Written by fertilizer production line on August 27th, 2025. Leave a comment

The stable operation of organic fertilizer production equipment is key to ensuring fertilizer quality and production efficiency. A scientific maintenance system can effectively extend equipment life and reduce the risk of failure. Targeted maintenance measures are required for equipment throughout the entire process, from pretreatment to finished product packaging, tailored to its characteristics.

Maintenance of pretreatment equipment focuses on preventing blockage and wear. As the first step in processing raw materials such as straw and manure, the crusher requires daily inspection for blade wear and weekly sharpening to prevent blunting and reduced pulverization efficiency. Screening machines require regular cleaning of residual fiber debris and monthly inspection of screen tension to prevent vibration-induced loosening that reduces screening accuracy. For conveying equipment, special attention should be paid to the tightness of the conveyor belt and the lubrication of the rollers to prevent failures caused by frictional overheating.

Granulating equipment requires timely cleaning and maintenance. The disc granulator‘s disc should be cleaned of residual particles daily and coated weekly with an anti-stick coating to prevent material from clumping and sticking. Bearings should be lubricated with high-temperature resistant grease monthly to ensure smooth rotation. The roller surface of the roller granulator should be regularly inspected for wear and any dents should be repaired promptly to avoid compromising pellet quality.

Maintenance of post-processing equipment focuses on precision and safety. The hot air ducts of the drum fertilizer dryer should be cleaned of dust monthly to prevent blockages that affect thermal efficiency. The temperature sensor should be calibrated weekly to ensure precise control of the drying temperature. The fan filter of the cooler should be cleaned regularly to prevent debris from entering and affecting heat dissipation. The metering device of the packaging machine should be calibrated weekly, and the drive chain of the conveyor belt should be lubricated monthly to ensure accurate quantitative packaging.

Establishing an equipment maintenance mechanism provides long-term protection. Recording the time, content, and troubleshooting of each maintenance session can help identify recurring problems promptly. Operators should also receive professional training to ensure early resolution of minor faults and early prevention of major problems. Scientific maintenance not only reduces equipment failure rates but also ensures the continuity and stability of the organic fertilizer production line, providing reliable support for the green development of agriculture.

Cost Analysis of Chicken Manure Fertilizer Processing in an Organic Fertilizer Production Line

Written by fertilizer production line on August 21st, 2025. Leave a comment

Chicken manure is indeed a high-quality organic fertilizer raw material, rich in organic matter, nitrogen, phosphorus, potassium, various trace elements, enzymes, and microorganisms. Through standardized aerobic composting processes, it effectively degrades organic matter, kills parasite eggs and pathogens, and renders it harmless and stable. This can then be produced into commercial organic fertilizer through an organic fertilizer production line, creating economic benefits for chicken farms while fundamentally addressing environmental pollution.

However, processing chicken manure into commercial organic fertilizer does involve certain production costs, which can be primarily categorized into the following aspects. First, equipment investment is the core, one-time investment. A complete production line typically includes fermentation and compost turning equipment, a crusher, a mixer, a granulator, a dryer, a cooler, a screener, and an automatic packaging machine. The choice of granulator significantly impacts cost and product form. For example, a rotary drum granulator offers high output, a disc granulator offers a high granulation rate, and a flat die granulator is suitable for organic materials. Different granulator models have varying prices and energy consumption. Secondly, the costs of the pretreatment and fermentation processes cannot be ignored. Fresh chicken manure is sticky and moist, typically with a moisture content exceeding 70%, while the optimal fermentation moisture content needs to be adjusted to 50%-60%. Therefore, a large amount of auxiliary materials (such as straw, sawdust, and mushroom residue) are often required to adjust the moisture and carbon-nitrogen ratios. The procurement, transportation, and crushing of these auxiliary materials all incur ongoing costs.

The initial equipment investment for processing chicken manure in an organic fertilizer production line is relatively high, and ongoing operations also require ongoing investment. The cost level depends largely on the production scale, the degree of automation, the availability and price of raw materials, and the positioning of the final product. For large-scale chicken farms, although the initial investment is high, in the long run, the comprehensive benefits of addressing environmental pressures and creating economic value by turning waste into resources are significant, making the cost acceptable.

The role of uniform feeder in fertilizer production line

Written by fertilizer production line on August 20th, 2025. Leave a comment

In the continuous process of fertilizer production, the uniform feeder is the “nerve center” to ensure the coordinated operation of all links. Whether in compound fertilizer production line or organic fertilizer production line, it can improve the stability of raw material supply by more than 50%, and reduce product quality fluctuations from the source.

The uniform feeder adopts a design combining spiral conveying and frequency conversion speed regulation. The conveying screw is made of wear-resistant alloy material, which can adapt to raw materials with different physical properties such as urea granules, phosphate rock powder, fermented organic fertilizer, etc. The feeding amount can be set with an accuracy of ±2%. It can automatically adjust the conveying speed according to the needs of subsequent crushing, mixing, granulation and other processes to avoid raw material accumulation or feed interruption.

In the compound fertilizer production line, it can accurately convey basic raw materials such as nitrogen, phosphorus, and potassium according to the ratio, so that the nutrient deviation in the mixing link is controlled within 2%, which is much better than 8% of manual feeding. When handling wet organic fertilizer raw materials, its anti-blocking spiral structure combined with the vibration device can effectively avoid material adhesion and blockage, ensuring that the feeding amount per minute is stable at more than 98% of the preset value.

Compared with traditional feeding equipment, the uniform feeder does not require frequent manual adjustment, can reduce 80% of operational intervention, and reduce energy consumption by 30%. The material level sensor equipped with the equipment can monitor the inventory of the silo in real time, automatically start and stop the feeding, and realize unmanned continuous operation.

Whether it is connected to the crushing equipment or the mixer, the uniform feeder can lay a good foundation for the subsequent processes through the stable supply of raw materials. Choosing an appropriate uniform feeder can make the fertilizer production process smoother, the product quality more stable, and demonstrate the core value in large-scale production.

Application of Disc Granulators in NPK Fertilizer Production Lines

Written by fertilizer production line on August 20th, 2025. Leave a comment

In the NPK fertilizer production line, disc granulators are a widely used and highly favored granulation equipment.

The disc granulator‘s structure is relatively simple yet unique. It primarily consists of an inclined disc, a drive mechanism, and a spray system. The disc, the core of the granulation process, is typically constructed of high-strength steel to ensure it can withstand the various forces involved in the granulation process. The drive mechanism provides stable rotational power to the disc, ensuring it rotates at an appropriate speed.

The disc’s operating principle is based on the movement and interaction of the materials within the rotating disc. When the mixed NPK fertilizer raw materials are fed into the rotating disc, the disc’s tilt and rotational motion cause the materials to roll upward along the disc’s inner wall due to a combination of centrifugal force, friction, and gravity. During this rolling process, a spray system applies a binder to the material. The binder acts like “glue,” gradually binding the loose raw material particles together and causing them to aggregate and grow. Over time, these agglomerated particles continuously roll and collide within the disc, further compacting and shaping them, ultimately forming relatively uniformly sized round granules that roll off the disc’s edge, completing the granulation process.

Disc granulators offer numerous advantages. First, they produce fertilizer granules with high roundness, excellent appearance, and strong market competitiveness. Second, they are relatively simple to operate and easy to master, requiring minimal operator skill. Furthermore, disc granulators are highly adaptable and can produce fertilizer granules of varying sizes to meet diverse market demands by adjusting parameters such as disc speed, tilt angle, and binder spraying rate to meet specific production needs.

However, disc granulators also have limitations. For example, compared to some large-scale granulation equipment, their production efficiency may be relatively low, making them less suitable for large-scale industrial production. Furthermore, when processing high-viscosity raw materials, material may stick to the disc, affecting granulation efficiency and equipment operation. Nevertheless, due to their unique advantages, disc granulators still play an important role in the production of NPK compound fertilizers by small and medium-sized enterprises, as well as in production scenarios where the appearance of fertilizer granules is a high priority.

Where are flat die granulators used?

Written by fertilizer production line on August 19th, 2025. Leave a comment

With its unique extrusion molding principle, flat die granulators have demonstrated strong application potential in a variety of fields, making them an ideal choice for small- and medium-scale production. Their core structure consists of a flat die and a pressure wheel. The rotation of the pressure wheel squeezes the material through the die holes, forming cylindrical pellets. This simple and direct operation gives them wide applicability.

Flat die granulators perform exceptionally well in fertilizer production lines. When processing bio-organic fertilizers, they can directly pelletize wet fermented materials without the need for additional drying pretreatment, preserving the activity of beneficial bacteria while streamlining the production process. For nitrogen, phosphorus, and potassium compound fertilizers, their powerful extrusion capabilities can compress mixed powders into high-strength pellets, effectively eliminating the clumping problem associated with traditional pelleting. They are particularly suitable for producing high-concentration specialty fertilizers.

Flat die granulators are also essential for the feed processing industry. For poultry and livestock feed, they can compress raw materials such as straw powder and soybean meal into pellets, reducing feed losses during transportation. High-temperature extrusion kills parasite eggs in the raw materials, enhancing feed safety. In aquatic feed production, pellet density can be controlled by adjusting die hole size to meet the feeding needs of fish in different water layers.

In the environmental protection field, flat die granulators are a valuable aid in solid waste treatment. They can compress municipal sludge, agricultural and forestry waste, and other materials into fuel pellets, realizing waste resource utilization. These pellets have high combustion efficiency and low pollutant emissions, providing new ideas for the development of new energy sources.

The flat die granulator‘s advantages also lie in its flexible operation. By simply replacing dies with different apertures, a wide range of pellet specifications can be produced to meet the needs of diverse industries. The equipment also occupies a small footprint and is easy to install and maintain, making it suitable for small and medium-sized enterprises. As the concept of green production becomes increasingly popular, the flat die pelletizer, with its high efficiency, energy conservation, and versatility, continues to provide a reliable solution for material forming in various fields.

Precautions for Using a Compost Turning Machine

Written by fertilizer production line on August 19th, 2025. Leave a comment

As a core piece of equipment for material fermentation in an organic fertilizer production line, the proper use of a compost turning machine directly impacts production safety and fermentation efficiency. During daily operation, equipment inspection and parameter adjustment must be thoroughly monitored to ensure maximum performance.

A thorough pre-startup inspection is the first line of defense for safe operation. Check the tracks or running wheels for deviation and bolt connections for looseness. In particular, check for breakage or excessive wear on the turning blade assembly to prevent blades from falling off and causing damage to the equipment during operation. Also, clear the fermentation tank of hard objects such as rocks and metal to prevent them from becoming entangled in the turning mechanism and causing it to jam. Electrical system inspection is essential. Ensure cables are intact and grounding is reliable. Install a waterproof cover during rainy weather to prevent electrical leakage.

Parameter adjustment during operation is crucial for ensuring fermentation quality. Dynamically adjust the turning depth and frequency based on the material’s characteristics: High-protein materials like fresh livestock and poultry manure require more frequent turning to ensure ventilation and oxygen supply to prevent anaerobic decay. Crude fiber materials like straw can be turned more deeply to promote even mixing. The turning speed should be matched to the material’s moisture content. If the moisture content is too high, slow the turning speed to reduce clumping. Dry materials can be turned faster to improve efficiency.

Post-downtime maintenance determines the lifespan of the equipment.After each run, clean the blades and trough to prevent caking and compaction, which increases the load at the next start-up. Regularly lubricate bearings, chains, and other transmission components, and promptly replace severely worn parts. When the equipment is idle for extended periods, it should be stored in a dry location, the blades should be coated with anti-rust oil, and the electrical system should be disconnected from the power supply and dust-proofed.

Proper operation of a compost turning machine is not only essential for ensuring production safety, but also a scientific approach to improving fermentation efficiency and reducing operational costs, laying a solid foundation for the resource utilization of organic waste.

How to choose fertilizer manufacturing process plant

Written by fertilizer production line on November 27th, 2019.

Fertilizer promotes the development of ecological agriculture, and the demand is huge. Investment in building fertilizer plants has become a popular project. Some investors want to build small-scale fertilizer manufacturing process to save costs, while some investors in fertilizer plants are going to build large-scale fertilizer plants to save unit production costs.

So what should we pay attention to when purchasing fertilizer manufacturing process plant? Here are some notes.

Determine the type of fertilizer and producton site. Determining whether to produce organic fertilizer or compound fertilizer affects the choice of site. If organic fertilizer is produced, it should not be too far from the farm where raw materials are provided. The type of fertilizer determines whether compound fertilizer equipment or organic fertilizer equipment is needed. Different types of fertilizer equipment also have differences.

Determine the fertilizer granulator machine. Granulation is the key link in fertilizer production and plays an important role in the quality of manufactured fertilizer. Fertilizer granules are cylindrical, spherical and flat spherical in shape. The granules produced by granulators of different shapes are different. The choice of granulator is related to the scale of fertilizer plant construction and local market. Fertilizer factories have different investment scales, different production processes, and different supporting equipment.

If a small fertilizer plant is to be built, it is suggested to configure simple machinery and equipment to reduce investment in equipment. The small fertilizer production line is composed of crusher, mixer, granulator, drum screener and automatic packing machine. If organic fertilizer fermentation is needed, it can be carried out with batten fermentation and windrow turning machine. The advantages are that they are more in line with the principle of aerobic fermentation. It is not easy to form anaerobic fermentation. The fermentation is full and complete, and the fermentation speed is fast. Forklift trucks can also be used instead of turner (the effect is not as good as turner), which can be adopted in terms of saving investment. According to the local environmental protection requirements, choose dust removal settings, where environmental protection requirements are high, choose heavy dust settings to meet the local emission quality standards.

Investment in large and medium-sized fertilizer plants, fertilizer production equipment can choose turning machine, automatic batching system, loader feeding hopper, crusher, mixer, granulator, dryer, hot stove, cooler, feeder, screener, cyclone dust collector, packing machine, etc. Increase mechanical automation, save manpower and cost. Organic fertilizer tank fermentation, can choose simple compost turning machine, double screws compost turning machine (suitable for large yield).

Determine the manufacturer of fertilizer manufacturing process plant. Several fertilizer machine manufacturers were inspected, and the strength, scale and reputation of the manufacturer of fertilizer equipment were fully understood. It is better to inspect the production workshop, finishing workshop and assembly workshop of the enterprise, to know the product quality, processing equipment, production process of the enterprise, and whether the fertilizer equipment produced by the manufacturer is professional. Referring to the customer cases that the manufacturer has completed, on-site test machine, the production site can best show the real operation of the equipment. Looking for fertilizer equipment suppliers with perfect after-sales service, suppliers provide professional technicians to guide customers to install and debug equipment, so that the equipment can operate normally, and provide corresponding training services.

Determine the safety performance of fertilizer manufacturing process plant. Safety is the first, before purchasing, we need to consider whether the production line has safety devices, whether the machine design is reasonable, whether safety factors are taken into account, whether the parts are not welded properly, whether the bolts are tightened, whether there is pollution, and so on. In addition, whether the overall operation of the equipment is smooth and whether the design of the production line is reasonable are also matters needing attention, because it relates to the efficiency and quality of the operation of the equipment. With the permission of the manufacturer, the operator can try to operate it in practice and feel its state conveniently.

Fermentation Mode of Chicken Manure Organic Fertilizer Manufacturing Process

Written by fertilizer production line on November 27th, 2019.

Organic fertilizer, commonly known as farm manure, consists of various animal, plant residues or metabolites, such as human and animal manure, straw, animal residues, slaughterhouse waste, etc. Carbon-containing materials, mainly from plants and animals, are applied to the soil to provide plant nutrition as its main function. It not only provides comprehensive nutrition for crops, but also has long fertilizer efficiency. It can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity. It is the main nutrient in green food production.

The production of organic fertilizer must go through composting fermentation process. Composting is a process in which organic matter is continuously degraded and stabilized by microorganisms under certain conditions, and a product suitable for land use is produced.

Site selection

The site should be flat, near the water source and sunny from the leeward. It does not pollute the environment and is easy to provide water.

Chicken Manure Organic Fertilizer Fermentation Mode

1. Store the materials and add the bacteria proportionally. Water content should be controlled at 60%-70%. Fermentation of less water is slow and aeration of more water is poor. Oxygen deficiency will corrupt and produce odor.

2. The start-up temperature is better than 15℃ (can be operated in four seasons, not affected by season, fermentation in indoor or greenhouse in winter as far as possible), and the fermentation temperature should be controlled between 60 ~65℃.

3. Fermentation of organic fertilizer needs oxygen consumption fermentation. In the process of operation, oxygen supply measures should be increased so as to mix well, turn over frequently and ventilate properly. The windrow turner can work accurately to meet the requirements, it’s an important equipment of fertilizer fermention. Windrow compost turning machine has the advantage of high efficiency, smooth operation, strong and durable, even turning throw.

4. Fermentation

Warming-up stage: generally only one day is needed from room temperature to 50℃.

High temperature stage: generally only 2 days from 50-70℃.

Cooling stage: from high temperature to below 50℃, generally about two weeks. The temperature began to drop to normal temperature, indicating that the fermentation was completed.

FAQ of Organic Fertilizer Fermentation:

1. Slow warming: no or slow warming of the reactor

Material is too wet, too dry, there is not enough nitrogen source, and the pH is too low.

2. Heap temperature is too high: during fermentation, the heap temperature is more than 65℃.

Poor permeability.

3. Odor: The odor of rotten eggs or rotten eggs is emitted from the stack.

Ammonia content is too high, material stacking is too dense.
