The Necessity of Spraying Devices in Organic Fertilizer Disc Granulators

Spraying devices are an indispensable component of organic fertilizer disc granulator machines,  directly determining granulation effect, production efficiency, and finished product quality, playing a crucial role in organic fertilizer production.

Organic fertilizer raw materials are mostly dry powders and finely crushed organic matter, lacking sufficient viscosity to spontaneously aggregate into spheres. The spraying system, through uniform atomized water spraying, provides a binding medium for the material, allowing powder particles to adhere to each other and grow layer by layer, which is fundamental to normal granulation. Without spraying, the material merely slides and scatters within the disc, making it difficult to form regular granules, hindering granulation operations.

Proper spraying controls particle shape and size. By adjusting the water volume, spray position, and atomization effect, the material can be guided to roll orderly, producing round, uniformly sized granules, reducing powder and irregularly shaped materials, and lowering the load on subsequent screening. Stable water supply also prevents loose and easily broken granules, improving the strength of the finished product.

For bio-organic fertilizers, the spraying method also affects product quality. Using atomized spraying instead of direct water injection prevents excessive localized moisture from causing clumps and sticking to the discs, while also avoiding water jets that could break up the material and damage functional bacteria. Precise water control maintains the material's moisture content within the optimal range for granulation, balancing molding quality with subsequent drying costs.

Furthermore, the spraying system alleviates material sticking to the discs. Moderate humidification reduces dry powder emissions, improving the workshop working environment; combined with a suitable spray angle, it minimizes large-area material adhesion to the disc bottom and edges, reducing the frequency of manual cleaning and ensuring continuous equipment operation.

What are the application scenarios of double screws compost turning machines?

Double screws compost turning machine, with their large turning depth, strong processing capacity, and good anti-tangling effect, are mainly used in medium to large-scale fermentation projects and are the main equipment for trough-type aerobic fermentation.

They are most commonly used in large-scale bio-organic fertilizer production lines, adaptable to fermentation tanks 6–11 meters wide and 1.5–3 meters deep, and can process mixtures of livestock and poultry manure, straw, mushroom residue, and humus. The dual-shaft counter-rotation breaks up long fibers and mixes materials evenly, significantly improving fermentation uniformity, shortening the composting cycle, and meeting the needs of continuous mass production in factories.

They are also widely used in large-scale livestock farms. Large quantities of manure and wastewater generated by pig farms with tens of thousands of heads, large-scale cattle farms, and chicken farms are turned, oxygenated, dehydrated, and deodorized by this machine, achieving on-site harmless treatment and resource utilization, solving environmental problems while producing high-quality organic fertilizer.

It also widely serves the environmental solid waste disposal field, capable of handling high-moisture, high-viscosity waste such as municipal sludge, kitchen waste, distiller's grains, traditional Chinese medicine residue, and sugar factory filter mud. The equipment is anti-tangling and does not easily stick to materials, efficiently completing material fermentation and volume reduction, meeting the requirements of solid waste resource utilization projects.

In addition, edible mushroom bases and garden waste treatment sites often choose this equipment to ferment mushroom residue, dead branches and straw, and other agricultural and forestry waste. With an automated control system, it can also be used in closed, solar-powered fermentation workshops, achieving unattended operation.

Precautions for Processing Ammonium Chloride with a Double Roller Press Granulator

 Ammonium chloride is a commonly used nitrogen raw material. It is brittle, highly hygroscopic, and slightly corrosive. When producing it using a double roller press granualtor, it is crucial to control four aspects: raw material management, equipment protection, operating parameters, and safe operation and maintenance, to ensure molding results and the lifespan of the fertilizer production machine.

Raw material pretreatment is the primary step. Strictly control the moisture content; the raw material moisture should be stable between 8% and 14%. Excessive moisture easily leads to moisture absorption, clumping, and adhesion to the roller skin, resulting in incomplete granules and poor feeding. Insufficient moisture increases the material's brittleness, resulting in more fragments after extrusion and insufficient strength in the finished product. The raw material must be sieved to remove impurities, and a magnetic separator should be used to remove iron filings, stones, and other hard objects to prevent hard impurities from getting stuck in the roller gaps, scratching the roller skin, and causing equipment overload. Potassium chloride, monoammonium phosphate, humic acid, and other materials can be mixed for granulation as needed; a proper ratio can improve molding performance.

Operating parameters should be adjusted as needed. Fine-tune the gap between the two rollers according to the target particle size, while controlling the feeding speed to ensure that the material fills the roller gap evenly and avoids idling or localized material accumulation. Ammonium chloride extrusion molding requires no binder; pure material can be formed. Maintain uniform equipment operation during production, reduce start-stop frequency, and prevent material from becoming damp and caking inside the machine.

Focus on equipment corrosion prevention and sealing. Ammonium chloride dust and moisture can corrode the roller skin, machine housing, bearings, and seals. Use corrosion-resistant oil seals at the shaft ends, and regularly lubricate the bearing seats with grease to prevent powder intrusion. After each shift, promptly clean the roller surface and machine cavity of any residual material to prevent moisture absorption, scaling, and corrosion of parts. Regularly inspect and reapply anti-corrosion coatings to the painted surfaces and metal contact surfaces of the machine body.

Dust Reduction Solution for Half-Wet Material Crusher(compost crusher)

Dust from half-wet material crusher(compost crusher) primarily originates from the feeding, crushing chamber, discharge, and equipment gaps. Considering the high moisture content of the materials, comprehensive management can be implemented through four aspects: sealing, negative pressure dust collection, material pretreatment, and operational control.

First, strengthen the overall machine sealing. Install flexible dustproof cloth covers and buffer hoppers at the feed inlet to reduce material drop and prevent dust from being carried upwards by airflow. Replace the sealing strips on the machine body inspection doors, flange interfaces, and shaft ends with corrosion-resistant rubber, and fill gaps with sealant. Add a dust baffle to the main shaft head to prevent dust leakage through the shaft gaps. Connect a sealed chute to the discharge port for fully enclosed conveying, eliminating bottom dust leakage.

Second, implement a negative pressure dust collection system, which is the core method. Install air collection hoods at the crushing chamber, feeding, and discharge points, connected to bag filters, to create a negative pressure environment. During operation, dust is promptly sucked away, preventing outward diffusion. To address the issue of filter bag clogging caused by high-moisture materials, anti-stick membrane filter bags are selected, paired with a pulse cleaning device to ensure stable dust removal efficiency.

Then, material pretreatment is crucial. Strict control of raw material moisture content is essential, maintaining it within the 30%–50% range. Excessively dry materials easily generate dust, while excessive moisture leads to equipment clogging. Large pieces of material are broken up beforehand to reduce dust generation during crushing, and dry, hard impurities are screened out, reducing dust generation at the source.

The Benefits of Adding Air Conditioning to Windrow Compost Turning machines

Adding air conditioning to the cab of a windrow compost turning machine is a practical configuration suitable for the harsh working conditions of fermentation workshops. It improves the working environment, protects personnel, and safeguards the electrical control components of the compost produciton machine, offering significant overall value.

Organic fertilizer fermentation sites are typically hot and humid year-round, accompanied by dust, ammonia, and other odors. During summer open-air operations, the temperature inside the cab can easily exceed safe levels, leading to heatstroke and fatigue for operators, impacting work efficiency and posing safety hazards such as operational errors. Air conditioning effectively regulates the indoor temperature, creating a comfortable operating environment, keeping personnel in good condition, and extending the duration of each work session. In cold winter weather, the air conditioning's heating function raises the cabin temperature, preventing operator stiffness and ensuring flexible and precise operation.

Simultaneously, the enclosed cab combined with the air conditioning system creates positive pressure, preventing dust and harmful gases from entering the vehicle, reducing the harm of harmful substances to the respiratory tract, and lowering the risk of occupational diseases.

In addition, the cab houses precision components such as instrument panels, control circuits, and electronic switches. High temperatures, humidity, and low temperatures can accelerate circuit aging, seal failure, and even cause short circuits. Air conditioning provides constant temperature and dehumidification, stabilizing the cabin environment, slowing down wear and tear on electrical components, significantly reducing the probability of equipment circuit failures, and minimizing downtime for maintenance.

Wear and Tear Specifications for New Type Organic Fertilizer Granulator Parts

New type  organic fertilizer granulator are divided into two types: agitator teeth and roller extrusion. Wear is concentrated on wear-resistant parts that directly contact the material. The rate of wear is determined by the impurities, moisture content, and coarse fiber content of the raw material.

The core wear parts for wet agitator tooth granulation are the granulating teeth, the inner liner of the cylinder, and the shaft end seal. The agitator teeth, constantly impacting coarse fiber manure, wear thins every 3-6 months under normal operating conditions; when the straw content is high, they need to be replaced every 2-3 months. The alloy liner, subjected to material scouring and friction, develops pits and material adhesion after about a year, requiring replacement in batches. The end-span oil seals are easily corroded by damp fertilizer powder, leading to ash ingress and oil leakage; on average, a set needs to be replaced every 2-4 months, but proper maintenance can extend this to six months. Regularly adding grease to the bearings can delay wear; insufficient grease can easily cause short-term damage.

The main wear parts for roller extrusion granulation are the roller skin and the forced feeding blades. Roller skins are the most frequently worn parts. Ordinary cast steel roller skins wear down smoothly in 6-10 months under normal production, while high-wear-resistant alloy steel roller skins can last 12-18 months. Stones or iron blocks mixed in with the raw material can instantly damage the mold grooves, significantly shortening their service life. The feeding auger blades, constantly pushing powder, wear thin and deform every 3-5 months, causing unstable feeding and affecting molding. Bearing seats are subjected to compression and vibration; if the seal breaks and fertilizer enters, the bearings will overheat and fail.

Commonly worn small parts: belts, springs, and spray nozzles. High dust levels and large load fluctuations accelerate the cracking of V-belts; they should be replaced regularly every 2-5 months. Spray nozzles are often clogged and corroded by fertilizer residue; they should be replaced as needed.

Power Configuration of Organic Fertilizer Disc Granulator

The power system of the organic fertilizer disc granulator consists of three parts: the main turntable drive, auxiliary spraying, and a small scraper motor. The core power is driven entirely by the main motor. The main unit typically uses a national standard three-phase asynchronous motor, with power matched to the disc diameter. A 2.5-meter disc usually uses an 11kW motor, and a 3-meter disc uses a 15kW motor. The motor is connected to a reducer via a V-belt. The reducer's output shaft pulls a large gear at the bottom of the disc, causing the disc to rotate at a uniform speed. The material is rolled into granules by the tilt angle of the disc.

The reducer is mostly a gear reduction structure, used to reduce speed and increase torque, offsetting the resistance from the rolling material and preventing the motor from overheating due to overload. Fixed scrapers are installed on the sides of the disc. In small models, the scrapers scrape material automatically by the disc's rotation. In medium and large models, a separate small motor and reducer drive are added to actively scrape off material adhering to the disc wall, preventing material accumulation and clumping that affects granulation. The system is equipped with a spray water supply device. Small-scale systems use electric water pumps for water supply, while high-power disc granulation production lines utilize variable frequency water pumps. A small motor controls the water intake, precisely adjusting the material's moisture content.

When should a double screws compost turning machine be prioritized?

Assuming a standard cement fermentation tank and a sealed fermentation workshop are in place, a double screws compost turning machine is the preferred choice. It is ideal for raw materials such as chicken manure, pig manure, and municipal sludge, when mixed with straw, mushroom residue, and sawdust. The double-helix forward and reverse rotation provides strong crushing and agglomeration capabilities, ensuring even material turning without dead corners, effectively preventing anaerobic odor and incomplete composting.

For plants with limited space that want to increase composting capacity, this machine is the preferred choice. The turning depth can reach 1.6–1.8 meters, allowing for deeper expansion of the fermentation tank. It holds more material than large wheel compost turning machines within the same footprint, resulting in higher land utilization. It is also suitable for shortening the fermentation cycle and producing high-quality bio-organic fertilizer and horticultural organic fertilizer. The material is finely broken up, with sufficient aeration, leading to faster composting. With appropriate deodorization equipment, it is easier to meet environmental protection requirements.

This equipment is prioritized for large-scale processing plants planning automated production and reduced labor costs. It features electrically controlled automatic reciprocating movement, and with the addition of a transfer cart, one machine can rotate multiple fermentation tanks. One person can oversee the entire fermentation process. It is also suitable for long-term continuous production and those seeking to control maintenance costs. The spiral blades are made of wear-resistant high-manganese steel, ensuring high durability with proper maintenance, and the overall operating energy consumption is low.

However, it is not recommended for open-air windrow composting where investment in civil engineering for trenching is undesirable, or where the proportion of excessively long straw is too high and easily entangles the spiral blades. Tracked or wheeled compost turners offer better cost-effectiveness in these cases.

The Function of Bearing Housings in a Double Roller Granulator

The bearing housings of a double roller press granualtors are the supporting bases of the main shaft of the pressure rollers. They bear the alternating loads throughout the extrusion process and primarily perform four core functions: positioning, load bearing, limiting, and installation. These functions directly determine the accuracy of the roller gap and the stability of the equipment.

First, load bearing. The instantaneous extrusion during granulation generates enormous extrusive force. The material's reaction force is entirely transmitted to the bearing housings through the main shaft. The entire weight of the bearings and main shaft, as well as the extrusion impact load, are borne by the bearing housings, preventing the shaft from being suspended and deformed, and ensuring the roller skin adheres closely to the extrusion molding process.

Second, precise positioning and limiting. A fixed bearing housing on one side locks the axial displacement of the main shaft, while a movable bearing housing on the other side slides laterally with a hydraulic cylinder to adjust the roller gap, ensuring that the two pressure rollers operate in parallel and do not shift. The installation datum of the bearing housings determines the coaxiality of the two rollers; positioning deviations will result in uneven roller surface contact and uneven particle thickness.

Third, protecting the bearings and storing lubrication space. The bearing housing encloses the bearing and, with the help of oil seals and labyrinth seals, isolates it from dust, moisture, and fine fertilizer powder, preventing these particles from entering the bearing and causing ball bearing wear and seizing. The housing has pre-installed oil channels and grease fittings to hold lubricating grease, continuously supplying oil to the bearing for cooling.

Fourth, the entire machine is fixed and vibration-damped. The bearing housing is secured to the machine frame base with anchor bolts, dispersing and transmitting the extrusion vibration to the frame, buffering the instantaneous impact of large hard objects entering the roller, and reducing overall machine vibration.

Discharge Precautions for Half-Wet Material Crusher (compost crusher) Discharge Bin

Half-wet materials generally have a moisture content of 50%–70%, and their high viscosity makes them prone to clogging, bridging, and blockage. Discharge control focuses on preventing clogging, ensuring stable material flow, and protecting downstream equipment.

Control the discharge opening and discharge speed. Sudden, large-scale opening of the gate is strictly prohibited. Concentrated discharge of wet material can easily overload and stall the downstream conveyor belt and elevator. Discharge at a uniform speed according to the feed load of the half-wet material crusher(compost crusher) to ensure continuous and uniform material intake, avoiding intermittent discharge that could lead to unstable subsequent batching. If the discharge volume fluctuates, fine-tune the gate opening to maintain a consistent material layer thickness.

Prevent bridging, clumping, and blockage within the bin. Before discharge, check the bin walls for any material adhering to them. Do not forcibly open the gate if adhesive material has accumulated and formed an arch. Use a vibration device to break up the arch first. Do not allow personnel to enter the bin for cleaning to prevent material collapse and injury. Remove large clumps of material in advance to avoid clogging the discharge port and chute. For prolonged shutdowns, promptly empty any remaining material from the silo to prevent it from drying and caking.

Monitor material moisture content. In rainy weather, when raw materials are damp and sticky, reduce the discharge rate to minimize material buildup on the silo walls. If the moisture content is low and the material is loose, slightly increase the discharge rate. If the discharged material contains large, uncrushed clumps of impurities, stop the discharge and return it to the crusher for further crushing to prevent large pieces from damaging downstream equipment.

Inspect the discharge port and sealing areas, paying attention to leaks and dust spills from the chute, and repair any damage promptly. Prevent foreign objects from falling into bearings and the discharge point. Immediately shut down the discharge gate if any downstream batching or conveying equipment malfunctions to prevent backflow and blockage of the discharge silo. Regularly stop production to clean the silo, removing any adhering layers from the walls to reduce blockages and ensure stable continuous operation of the entire bio-organic fertilizer produciton line.

Windrow compost turning machine turning depth

The turning depth of a windrow compost turning machine refers to the maximum vertical working height of the material pile that the drum teeth can reach. It is a core parameter in windrow fermentation, directly determining the overall oxygen supply and uniformity of composting within the fermentation layer.

The mainstream turning depth for conventional models on the market is 1.2–1.8 meters, smaller models are mostly 1.2–1.4 meters, standard models are 1.4–1.6 meters, and deeper models can reach 1.6–1.8 meters. This value is determined by the drum diameter, frame lifting stroke, and tooth length. The factory parameters are fixed, but minor adjustments can be made via the hydraulic system.

In actual operation, it is recommended that the effective turning depth be 10–15 centimeters lower than the rated maximum depth. If the material pile height is equal to or exceeds the rated depth, the bottom material cannot be turned, easily forming an anaerobic layer, resulting in foul odors and incomplete composting. Too low a height reduces operating efficiency and lowers site utilization. For conventional fermentation windrows, a stack height of 1.0–1.5 meters is recommended, suitable for most general-purpose machines.

Material characteristics will affect the actual operating results. High-moisture, high-viscosity manure and sludge are prone to compaction and caking; therefore, a shallow to medium depth (1.2–1.4 meters) should be used to ensure the teeth penetrate the material layer. For loose materials such as straw and mushroom residue, a depth of 1.5 meters or more can be used to improve site utilization.

The Impact of Organic Fertilizer Ball Shaping Machines on Particle Moisture Content

 The operation of organic fertilizer ball shaping machines slightly reduces the moisture content of the particles. The overall impact is mild, and significant dehydration does not occur. Specific changes are influenced by operating conditions, machine model, and operating methods.

During fertilizer produciton machine operation, the particles tumble at high speed, rub against each other, and collide. Rapid airflow on the surface removes free moisture from the particle surface. Under normal operating conditions, the moisture content generally decreases by 1%–2%. If the initial moisture content of the particles is high and the surface is moist, the moisture loss will be slightly greater, with a maximum decrease of about 3%. For particles that are already relatively dry, the moisture change is negligible.

If the matching spray device is activated to add water or binder, it will slightly increase the surface moisture. This is mainly used to improve particle roundness and reduce dust. The spray volume needs to be controlled to prevent the particles from becoming damp and soft again.

Rounding machines have no heating structure; they rely solely on physical friction and natural airflow for dehydration. The internal temperature increase is limited and does not deeply remove bound water from the particles. Therefore, it does not change the internal humidity of the particles and will not cause particle cracking.

Adjustment of the Scraper Device in an Organic Fertilizer Disc Granulator Machine

The scraper is a key component in an organic fertilizer disc granulator machine preventing sticking to the disc, regulating the material layer, and ensuring granulation quality. Adjustment must follow the principle of static calibration during shutdown and dynamic fine-tuning during operation, with safety as the top priority.

Before debugging, be sure to shut down the machine, disconnect the power, and lock the equipment. First, adjust the gap between the scraper and the bottom of the disc. The standard is controlled at 3-5 mm. Too large a gap will cause material to clump on the disc, resulting in uneven particle size; too small a gap will accelerate wear between the scraper and the disc surface, producing abnormal noise. The gap should be uniformly calibrated around the circumference using the support bolts. Next, adjust the scraper tilt angle. The standard setting is 15°-25°, tilting in the direction of disc rotation. Too large an angle will disrupt the material's tumbling state, affecting pelleting; too small an angle will result in incomplete cleaning and material sticking to the disc. Simultaneously, control the insertion depth; the front end of the scraper should extend into the material area to about one-third of the disc diameter.

Perform a no-load test run to confirm that the scraper is free from jamming and friction, and that a thin layer of material remains on the disc surface, indicating a normal state. During production with material, make minor adjustments as needed: for large areas of material adhesion, reduce the gap and increase the tilt angle; for a large number of large particles, appropriately raise the scraper and slow down the angle to break up material clumps; for material accumulation on the edge of the disc, adjust the gap of the auxiliary side scraper to 2-3 mm.

Fermentation Process of Double Screws Compost Turning Machine

 The double screws compost turning machine is the main equipment for windrow fermentation of organic fertilizer. It utilizes a double helix auger structure to complete the entire process of turning, aeration, mixing, and dehumidification. The process is simple and flexible, and it is widely used in small and medium-sized organic fertilizer plants, planting bases, and livestock and poultry farm manure treatment.

Before fermentation, the raw material ratio is determined by mixing organic materials such as livestock and poultry manure, straw, and mushroom residue, adjusting the moisture content to 55%–65%, adding fermentation bacteria as needed, and then thoroughly mixing and piling the mixture into long strip-shaped piles. The height and width of the piles are adapted to the operating range of the equipment.

Fermentation is divided into three stages. In the heating stage, the material naturally begins fermentation. When the temperature rises above 45℃, the double helix compost turner is activated. This compost production machine relies on the rotation of two sets of helical shafts to push and disperse the material, breaking the sealed layer of the pile, supplementing oxygen, and expelling ammonia and water vapor, promoting rapid microbial reproduction. During the high-temperature stage, the material temperature is maintained at 55–65℃, with regular turning and tossing. This kills insect eggs and harmful bacteria, achieving harmless treatment, and prevents localized anaerobic fermentation and acidification. During the cooling and maturation stage, the frequency of turning and tossing is gradually reduced, allowing the material to cool slowly and undergo nutrient conversion until complete maturation.

Precautions for Replacing Bearing Housings in a Double Roller Press Granulator

Replacing bearing housings in a double roller press granulator requires strict adherence to safety regulations and assembly standards to prevent issues such as abnormal noise, overheating, oil leaks, and premature bearing wear, ensuring stable equipment operation.

Before operation, the power supply to the equipment must be disconnected and warning signs posted to prevent accidental start-up. The work area must be cleaned beforehand to ensure it is dust-free and free of debris. Verify the model and specifications of the new bearing housing and ensure it is matched with original factory parts. Before disassembly, mark the alignment positions of the bearing housing and frame to ensure reassembly accuracy. Loosen bolts diagonally in stages; brute force on one side is strictly prohibited to prevent housing deformation. For heavy bearing housings, hydraulic pullers or low-temperature heating should be used for disassembly. Directly striking the housing and journal with a hammer is prohibited to avoid damage to components.

Before installation, thoroughly clean the journal and bearing housing holes with a cleaning agent to remove oil, burrs, and impurities. For interference fit components, use uniform heating at 80-100℃ for assembly; open flame heating is prohibited. Install according to the original markings, strictly calibrating coaxiality. Tighten the fixing bolts diagonally and evenly in stages to prevent uneven load distribution.

During assembly, inspect oil seals, O-rings, and other seals. Replace any damaged parts. Ensure the sealing lip faces inwards towards the bearing to prevent dust ingress and grease leakage. Fill the bearing cavity with dedicated lithium-based grease, controlling the grease level to one-third to one-half full to avoid overheating from excessive grease or dry friction from insufficient grease.

What are the differences between vertical and horizontal half-wet material crushers (compost crushers)?

Both models are suitable for crushing high-moisture manure, straw, and biogas residue. The core differences lie in their structural capacity, crushing effect, site adaptability, and operation and maintenance.

In terms of structural layout, the vertical half-wet material crusher(compost crusher)has a compact, vertical body with the feed inlet located at the top. The material is crushed by its own weight, and internally, multiple layers of hammers crush it layer by layer. The horizontal model has a horizontally placed body with side feeding. The rotor rotates horizontally at high speed, shearing and impacting the material, and has a larger chamber volume.

The capacity specifications differ significantly. The vertical model is generally smaller, with an hourly output of 1-5 tons, suitable for small workshops and small-scale composting pretreatment. The horizontal model has a stronger processing capacity, reaching 5-15 tons per hour, matching large and medium-sized bio-organic fertilizer produciotn lines, meeting the needs of continuous processing of large quantities of materials.

The crushing characteristics differ. The vertical model's layered crushing is fine, with uniform and stable output particle size and good refining effect, making it suitable for pre-granulation materials. Horizontal crushers have stronger impact force and are better at breaking up large lumps and long-fiber materials. They offer high crushing efficiency but produce slightly coarser output particles, making them ideal for early-stage fermentation and composting.

Depending on the location and application scenario, vertical crushers require less space, offer flexible installation, and can be placed even in narrow workshops. They also have lower energy consumption per unit. Horizontal crushers have a larger footprint, are heavier than fertilizer produciton machine, but offer stronger operational stability and are suitable for open workshops and mass production environments.
