder separator. Grinding roller is used to crush and crush materials. The millstone is fixed on the output shaft of the reducer and is the place where the grinding roller compacts the material. The pressurizing device is a component for grinding roller to provide enough pressure to crush material.

 Working principle of the vertical grinding machine

When the vertical grinding machine is working normally, the motor drives the grinding disc to rotate through the reducer, and the material falls from the feed inlet to the center of the grinding disc through the lock air feeder. With the rotation of the grinding disc, the material moves to the edge of the grinding disc under the action of the centrifugal force. Through the ring groove on the grinding disc, the material is crushed by the roller rolling. The crushed material is brought up at the edge of the grinding disc by high-speed airflow from the wind ring and the large particles fall directly onto the grinding disc to re-ground. When materials in the air flow pass the upper separator, under the action of rotating rotor, the coarse powder falls from the cone bucket to the grinding disc and is re-ground. The qualified fine powder goes out with the airflow and is collected by the dust collecting device, that is, the product. Materials containing moisture are dried in contact with hot air flow. By adjusting the hot air temperature, it can meet the requirements of different humidity materials and achieve the required product moisture. By adjusting the separator, the required thickness of different products can be achieved.

 Main features of the vertical grinding machine

1.Low investment cost

Due to the integration of crushing, drying, grinding and grading, the system is simple and the layout is compact. The area is about 50% of the ball milling system, and it can be arranged in the open air. Therefore, the investment cost can be reduced greatly.

 2.Low operating cost

(1)High grinding efficiency : using the grinding roller to directly crush the material on the grinding disk, low energy consumption, and 30% ~ 40% less energy consumption than ball grinding system.

(2)Less abrasion: longer service life and less wear due to the fact that the grinding roller does not contact the grinding disc directly during work and that the grinding roller and the lining plate are made of high quality materials.

 3. Strong drying ability

Because the hot air directly contacts with the material in the grinding, it has strong drying ability and saves energy. By adjusting the hot air temperature, it can meet the requirements of different humidity materials.

 4. Easy operation

(1)The system is equipped with automatic control system, which can realize remote control and easy operation.

(2) Vertical grinding machine is equipped with equipment to prevent direct contact between roller sleeve and disc liner to avoid destructive impact and severe vibration.

 5. Stable product quality

Because the material stays in the grinding for a short time, it is easy to detect and control the product granularity and chemical composition, reduce the repeated grinding, and stabilize the product quality.

 6. Convenient maintenance

Overhauling the oil cylinder, turning the rotating arm, replacing the roll sleeve and liner plate is convenient and quick, reducing losses in downtime.

 7. environmental protection

Vibration is small, noise is low, and the whole equipment is sealed, the system works under negative pressure, no dust spillover, clean environment, and meets the national environmental protection requirements.

 The process flow of the vertical grinding machine

According to the location of humidifying tower and dust collector, the vertical grinding machine has two different layout schemes, namely, the three fan system and the double fan system. A cyclone collector is used for the collection of products. This arrangement reduces the working negative pressure of the system and the amount of gas passing through the dust collector. The electric dust collector can also be replaced by the bag dust collector as the final dust collector. The dust collector can be the electric dust collector or the bag collector, and the grinding gas is directly entered into the dust collector. The system reduces the number of equipment and simplifies the system configuration.

 Application field

The size of the R Raymond mill can be adjusted within 80 to 325 mesh range, and some materials can reach up to 600 mesh.

 The Structure of Raymond Mill

 The structure of Raymond mill is mainly composed of the main engine, analyzer, fan, cyclone separator, cyclone separator and air duct. The main engine is composed of frame, intake volute, blade, grinding roller, grinding ring and cover.

 The grinding roller is tightly pressed on the grinding ring under the action of centrifugal force. Therefore, when the grinding roller and grinding ring wear to a certain thickness, the output, and fineness of the finished product will not be affected. The replacement cycle of grinding roller and grinding ring is long so that the disadvantage of short replacement period of wearing parts of centrifugal grinder can be eliminated. The air flow of the machine is circulating in the fan - mill - whirlwind separator - the fan, so it has less dust than the high-speed centrifugal mill has, the operation workshop is cleaner and the environment is less polluted.

 Performance Advantages of the Raymond Mill

 1. Convenient transportation and installation

 Raymond mill, its ingenious structural design, which makes it occupy smaller space, and makes it more convenient in transportation, installation, operation, and maintenance.

 2. High Efficiency and Zero Pollution

 The Raymond mill that is produced by our company uses PLC electric automation control to reduce the failure rate and labor cost of the equipment effectively. Meanwhile, it can help to achieve high and efficient production, and achieve a good production environment with zero noise and zero pollution.

 3. Fineness can be adjusted arbitrarily

 The fineness of the grinding powder of Raymond mill can be adjusted arbitrarily between 80-800 mesh. The applicability is more flexible and extensive. We can see that the GUIKUANG Raymond mill is the best choice for non-metallic ore grinding powder.

 4. Long Period Replacement of the Parts

 The grinding roller and grinding ring of Raymond mill have a longer replacement period, which eliminates the disadvantages of the short replacement period of the fragile parts of the centrifugal grinder

 The Operation principle of Raymond Mill

 When Raymond mill works, the material needs to be added to the feeder from the side of the hood. Raymond machine revolves around the vertical axis by means of the grinding roller device which is hung on the main plum frame. At the same time, it revolves on its own axis. Due to the centrifugal force when rotating, the grinding roller is swinging outwards and tightly pressed to the grinding ring. This enables the scraper to shovel the material to the grinding roller and the grinding ring. Therefore, it can achieve the purpose of crushing material due to the rolling of the roller.

 The Winnowing Selection Process of Raymond Mill

 After the materials being grinned, the fan blows the wind into the main engine shell, blowing up the powder, sorting through the analyzer above the grinding room, passing the rough materials into the grinding room and then regrinding it. The suitable fineness materials go into the cyclone collector by the wind. After collection of these materials, the finished products will be discharged through the powder mouth. The air flow from the upper end of the large cyclone collector will return to the fan. The winding road is cyclic and flowing in the negative pressure. The increasing part of the air volume of the cyclic air road is discharged by the exhaust pipe between the fan and the main engine, then this part enters the small cyclone collector to carry out purification treatment.

Pendulum Grinding Mill

Pendulum mill is also called as suspension roller or Raymond mill. It is a "ring and roller" powder-making mill equipment, which is combined with air flow screening and pneumatic conveying. The pendulum grinding mill belongs to the roundel immovable mill and has high universality. It also has the characteristics of continuous powder making dry-type, the concentration of grain size, continuous fine fineness, compact structure and so on. The particle size of the pendulum grinding mill can be adjusted in the range of 0.125-0.044mm (equivalent to 120-325 mesh) according to different requirements.

 The Application Ranges of the Pendulum Grinding Mill

 The Pendulum Grinding Mill is widely used. Common grinding materials and usage ways are as follows:

Soil types: clay, China clay, bentonite, magnesia, clay, bauxite, etc.

Non-metallic ores: gypsum, talc, graphite, fluorite, calcite, limestone, calcite, barytes, apatite, tabular spar, feldspar, quartz and so on.

Metal oxides: manganese iron ore, chromite, Ilmenite, bauxite and so on.

Chemical compounds: coke, lime coke, smelting coke, barium sulfate and so on.

Others: the products of the pendulum grinding mill can be used in many industries. For example, the metallurgical industry produces the magnesia as the refractory layer of blast furnace; the oil industry uses the barytes powder to seal the injector; some industries produce bentonite powder as the lubricant for drilling; the chemical industry produces different stone powder as the filler in rubber, plastics, paper making and paint; porcelain, glass, enamel, white cement, gypsum and magnesia products are all processed by pendulum grinding mill.

The pendulum grinding mill is mainly used for grinding non-inflammable and explosive mineral materials, Moh’s hardness of which is below 7 level and humidity of which is below 6%.

 Operation Principle of the Pendulum Grinding Mill System

 The bulk material is broken by the Jaw crusher to a certain size (powdery or fine particles can not pass through the Jaw crusher), and the material is conveyed vertically to the hopper by a bucket elevator. Then, the electromagnetic vibration feeder delivers the materials quantitatively, evenly and continuously into the main machine for grinding. The pulverized fines are carried out by the blower’s airflow and graded by an analytical machine placed above the main engine. Suitable fine powder that meets the requirements will be entered into the large cyclone separator with the air flow. After separation, the powder will be discharged through the discharge pipe, that is a qualified product. The air flow enters the blower by the return duct at the upper end of the cyclone separator. The whole airflow system is closed loop and operates under negative pressure. Because the grinding material contains moisture, when milling the moisture will evaporate into gas. That gas then leaks in each connection of the whole pipe, which makes an increase in the volume of air in the circulating air stream.

 This increased air volume will be introduced into the small cyclone separator from the air duct between the blower and the main engine. The fine powder with the air flow is collected by the small cyclone separator. Then it will be discharged by another outlet pipe. The gas will be discharged into the atmosphere through the exhaust pipe of the upper end of the small cyclone separator.

  The micro powder mill is a highly efficient flour milling equipment, which was made on the basis of high-pressure powder mill and was improved by fineness classification technology. The advanced fineness classification technology of Germany and Japan adopts the principle of fluid mechanics. Scientists studied diligently with a quiet mind, and then they designed a new micro powder mill. So they solve the problem of high cost successfully. It is a high-efficiency and high-pressure micro powder mill.

 The Application Scopes of Micro Powder Mill

 The micro powder mill is mainly suitable for grinding of conventional materials and the ultra-fine powder processing of non inflammable and non explosive materials, such as kaolin, limestone, calcite, talcum, marble, barite, gypsum, iron oxide red, iron oxide green, aluminum hydroxide, pigment, bentonite, clay, coal, activated carbon and so on, the humidity of which is less than 8%, and the Moh's hardness of which is less than level 6.

 The Structure Characteristics of Micro Powder Mill

 The high-pressure micro powder mill mainly consists of the main engine, blower, superfine analyzer, finished cyclone powder collector, bag filter and connecting duct. According to user needs, it can provide with auxiliary equipment such as the hoist, storage bin, electric cabinet, feeder, crusher and so on. In the grinding mill room, the grinding roller assembly is hung on the grinding cradle through the cross arm shaft. The grinding cradle, spindle and the relieving tool post are fixed. The pressure spring is tightly pressed on the outer end of the cantilever housing of the grinding roller bearing chamber by a tension rod. Taking the transverse load axis as the supporting point, the grinding roller is firmly pressed on the inner surface of the grinding ring by the spring pressure.

 When the motor is rotated through the drive, the blade of the blade is synchronized with the grinding roller, and the roller rolls around the surface of the grinding ring and rotates around itself. The analysis machine drives the rotating of the impeller through the motor drive. The speed adjustment of the analysis machine determines the fineness of the powder. The relieving tool in the relieving tool post and the grinding roller rotate at the same time. Then the grinding roller rotates on the inner surface of the grinding ring and revolves around itself. The analysis machine drives the impeller of the analysis machine through the motor drive device, and the speed adjustment of the analyzer determines the fineness of the powder.

 The Main Features of Micro Powder Mill

 The application scope of the high-pressure powder mill is much larger than that of the airflow mill.

Compared with other mills, the grinding pressure of grinding roller on the material can provide 800---1200Kg under the action of high-pressure spring. It saves energy. Under the same circumstance of output and fineness, the energy consumption of the system is only 1/3 of that of the airflow mill.

The investment is small and the efficiency is high. Under the same circumstance of output and fineness, the price is only 1/8 of the airflow mill.

Compared with the air mill, the production link is less. Firstly the airflow mill must crush the material of 20mm to the superfine powder of 100 mesh, and the high-pressure micro powder mill can make the material reached the average particle size about 6.5 μm to 12.5 μm for one time, of which the size is below the 20mm.

The grinding device adopts overlapping type multiple stage seal and has good sealing performance.

The dust removal effect of the mill can totally reach the national dust emission standard.

 The impact crusher is widely used in various kinds of hard and brittle materials such as rock, abrasive, refractory, cement clinker, quartz stone, iron ore, concrete aggregate and others. It is especially suitable for building the architecture with sand or building the road with sand stone. The impact crusher has a simple structure, low price, smooth operation, high efficiency and energy saving. The impeller and the material in the vortex broken chamber greatly reduced the cost of the wear-out parts and the maintenance work. The impact crusher effectively solved the "iron pollution" in the crushing process of glass and other materials. It also solve the "card" problem in the process of the crushing of steel slag. The ingenious internal airflow’s self circulation eliminates the dust dispersion.  

 The Factors Which Affect The Production Capacity

 Generally speaking, there are many factors affecting the production capacity of the impact crusher. All in all, there are 5 factors. As following, the GUIKUANG machinery will describe these 5 factors and put forward the corresponding solutions.

 1. The hardness of the material: the harder, the more difficult to break up the material and the more serious to wear the equipment. It will slower the speed and lower the ability. So we need to pay attention to the selection of materials.

 2. The composition of the material: before entering the impact crusher, the more fine powder contained in the material, the more crushing. Because the fine powder is easy to adhere to the influence of transportation, the material with fine powder content should be screened in advance. That action will make the fine powder selected out from the material as much as possible so as to avoid the normal work of the impact crusher.

 3. The fineness of the material after crushing process of the impact crusher: the higher standard of the fineness, the smaller the material which is required to be crushed. That is to say, the weaker the crushing capacity. In this aspect, it all depends. There are no special requirements. Generally, we set the fineness of the material to medium and fine.

 4.The viscosity of the material: the stronger the viscosity of the material, the easier to adhere. We can see that the material with large viscosity will adhere to the inner wall of the crushing chamber in the GUIKUANG impact crusher. If we don’t clean it in time, it will affect the working efficiency of the crusher, and may also affect the normal work. Therefore, when choosing materials, we must pay attention to the viscosity of materials to ensure the viscosity is not too strong.

 5. The humidity of the material: when the water content accounts large proportion in the material, the material is easy to adhere to the impact crusher, and it is easy to cause the clogging in the process of feeding the material. It will result in the reduction of the crushing capacity. To solve this problem, the humidity of the material should be strictly controlled when we choose the material. If the humidity of the selected material is too high, we can choose some way to reduce the percentage of it in the material by sunshine or air drying.

 6. The convenient maintenance of the impact crusher

 The main problem which many customers are concerned about is the maintenance. GUIKUANG machinery manufacturers pay special attention to this kind of problem in the production of impact crusher. The impact crusher designed by us is mainly composed of the feeding port, the feeder, the overflow, the impeller, the crushing chamber, the counter attack board, the spindle, the frame, the motor and so on. It has the characteristics of reasonable structure and stable operation. If there is a failure in the operation, the customer can open the observation door to view the internal condition of the equipment and adjust the equipment parts. The technical personnel of our company will teach the customer the basic operation and maintenance skills.If there is a problem that you can't solve, welcome to call our company's after sale telephone. Because our factory equipment is lifelong warranty, we are very glad to serve you.

 The operational principles of impact crusher

 The materials are entered into an impact crusher by the feed hopper, and then they will be divided into two parts by the feeder. One part is entered into a high-speed rotating impeller from the middle of the feeder. The acceleration speed in the impeller can reach hundreds of times the acceleration of gravity, and then it is ejected from the three uniform flow passages at 60-70 meters per second. Firstly, a part of the material that falls from the feeder will be hit and broken, and then it impact on the material lining layer of the vortex branch together, bouncing off the material liner, impacting to the top slant of the vortex cavity, and changing its direction of motion, deflecting downward movement, and forming a continuous material curtain from impeller channel. Such a material is subjected to two or even multiple probability impact, attrition, grinding and crushing in the whirling cavity. The broken material is discharged from the lower discharge gate. The closed loop system is formed with the circular screening system and it. Generally, the material can be broken into 20 parts in three times cycles. During the whole process of crushing, the materials impact and break with each other. They won’t directly contact with the metal element. However, they will impact, rub and break with the material liner, which will reduce the pollution and prolong the wear time of the machine. The vortex flow the whirling chamber eliminates the dust pollution. The ingenious internal airflow’s self circulation inside the vortex flow eliminates the dust dispersion.

Ball Mill

The Handling Materials and Main Types of Ball Mill:

Ball mill is a key equipment for grinding materials, widely used in powder-making production line such as cement, silicate sand, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc.

 Ball mill can grind various ores and materials with the dry type or wet type. There are two kinds of ball mills, grate type and overfall type due to different ways of discharging material.

 The Interior Structure of Ball Mill:

The machine is composed by feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance. The machine is in stable and reliable working condition.

 Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice.

 The Working Principle of Ball Mill:

This machine is a skeleton pattern ball mill with horizontal cylindrical turning gear, drive by outer gear and two hoppers. The material goes to the first hopper after the spiraling by the quill shaft from the feeding equipment. The hopper has ladder sheathing or corrugated sheathing with steel balls inside, which will fall under the effect of centrifugal force by the barrel and grind material. After the kibbling in the first hopper, by monolayer partition panel, the material will enter the second hopper, which has plane scale board with steel ball inside to grind material. The powder material will be discharged from the grid plate to finish the grinding.

Ball mills are widely used in production industries, such as cement, silicate products, new building materials, refractory materials, chemical fertilizers, black and ferrous metals and glass ceramics and others. It can grand things in dry-type and wet-type for all kinds of ore and other grindable materials.

 The Structure Characteristics of the Ball Mill

 The ball mill consists of feeding parts, discharging parts, rotary parts, transmission parts (reducer, small transmission gear, motor, electronic control) and other main parts. The hollow shaft adopts cast steel, and the inner lining of it can be dismantled. The rotary large gear is machined by casting hobbing process, with a wear-resistant lining plate in the barrel, which has the ability of wear resistance. Our machine runs smoothly and has reliable performance. According to the material and discharge way, we can choose dry-type ball mill or wet-type ball mill.

 Quick-wear Parts of the Ball Mill

 The quick-wear parts of the ball mill mainly refer to the lining boards, the wear and usage time of the liner are related to the cost and production effect of the ball mill. Then how to identify the advantages and disadvantages of the lining boards. We can conclude it mainly from three steps, the first to see is the lining plate casting and smelting process, the next step is to check whether the lining plate quenching and tempering treatment are qualified, and at last, we need to look at the lining board material carefully. At present, the common lining materials in the market are high chromium cast iron, low alloy wear-resistant cast steel and high manganese steel material. These three kind of materials of lining boards of the three kinds of have good wear resistance ability. GUIKUANG machinery welcome you to our factory to inspect the production process of ball mills and the lining plate’s manufacturing techniques.

 The Operation Principle of the Ball Mill

 The material is entered into the hollow shaft by the feeding device, and then it enters the first warehouse of the ball mill evenly. There are stepped lining plates or corrugated lining plates with different sizes of steel balls inside the warehouse. The cylinder rotates to produce centrifugal force for bringing the steel ball to a certain height and then it falls down. This produces heavy blow and grinding effects to the material. After the rough grinding process, the material enters the second warehouse through a single clapboard. The warehouse is lined with a scale-board with steel balls for further grinding. The powder is discharged by the discharging grate plate to finish the grinding operation.

 The Classifications of the Ball Mill

 According to the different materials processed by the ball mill, GUIKUANG machinery produces the following kinds of ball mill, such as gold ball mill, black manganese ore ball mill, nickel ore ball mill, tin ore ball mill, copper ore ball mill, pomegranate ball mill, andalusite ball mill, aluminum grey ball mill, molybdenum ore ball mill, fluorite ball mill and so on.

The vertical grinding machine is a kind of advanced grinding equipment designed and developed on the basis of the extensive use of advanced technology at home and abroad, combined with many years of various mill machine production experience. It is an ideal equipment for grinding industry, which integrates crushing, drying, grinding and grading transportation. It can be widely used in cement, electric power, metallurgy, chemical industry, nonmetallic mineral industry and so on. It is used to grind lump, granular and powdery raw materials into the required powder materials.

The main structure of the vertical grinding machine

Vertical grinding machine mainly consists of powder separator, grinding roller device, grinding disc device, the pressure device, reducer, motor, shell and so on. The separator is a highly efficient and energy saving powder separator. Grinding roller is used to crush and crush materials. The millstone is fixed on the output shaft of the reducer and is the place where the grinding roller compacts the material. The pressurizing device is a component for grinding roller to provide enough pressure to crush material.

Working principle of the vertical grinding machine

When the vertical grinding machine is working normally, the motor drives the grinding disc to rotate through the reducer, and the material falls from the feed inlet to the center of the grinding disc through the lock air feeder. With the rotation of the grinding disc, the material moves to the edge of the grinding disc under the action of the centrifugal force. Through the ring groove on the grinding disc, the material is crushed by the roller rolling. The crushed material is brought up at the edge of the grinding disc by high-speed airflow from the wind ring and the large particles fall directly onto the grinding disc to re-ground. When materials in the air flow pass the upper separator, under the action of rotating rotor, the coarse powder falls from the cone bucket to the grinding disc and is re-ground. The qualified fine powder goes out with the airflow and is collected by the dust collecting device, that is, the product. Materials containing moisture are dried in contact with hot air flow. By adjusting the hot air temperature, it can meet the requirements of different humidity materials and achieve the required product moisture. By adjusting the separator, the required thickness of different products can be achieved.

Main features of the vertical grinding machine

1.Low investment cost

Due to the integration of crushing, drying, grinding and grading, the system is simple and the layout is compact. The area is about 50% of the ball milling system, and it can be arranged in the open air. Therefore, the investment cost can be reduced greatly.

2.Low operating cost

(1)High grinding efficiency : using the grinding roller to directly crush the material on the grinding disk, low energy consumption, and 30% ~ 40% less energy consumption than ball grinding system.

(2)Less abrasion: longer service life and less wear due to the fact that the grinding roller does not contact the grinding disc directly during work and that the grinding roller and the lining plate are made of high quality materials.

3. Strong drying ability

Because the hot air directly contacts with the material in the grinding, it has strong drying ability and saves energy. By adjusting the hot air temperature, it can meet the requirements of different humidity materials.

4. Easy operation

(1)The system is equipped with automatic control system, which can realize remote control and easy operation.

(2) Vertical grinding machine is equipped with equipment to prevent direct contact between roller sleeve and disc liner to avoid destructive impact and severe vibration.

5. Stable product quality

Because the material stays in the grinding for a short time, it is easy to detect and control the product granularity and chemical composition, reduce the repeated grinding, and stabilize the product quality.

6. Convenient maintenance

Overhauling the oil cylinder, turning the rotating arm, replacing the roll sleeve and liner plate is convenient and quick, reducing losses in downtime.

7. environmental protection

Vibration is small, noise is low, and the whole equipment is sealed, the system works under negative pressure, no dust spillover, clean environment, and meets the national environmental protection requirements.

The process flow of the vertical grinding machine

According to the location of humidifying tower and dust collector, the vertical grinding machine has two different layout schemes, namely, the three fan system and the double fan system. A cyclone collector is used for the collection of products. This arrangement reduces the working negative pressure of the system and the amount of gas passing through the dust collector. The electric dust collector can also be replaced by the bag dust collector as the final dust collector. The dust collector can be the electric dust collector or the bag collector, and the grinding gas is directly entered into the dust collector. The system reduces the number of equipment and simplifies the system configuration.

It also has the characteristics of continuous powder making dry-type, the concentration of grain size, continuous fine fineness, compact structure and so on. The particle size of the pendulum grinding mill can be adjusted in the range of 0.125-0.044mm (equivalent to 120-325 mesh) according to different requirements.

The Application Ranges of the Pendulum Grinding Mill

 The Pendulum Grinding Mill is widely used. Common grinding materials and usage ways are as follows:

Soil types: clay, China clay, bentonite, magnesia, clay, bauxite, etc.

Non-metallic ores: gypsum, talc, graphite, fluorite, calcite, limestone, calcite, barytes, apatite, tabular spar, feldspar, quartz and so on.

Metal oxides: manganese iron ore, chromite, Ilmenite, bauxite and so on.

Chemical compounds: coke, lime coke, smelting coke, barium sulfate and so on.

Others: the products of the pendulum grinding mill can be used in many industries. For example, the metallurgical industry produces the magnesia as the refractory layer of blast furnace; the oil industry uses the barytes powder to seal the injector; some industries produce bentonite powder as the lubricant for drilling; the chemical industry produces different stone powder as the filler in rubber, plastics, paper making and paint; porcelain, glass, enamel, white cement, gypsum and magnesia products are all processed by pendulum grinding mill.

The pendulum grinding mill is mainly used for grinding non-inflammable and explosive mineral materials, Moh’s hardness of which is below 7 level and humidity of which is below 6%.

The micro powder mill is a highly efficient flour milling equipment, which was made on the basis of high-pressure powder mill and was improved by fineness classification technology. The advanced fineness classification technology of Germany and Japan adopts the principle of fluid mechanics. Scientists studied diligently with a quiet mind, and then they designed a new micro powder mill. So they solve the problem of high cost successfully. It is a high-efficiency and high-pressure micro powder mill.

The Application Scopes of Micro Powder Mill

The micro powder mill is mainly suitable for grinding of conventional materials and the ultra-fine powder processing of non inflammable and non explosive materials, such as kaolin, limestone, calcite, talcum, marble, barite, gypsum, iron oxide red, iron oxide green, aluminum hydroxide, pigment, bentonite, clay, coal, activated carbon and so on, the humidity of which is less than 8%, and the Moh's hardness of which is less than level 6.

The Structure Characteristics of Micro Powder Mill

The high-pressure micro powder mill mainly consists of the main engine, blower, superfine analyzer, finished cyclone powder collector, bag filter and connecting duct. According to user needs, it can provide with auxiliary equipment such as the hoist, storage bin, electric cabinet, feeder, crusher and so on. In the grinding mill room, the grinding roller assembly is hung on the grinding cradle through the cross arm shaft. The grinding cradle, spindle and the relieving tool post are fixed. The pressure spring is tightly pressed on the outer end of the cantilever housing of the grinding roller bearing chamber by a tension rod. Taking the transverse load axis as the supporting point, the grinding roller is firmly pressed on the inner surface of the grinding ring by the spring pressure.

When the motor is rotated through the drive, the blade of the blade is synchronized with the grinding roller, and the roller rolls around the surface of the grinding ring and rotates around itself. The analysis machine drives the rotating of the impeller through the motor drive. The speed adjustment of the analysis machine determines the fineness of the powder. The relieving tool in the relieving tool post and the grinding roller rotate at the same time. Then the grinding roller rotates on the inner surface of the grinding ring and revolves around itself. The analysis machine drives the impeller of the analysis machine through the motor drive device, and the speed adjustment of the analyzer determines the fineness of the powder.

The Main Features of Micro Powder Mill

The application scope of the high-pressure powder mill is much larger than that of the airflow mill.

Compared with other mills, the grinding pressure of grinding roller on the material can provide 800---1200Kg under the action of high-pressure spring. It saves energy. Under the same circumstance of output and fineness, the energy consumption of the system is only 1/3 of that of the airflow mill.

The investment is small and the efficiency is high. Under the same circumstance of output and fineness, the price is only 1/8 of the airflow mill.

Compared with the air mill, the production link is less. Firstly the airflow mill must crush the material of 20mm to the superfine powder of 100 mesh, and the high-pressure micro powder mill can make the material reached the average particle size about 6.5 μm to 12.5 μm for one time, of which the size is below the 20mm.

The grinding device adopts overlapping type multiple stage seal and has good sealing performance.

The dust removal effect of the mill can totally reach the national dust emission standard.
