Chain crusher is a commonly used crushing equipment in the production line of chicken manure organic fertilizer. It is mainly used to crush dried chicken manure cakes, fermented lumps or other organic materials into small particles or powders suitable for granulation, in order to improve the efficiency of organic fertilizer production and the quality of the products. Below is a detailed explanation of the working principle of the chain crusher:

working principle

The core component of a chain crusher is a rotor composed of high-speed rotating chains, which are fixed to a spindle driven by an electric motor and rotate at high speed. When the material enters the crusher chamber, it is subjected to the impact and shear force of the high-speed moving chain, and the large blocks in the material will be quickly crushed. At the same time, collisions between materials and between materials and the inner wall of the machine body will further refine the materials until the desired particle size distribution is achieved.

Key components

Chain: Made of wear-resistant materials with various shapes, commonly including flat chains, toothed chains, etc. Their design purpose is to increase the contact area with the material and improve crushing efficiency.

Rotor: composed of multiple parallel arranged chains, driven by the main shaft to achieve high-speed rotation.

Body: usually cylindrical in shape, with lining plates inside to protect the machine body from wear and tear, and also an important interface for material crushing.

Sieve: located at the bottom or side of the machine body, the size of the sieve hole can be adjusted according to the required particle size. Only materials with a particle size smaller than the sieve hole size after crushing can be discharged through the sieve, while larger particles are sent back to the crushing chamber for further crushing.

Running process

The material is first fed into the feed inlet of the chain crusher. Due to the high-speed rotation of the rotor, the material is immediately strongly impacted by the chain, and large pieces of material are quickly crushed. Subsequently, the material moves downwards under the action of gravity and mechanical force, constantly colliding with the chains on the rotor, the lining plate of the machine body, and other materials, further refining. Finally, small materials are discharged through the sieve, while larger particles remain in the crushing chamber until they reach the appropriate size.

Chain crushers have been widely used in the chicken manure organic fertilizer processing industry due to their simple structure, high crushing efficiency, and strong adaptability. However, in order to ensure long-term stable operation and high work efficiency, regular maintenance and upkeep are very necessary, such as regularly checking the degree of chain wear, cleaning residual materials, etc., which are all important aspects of daily management that cannot be ignored.

The sheep manure organic fertilizer production line is a professional production line that converts sheep manure into high-quality organic fertilizer. Its process usually includes multiple steps such as raw material pretreatment, fermentation, drying, screening, batching, granulation, cooling, and packaging. Below is a detailed introduction to the main process and granulation flow of the sheep manure organic fertilizer production line:

1、 Raw material pretreatment

Collection and preliminary crushing: Collect fresh or dried sheep manure and crush it preliminarily for better mixing with other auxiliary materials.

Raw material mixing: Mix crushed sheep manure with a certain proportion of auxiliary materials (such as straw, rice husk, sawdust, etc.) and microbial agents to adjust the carbon nitrogen ratio and moisture content of the materials, which is beneficial for the subsequent fermentation process.

2、 Composting fermentation

Composting construction: Stacking the mixed materials into strips or blocks for high-temperature aerobic fermentation, during which microbial activity accelerates the decomposition of organic matter.

Flipping ventilation: Regularly use organic fertilizer turning machines for flipping, increase oxygen supply, maintain suitable temperature and humidity conditions, and promote fermentation process.

3、 Drying and screening

Material drying: After fermentation, the material needs to be dried to reduce moisture content, usually using a dryer or natural air drying method.

Screening and grading: The dried material is screened through a vibrating screen to separate large chunks or impurities that have not been completely decomposed, resulting in a uniform and consistent matrix.

4、 Ingredients and granulation

Formula adjustment: Add appropriate amounts of chemical fertilizers and other trace elements as needed to adjust the nutrient composition of the finished organic fertilizer.

Granulation molding: Use an organic fertilizer granulator to press the prepared powdered material into granules. Common granulation methods include extrusion granulation, disc granulation, and drum granulation. Among them, sheep manure organic fertilizer production lines often use disc granulators or drum granulators to produce granular fertilizers.

5、 Cooling and encapsulation

Cooling treatment: After granulation, fertilizer particles need to be cooled to prevent deformation or breakage due to excessive heat.

Coating treatment: Some production lines will add a coating process, which coats a thin film on the surface of fertilizer particles to enhance their water resistance and stability, while also delaying nutrient release rate.

6、 Finished product testing and packaging

Finished product testing: Conduct physical and chemical index testing on the final product, such as pH value, organic matter content, total nutrients, etc., to ensure that the product quality meets the standards.

Finished product packaging: Use a packaging machine to bag, label, and prepare qualified products for sale.

The above is the basic process flow of the sheep manure organic fertilizer production line. It is worth noting that the specific operation of each step may vary depending on different production processes and equipment, so appropriate adjustments should be made according to the specific situation in actual operation.

The application of mobile dump trucks in the fermentation process of organic waste mainly involves the following key steps, which together constitute a complete fermentation process:

Raw material preparation: Firstly, the organic waste that needs to be fermented, such as livestock manure, crop straw, food processing waste, etc., is subjected to preliminary treatment, including crushing and mixing, to ensure the uniformity and suitable particle size of the raw materials, which is conducive to the growth of microorganisms and the fermentation process.

Composting pile construction: The process of stacking processed raw materials into long, rectangular piles of a certain height and width, commonly referred to as “fermentation piles”. The size and shape of the fermentation pile will be determined based on the type and quantity of raw materials, as well as the specifications of the mobile tipping truck.

Fermentation initiation: After the compost pile is built, microorganisms begin to decompose organic matter under suitable temperature, humidity, and oxygen conditions, and this process is called fermentation initiation. The activity of microorganisms generates heat, causing the temperature of the pile to gradually increase and enter the high-temperature fermentation stage.

Pile flipping operation: When the temperature of the pile reaches a certain height (usually between 50-70 ° C) and is maintained for a period of time, a mobile pile flipping truck is used for the flipping operation. The dump truck flips the pile to mix the internal and external materials, increase oxygen supply, promote microbial activity, and evenly distribute the temperature and humidity of the pile to prevent local overheating or excessive humidity.

Repeated flipping: During the fermentation process, it is necessary to regularly flip the pile according to the temperature and fermentation status of the pile. The frequency and timing of flipping depend on the temperature of the pile, the properties of the raw materials, and the progress of fermentation.

Maturity stage: When the temperature of the heap gradually decreases and no longer significantly increases, fermentation enters the maturation stage. At this point, most of the organic matter has been decomposed by microorganisms, the temperature of the compost pile tends to stabilize, and compost products begin to form.

Post processing and storage: After fermentation, compost products need to undergo further processing such as screening, crushing, drying, etc. to remove impurities, adjust particle size and moisture, and finally be packaged and stored for transportation and use.

The key role of mobile dump trucks in the fermentation process is to increase the oxygen supply to the pile, promote microbial activity, accelerate the decomposition of organic matter, and ensure uniform temperature and humidity of the pile, thereby improving fermentation efficiency and the quality of compost products. This process can not only effectively handle and utilize organic waste, but also promote the recycling of resources, providing sustainable solutions for agriculture and environmental protection industries.

Disc granulator and drum granulator are two commonly used organic fertilizer granulation equipment, which have significant differences in structure, working principle, scope of application, and performance. Here are their main differences in performance:

Structure and working principle:

Disc granulator: The granulation process of the disc granulator mainly occurs inside the inclined disc, and the material rolls into balls under the centrifugal force of the disc rotation. The tilt angle and rotational speed of the disc can be adjusted to control the size and shape of the particles.

Drum granulator: The drum granulator forms particles by rotating and rolling materials inside a rotating cylinder. There are usually specific structures inside the drum, such as screw propellers, to promote the formation and uniform distribution of particles.

Particle shape and strength:

Disc granulator: tends to produce more regular and round particles with uniform shape and size, and moderate strength.

Drum granulator: The particles produced may be more irregular, but by optimizing the internal structure and operating parameters of the drum, particles with higher strength and better wear resistance can be produced.

Applicable materials:

Disc granulator: more suitable for processing materials with low moisture content and moderate viscosity, such as dry organic waste.

Drum granulator: capable of processing a wider range of materials, including high humidity and high viscosity materials such as certain types of sludge, high humidity organic waste, etc.

Production capacity and energy consumption:

Disc granulator: usually suitable for medium and small-scale production, with relatively low energy consumption.

Drum granulator: suitable for large-scale production, with large production capacity, but relatively high energy consumption.

Equipment maintenance and operation:

Disc granulator: The structure is relatively simple, and maintenance and operation are relatively convenient.

Drum granulator: The structure is complex, and maintenance and operation are relatively complicated, requiring regular inspection and maintenance of the internal structure of the drum.

Cost and return on investment:

Disc granulator: With relatively low initial investment costs, it is suitable for producers with limited budgets.

Drum granulator: The investment cost is relatively high, but in the long run, due to its high efficiency and large production capacity, it may have a better return on investment.

The choice between disc granulator and drum granulator should be determined based on comprehensive factors such as production demand, material characteristics, budget, production scale, and long-term planning. In practical applications, it may be necessary to combine these two devices to achieve the best granulation effect and production efficiency.

In the process of processing organic fertilizers from cow manure, the disc granulator usually follows a standardized production process aimed at converting organic waste such as cow manure into high-quality organic fertilizer particles. The following is the basic process of using a disc granulator to process organic fertilizer from cow manure:

Raw material preparation:

Collecting cow manure: Firstly, collect fresh or dry cow manure as the main raw material for organic fertilizers.

Pre treatment: Preliminary crushing and mixing of cow manure, adjusting its moisture content to a suitable range (usually 30% -40%) to promote the granulation process.

Raw material mixing:

Adding auxiliary materials: In order to improve the physical properties and nutritional composition of fertilizers, an appropriate amount of auxiliary materials can be added, such as straw powder, sawdust, peat, limestone powder, etc.

Mixing evenly: Mix cow manure and auxiliary materials thoroughly to ensure the uniformity of each part of the raw materials, laying a good foundation for the subsequent granulation process.

Granulation process:

Disc granulation: The mixed raw materials are fed into a disc granulator, and through the rotation of the disc and the action of its internal structure, the raw materials are formed into uniform particles at suitable humidity.

Adjusting particle size: By adjusting the parameters of the disc granulator, such as the inclination angle of the disc, rotation speed, and moisture content of the raw material, the particle size and shape can be controlled to meet the needs of different fertilizer products.

Drying and cooling:

Particle drying: After granulation is completed, the particles need to be dried to reduce their moisture content, improve their stability and strength, usually using a dryer.

Cooling: The dried particles need to be cooled to room temperature to prevent quality changes during storage and packaging due to excessive temperature.

Screening and packaging:

Screening: Use a screening machine to screen the cooled particles, remove unqualified particles, and ensure the consistency and quality of the product.

Packaging: Packaging the screened qualified particles for storage, transportation, and sale.

quality testing:

Finished product inspection: Conduct quality inspection on packaged organic fertilizer particles, including particle hardness, moisture content, nutritional analysis, etc., to ensure that the product meets relevant standards.

Using a disc granulator to process organic fertilizers from cow manure not only effectively treats and utilizes organic waste such as cow manure, but also improves the production efficiency and product quality of fertilizers, promotes resource recycling, reduces environmental pollution, and meets the requirements of green agriculture and sustainable development.

In order to ensure fermentation efficiency, product quality, and operational safety during the fermentation process using a mobile dump truck, the following key points need to be noted:

Raw material pretreatment: Before fermentation, raw materials (such as livestock manure, crop straw, etc.) need to undergo appropriate pretreatment, including crushing and mixing, to ensure the uniformity and appropriate particle size of the raw materials. The moisture content of the raw materials should also be controlled within an appropriate range (usually 50% -60%), as excessive or insufficient moisture can affect the fermentation effect.

Fermentation heap construction: The size and shape of the heap should be designed according to the specifications of the mobile tipping truck and the characteristics of the raw materials to ensure the efficiency of the tipping operation. The stack should not be too high or too wide to avoid insufficient oxygen or high temperature in the central part.

Controlling fermentation temperature: During the fermentation process, controlling the temperature of the heap is crucial. Excessive temperature (over 70 ° C) may kill beneficial microorganisms and reduce fermentation efficiency; If the temperature is too low, fermentation will be slow. When using a mobile forklift, the flipping operation should be carried out in a timely manner according to the temperature changes of the stack to adjust the temperature.

Timely flipping: The flipping operation should be carried out in a timely manner according to the temperature of the pile, the characteristics of the raw materials, and the fermentation process. Flipping too early or too late can affect the fermentation effect. Usually, when the temperature at the center of the pile reaches 55-65 ° C and is maintained for a period of time, flipping should be carried out.

Monitoring fermentation parameters: During the fermentation process, key parameters such as temperature, humidity, and oxygen content of the heap should be regularly monitored to ensure the controllability of the fermentation process and product quality.

Avoiding secondary pollution: During the flipping and fermentation process, measures should be taken to prevent secondary pollution, such as controlling dust, reducing odors, and avoiding the spread of harmful microorganisms.

Safe operation: When operating a mobile dump truck, safety operating procedures should be followed to ensure the safety of operators, such as wearing appropriate protective equipment to avoid equipment running on unstable or unsuitable ground.

Fermentation cycle and maturity assessment: The length of the fermentation cycle should be determined based on the characteristics of the raw materials and the fermentation effect. After fermentation is completed, the maturity of the compost product should be determined by testing its temperature, organic matter content, pH value, and other indicators to ensure the quality of the organic fertilizer.

Post processing and storage: After fermentation, organic fertilizer products need to undergo further processing, such as screening, crushing, drying, etc., to adjust their particle size and moisture content, and then be appropriately packaged and stored to maintain their fertilizer efficiency and stability.

By paying attention to these matters, it is possible to ensure that the mobile dump truck performs at its best during the fermentation process, improving fermentation efficiency and the quality of organic fertilizer products, while ensuring operational safety and environmental protection.
