Organic fertilizer equipment fertilizer crusher: Efficient crushing process and operation guide

by organic fertilizer production line

The fertilizer crusher is a key piece of equipment in an organic fertilizer production line. Its main job is to grind fermented organic materials (like livestock manure, crop stalks, and mushroom residue) into an even, fine powder. This ensures stability in later steps like granulation or packaging. How well it breaks down the material directly affects the quality of the final fertilizer and the production efficiency.

How It Works

1.Feeding and Initial Crushing

Material is fed into the hopper, either by conveyor belt or manually. High-speed rotating blades or hammers cut and break down large chunks into smaller pieces.

2.Fine Grinding

Inside the crushing chamber, the material gets hit repeatedly by hammers, teeth, or screens. It also gets rubbed and sheared. This breaks it down gradually into tiny particles (usually 1-5mm).

3.Screening and Discharge

Particles small enough to pass through the screen at the bottom are discharged. Material that’s still too coarse stays in the chamber for more grinding, ensuring a uniform final product size.

Operating Guidelines

1.Before Starting

Make sure the power voltage is stable and all bolts are tight. Check the crushing chamber is clear of hard objects (like stones or metal) to avoid damaging the blades.

2.During Operation

Feed evenly: Avoid overloading the machine, which can cause blockages or motor overload.

Moisture control: Keep raw material moisture content ≤30%. Wet material tends to stick to the screen.

3.Maintenance and Care

Lubricate bearings regularly.

Replace worn blades/hammers (generally check every 300 hours). Clean the screen after stopping to prevent corrosion and clogging.

In short, the fertilizer crusher is vital for improving fertilizer quality. Using it correctly extends the machine’s life and guarantees efficient grinding.

Structural Design and Analysis of a Rotary Drum Granulator

by organic fertilizer production line

As the core granulation equipment in an organic fertilizer production line, the structural design of a rotary drum granulator directly impacts granulation efficiency and product quality. Its overall design is centered around “efficient granulation, stable conveying, and adaptability to the characteristics of organic fertilizers.”

The rotary drum granulator‘s core working component is an inclined rotating drum, welded from steel plates. The inner wall is lined with a wear-resistant lining to prevent abrasion by humic acid and other components in the organic fertilizer raw materials, while also enhancing material friction to aid granulation. The drive system offers both constant and variable speed options.

The constant speed option is suitable for large-scale production with stable raw materials, while the variable speed option (8-15 rpm) can be adjusted to suit different raw materials: reducing the speed to prevent sticking when the liquid content is high, while increasing the speed to promote compact granules when the liquid content is low.The rotary drum granulator drum inclination angle is a critical parameter, typically 3-10 degrees. A too small angle causes the material to remain in the drum for too long, leading to agglomeration or oversized granules. A too large angle results in rapid material flow, insufficient granulation time, and loose granules. A 50-100mm high retaining ring is installed at the feed end to prevent loose powder from flowing back. The height of the retaining ring at the discharge end is adjustable. It can be raised to extend retention time when larger pellets are needed, and lowered or replaced with a spiral discharge ring for faster discharge. The blade angle matches the rotational speed, ensuring a uniform feed to the screen and preventing clogging.

The integrated cylindrical screen is key to finished product screening. Its aperture is customized to meet organic fertilizer requirements (2-5mm). Rotating synchronously with the drum, qualified pellets are discharged while unqualified, large particles are returned for reprocessing, achieving an integrated “granulation-screening” process. The flexible binder injection system allows for pre-injection, suitable for highly absorbent raw materials such as straw. Instantaneous injection allows for precise moisture control to prevent over-wetting. Both methods are equipped with metering pumps to ensure precise dosage (10%-15% of the total raw material) and guarantee pellet formation efficiency.

Key Steps and Practices for Establishing a Bio-Organic Fertilizer Production Line

by organic fertilizer production line

With the advancement of green agricultural development, market demand for bio-organic fertilizer continues to rise due to its advantages in improving soil quality and enhancing crop quality. Establishing an efficient and compliant bio-organic fertilizer production line requires a comprehensive approach, from planning to operational systems.

Preliminary preparation is the foundation. Production capacity should be determined based on the regional agricultural scale and raw material supply capacity. A daily output of 50-100 tons for small-scale lines and 100-300 tons for medium-sized lines is appropriate. Simultaneously, procedures such as obtaining a business license and environmental impact assessment approval should be obtained, with a focus on improving waste gas and wastewater treatment solutions for the fermentation process. On the raw material side, collaboration can be conducted with farms and agricultural product processing companies to ensure the supply of livestock and poultry manure, straw, and other materials. Simultaneously, a testing mechanism should be established to ensure that raw materials meet national standards.

Core equipment configuration determines production efficiency. Pretreatment requires a crusher and screener to break the raw materials into uniform particles. Fermentation equipment should be selected based on scale. For small and medium-sized plants, a trough-type turner should be used. Control the temperature at 55-65°C and the humidity at 50%-60% to accelerate composting. Subsequent equipment requires a mixer, granulator, dryer, cooler, and packaging machine. When selecting equipment, consider both production capacity and energy conservation and environmental protection, prioritizing low-energy, highly automated equipment to reduce labor costs.

Control of the production process directly impacts product quality. During pretreatment, microbial strains should be added proportionally to adjust the carbon-nitrogen ratio to 25:1-30:1. During the fermentation phase, temperature should be strictly monitored to ensure a 7-15 day composting cycle and prevent root burn. Finished products must be tested for moisture (≤30%) and organic matter (≥45%), and only qualified products can be shipped. Furthermore, a production log should be established to ensure quality traceability.

Production line operations must prioritize both market and technology. We can cooperate with agricultural cooperatives and large-scale growers to provide sample trials and technical guidance; at the same time, we pay attention to industry trends, introduce intelligent monitoring systems, adjust parameters in real time, and improve the stability of the bio-organic fertilizer production line and product competitiveness.
