Failure analysis and solution of screw conveyor blockage in fertilizer equipment

Fertilizer equipment screw conveyor is used for conveying fertilizer manufacturing process. https://www.fertilizerproductionprocess.com/production-line/fertilizer-disc-granulation-production-line-process.html 

Due to the small space for conveying materials, the machine is very sensitive to materials.When the screw shaft rotates, the material is easy to be entangled, and the intermediate suspension bearing is easy to block the material. Therefore, blockage is a common failure of screw conveyors. Blockage will affect output and increase power consumption. In severe cases, it will burn out the motor, twist the screw shaft, and affect the normal organic fertilizer production process.

There are many reasons for the blockage, and the following measures can be taken to prevent the blockage:

1. Reasonably select the technical parameters of screw conveyor, such as the speed of slow screw conveyor should not be too large.2. Strictly implement the operation procedures of fertilizer production process, start without load and stop without load, and ensure continuous and uniform feeding.3. Increase the discharge port or lengthen the end of the chute to solve the problem of poor or too late discharge. At the same time, a small section of counter rotating blade can be installed at the end of the discharge chute to prevent material blocking at the end.4. The materials entering the conveyor should be cleaned to prevent the blockage caused by large impurities or fibrous impurities entering the conveyor. Cleaning up the debris on the fertilizer equipment on time will help maintain the machine.5. Reduce the transverse dimension of the middle suspension bearing as much as possible to reduce the possibility of blocking when the material passes through the middle bearing.6. Install silo level indicator and blockage sensor to realize automatic control and alarm.7. Open an anti-blocking valve on the discharge end cover. When blockage occurs, due to the accumulation of materials, the anti-blocking door is opened, and the power is cut off by the stroke switch.

What is the development trend of organic fertilizer production process

Organic fertilizer production process uses straw, livestock and poultry organic matter as raw materials, and harmless treatment of pollutants through equipment to produce organic fertilizer. This production project mainly uses chicken, duck, goose, pig excrement and crop straw as the main raw materials, uses the natural fermentation of microbial flora and organic matter, adds nitrogen release agent, organic matter activator and other pollution-free additives, and makes high-efficiency organic ecological fertilizer after scientific treatment. Fertilizer manufacturing process is suitable for the local breeding and crop straw and other waste rich areas. Using straw and livestock manure as raw materials to transform into organic fertilizer, on-site production and on-site digestion can not only solve the straw outlet and fecal pollution, but also produce benefits. It is an efficient and environmental protection ecological development mode. Similar areas can also learn from the mode of straw fertilizer in organic fertilizer production line to find a way out for the comprehensive utilization of straw and breeding manure.

How to produce fertilizer? In the process of fertilizer equipment sales, we found that many users' raw materials are relatively dry chicken manure or pig manure, and some users even mixed some other materials to reduce the production cost of organic fertilizer. Organic fertilizer without professional fermentation treatment of fertilizer production process is often unqualified and not suitable for crop production.

Indoor fermentation tank is recommended for organic fertilizer production

It is recommended that the indoor trough fermentation of manure is more environmentally friendly for organic fertilizer production. How to produce fertilizer? From manure to organic fertilizer, the price has increased a hundred times, the key is to add fermentation bacteria to do fermentation treatment. Here is a brief introduction to the method of making organic fertilizer from manure and straw.

The organic fertilizer produ​ction process includes:

https://www.fertilizerproductionprocess.com/production-line/

Put the fresh manure cleaned from the farm on the same day into the fermentation workshop, add bacteria, synergists and other auxiliary materials, after heating, mixing and stirring, it becomes compost. In the high temperature, the germs and insects in the feces will be killed, and the macromolecular proteins are decomposed into small molecular proteins that are beneficial to the absorption of crops. The biological fermentation process can effectively prevent the generation of harmful and odorous gases such as hydrogen sulfide, amine gas and indole in the feces, and completely remove the odor in the feces.The compost is sold in bags after the second aging and decomposing, or directly made into granular fertilizer and stored. Fermentation cycle of manure organic fertilizer production process is generally 7-10 days, so we recommend customers to use indoor fermentation tank for fermentation. For example, open-air fermentation will be affected by the environmental temperature, and more importantly, it meets environmental protection requirements and will not affect the surrounding odor during the fertilizer production process.

If feces are not effectively processed and utilized, it is a serious source of environmental pollution. If they are utilized through fertilizer manufacturing process, it is also a valuable resource. The main feces are chicken and duck manure, pig manure, cattle and sheep manure, quail manure, pigeon manure, etc. If it is vesicular manure, it needs to add accessories such as straw, mushroom residue, sawdust, bagasse, coal ash and other dry materials, neutralize the water value before fermentation, otherwise it is already.

Main process of disc granulation bio organic fertilizer manufacturing process

Taking the disc granulator as the core granulation equipment, the organic waste is processed into organic fertilizer. The following is the whole fertilizer manufacturing process. 1. Send the treated sludge (organic waste, industrial sludge, etc.) and proper amount of qualified raw materials such as nitrogen, phosphorus and potassium into the raw material mixer according to the proportion and mix them evenly. 2. It is transported to the feeder, and the evenly mixed material is added to the rotating disc of the disc granulator through the continuous rotation of the disc. 3. Sprinkle the treated microbial strains on the materials in the disc through the liquid component distributor of the disc granulator, so that each particle is coated with microbial strains from the inside to the outside. The rotating disc and its edge produce friction and centrifugal effect on the material, which makes the material move in a circumferential direction, and the powder particles rub and squeeze each other, and gradually agglomerate into a ball. Due to the difference of particle mass, the gravity and centrifugal effect are different. When the gravity and centrifugal force increase enough to overcome the friction between particles, they will be thrown out of the disk, and the smaller particles will still stay in the disk and continue to gather fine particles. 4. The organic fertilizer particles are transported to the biological bacterial fertilizer drum dryer, and the large air volume produced by the fan and the low temperature treated by the induced draft device are used to complete the preliminary drying of the fertilizer. Due to strains, the drying temperature is strictly controlled below the temperature at which strains survive. 5. Qualified particles are transported to the organic fertilizer cooler, and the fertilizer is cooled by natural or strong cooling air 6. The material is transported to the finished product rotary screener​ machine, and the fine particles are directly returned to the feeder, as the core to participate in the adhesion of the particles into balls. The large particles are crushed by the pulverizer and returned to the disc homogenizer to continue to participate in ball formation. https://www.fertilizerproductionprocess.com/fertilizer-screener-series/drum-screener-machine.html 7. The microbial bacteria will be lost on the surface of the particles of the biological fertilizer that comes out of the dryer, and the microbial species on the surface of the particles will be supplemented by spraying on the coating machine. 8. The processed bio-organic fertilizer is transported to the fertilizer granule packing machine for weighing, packaging and storage. 9. Drying, cooling and workshop dust are exhausted after being treated by cyclone dust collector, labyrinth dust removal room and wet scrubbing.

What equipment is needed to produce organic fertilizer

Organic fertilizer is a popular fertilizer product in the agricultural market. What equipment is needed for the organic fertilizer production process?

Poultry manure organic fertilizer manufacturing process

1. The recovered chicken manure, sheep manure and cattle manure are directly sent to the fermentation area.2. Poultry manure is piled after primary fermentation and secondary aging to eliminate the odor of livestock manure. Fermentation bacteria can be added at this stage to decompose the crude fiber so that the particle size after pulverization meets the particle size requirements of granulation production.3. Crush the fermented materials that have completed the secondary aging and stacking process and enter the mixing and stirring system. Before mixing and stirring, according to the formula, add N, P, K and some other trace elements into the mixing and stirring system and start mixing.4. Transport the mixed materials into granulation equipment, and use fertilizer disc granulator to make granules.5. After the wet particles are dried by the drum dryer to remove moisture, they enter the cooling system6. After the material is lowered to room temperature, the screening starts, and the product particles that meet the requirements enter the coating machine, and the packaging starts after the coating film is wrapped. The granules that do not meet the requirements are crushed by the pulverizer and returned to the granulation system, and then continue to be granulated after being processed by the pulverizer.7. Automatic weighing and packaging of finished products.

Therefore, the entire fertilizer production process is mainly to compost and ferment poultry manure, and then use the decomposed compost for granulation. First of all, the raw materials of organic fertilizer can be chicken manure, cow manure, pig manure, etc. The equipment for producing organic fertilizer is basically the same. Now the common equipment in the fertilizer industry are: compost fermentation equipment, batching equipment, mixing equipment, crushing equipment, granulating equipment, drying and cooling equipment, screening equipment, coating equipment, packaging equipment.

Disc fertilizer manufacturing process for processing fungus residue and manure peat

The disc granulator can process many raw materials, such as cow manure, chicken manure, sheep manure, pig manure, duck manure, peat soil, silica fume, sludge, drug residue, mushroom residue, etc. How to produce fertilizer? Disc fertilizer production process can meet most fertilizer processing requirements.

Disc fertilizer manufacturing process

The disc granulator is composed of an angled tray and a supporting structure. There are many types of disc granulator, with diameters of 0.8m, 1m, 1.5m, 1.8m, 2m, 2.8m, 3m, etc.The inclination angle and the rotating speed of the disc are adjustable. The material mixed by the mixer is sent to the top of the disc by the belt conveyor, and continuously enters into the disc quantitatively. The material in the disc is bonded by a spray of adhesive and wrapped into granules. As the disc rolls, the particles grow up gradually.Due to the remarkable grading capacity of the disc granulation machine, large particles float on top and are continuously discharged from the bottom of the disc. The smaller particles remain in the plate and stick with the newly added material and continue to grow.

Advantages of fertilizer disc granulator

The disc granulator granulates very uniformly, returns very little material, and has a large production capacity. An ordinary disc pelletizer can produce 1-3 tons of finished fertilizer per hour. In the fertilizer production process, the disc granulating machine is currently the most used granulation equipment. It has the advantages of simple structure, low cost and convenient maintenance.

How to use disc granulation machine

1. Check whether the reducer is filled with gear oil and whether the direction of rotation of the disc is correct before starting and starting.2. After running and pressing the start button, the host starts, and observe whether the equipment is operating normally, whether there is vibration, and whether the rotation is stable.3. After the filler and equipment are running normally, you can add materials and water.4. After granulation adjustment and filling, the angle of the disc can be adjusted according to requirements to make the granules reach the required size.

10,000 t/y of cow manure organic fertilizer production process and equipment

Treatment of cow manure

1. Decomposition method:

Collect cow dung and cow urine, mix with hay and rotten silage to make compost, and let it ferment. In the fermentation process, the compost turner machine is used to fully ferment the cow dung. This can only be achieved by turning the dump in time and evenly. Now some places are very dry and some places are very wet, which will affect the quality of fermentation.

2. Drying method:

Drying method is divided into mechanical drying method and natural drying method. Mechanical drying is a drying method using dryer, which can achieve the purpose of deodorization and sterilization. It is also a widely used drying method. The natural drying method is to mix the fresh cow dung alone or mixed with a certain proportion of bran, spread it on the cement floor or plastic cloth, turn it at any time, let it dry naturally, dry in the sun, then crush it, and mix it into other feeds for feeding. This method is low cost and easy to operate, but it is greatly affected by the weather and easy to cause environmental pollution.

3. Fermentation method:

The fermentation method is to add certain microbial agents or enzyme preparations and other auxiliary materials to cow dung, and then ferment at a suitable temperature, and the resulting products are used to feed chickens, pigs, fish and other animals. For example, if cow manure is fermented with silage, as long as there is enough water and soluble carbohydrates, cow manure can be silaged together with other poultry manure, crop straw, forage grass or other roughage. When silage, the ratio of manure and forage or other feed is preferably 1:1. This can convert part of non-protein nitrogen into protein and kill almost all harmful microorganisms.

The selected rotary screener mach​ine requires low vibration, low noise, convenient screen change, and is equipped with a screen surface cleaning device. It is recommended to equip a return system: the unqualified granular materials that are screened out are conveyed by a belt elevator, re-pulverized and sent to the granulator to continue granulation, which helps to improve the continuous operation capacity of the production line. https://www.fertilizerproductionprocess.com/fertilizer-screener-series/drum-screener-machine.html

5. DryingUse an organic fertilizer drum drying machine to further remove moisture from the sieved particles to meet the standard requirements of organic fertilizer moisture content.6. CoolingCooling the granular materials with a cooler helps the storage and quality of the granules.7. PackagingThe granular materials cooled by the organic fertilizer equipment are conveyed into the finished product warehouse through the bucket elevator. Granular materials can be quantitatively weighed and packaged through automatic packing scale.

Production equipment and cost input of cow manure organic fertilizer

In addition to the initial equipment cost and civil engineering investment, the raw material cost, transportation cost, labor cost and packaging cost should be considered in the production process of cow manure organic fertilizer. If organic fertilizer plants cooperate with farms, the situation will be very different. In the original site where manure is stacked, greenhouses and fermentation tanks will be invested by the farms, and the organic fertilizer manufacturers will invest in purchasing equipment to deal with manure, which can also reduce investment or production costs. The organic fertilizer production realized the cooperation with the farm, and the capital investment was greatly reduced.
