What factors determine the output of an organic fertilizer granules machine?

fertilizer granulator Sep 9, 2025

When selecting an organic fertilizer granules machine, production capacity is one of the most critical considerations for users. The actual output is influenced by a combination of various factors.

1.Raw Material Characteristics

Composition and Formulation: The proportion of fibrous content, organic matter, moisture, oils, and sticky substances in the raw materials directly affects the difficulty and speed of pellet formation.

Moisture Content: Excess moisture can cause clogging, reducing output or even halting production. Too little moisture makes shaping difficult, increases the proportion of returned material, and lowers effective output.

Fineness and Uniformity: Finer and more uniformly mixed raw materials — after crushing and fermentation — flow better and are more easily extruded into pellets.

2.Equipment Model and Process

Machine Type: Flat die granulators are suitable for small to medium outputs and producing small to medium-diameter pellets. Double roller press granulators offer high output and low energy consumption, making them ideal for producing flat spherical organic fertilizer pellets. Disc granulators, on the other hand, allow adjustment of tilt angle and rotation speed to control output and pellet size.

Mold Specifications: For flat die and ring die granulators, smaller apertures and thicker molds increase extrusion resistance, reducing output per unit of time. Conversely, molds with larger apertures yield higher output.

3.Power System

A more powerful motor provides stronger driving force for the extrusion process, enabling it to handle more complex raw materials and higher production loads. This ensures stable and high output.

In summary, the production capacity of an organic fertilizer granules machine is a comprehensive metric influenced by multiple factors, including raw materials, equipment, and power. When aiming for high output, it’s important to consider the specific raw material conditions and select the appropriate machine type.

Analysis of the working principle of half-wet material crusher in organic fertilizer equipment

fertilizer granulator Sep 8, 2025

In organic fertilizer production lines, crushing is a crucial step. The half-wet material crusher is specifically designed to handle fermented materials with high moisture and fiber content. Its unique design concept combines three primary forces—shearing, tearing, and impact—to achieve efficient crushing.

1.Feeding and Preliminary Crushing
Pre-fermented organic materials (such as livestock manure, straw, sludge, etc.) are fed into the crushing chamber through the inlet. These materials typically have a moisture content of 25%–50%, making them sticky and prone to tangling.
2.High-Speed Rotor Rotation
At the core of the equipment is a heavy-duty rotor that rotates at high speed. Multiple sets of wear-resistant hammer blades or knives are mounted alternately on the rotor. Driven by an electric motor, the rotor generates strong torque and linear speed.
3.Shearing and Tearing
The rotating hammer blades and the wear-resistant tooth plate or liner fixed on the machine body form a narrow gap. As the material enters this gap, it is quickly cut and torn apart by the powerful shearing and tearing forces generated by the high-speed relative motion.

4.High-Speed Impact
Simultaneously, the initially crushed material particles are struck at high speed by the hammer blades inside the chamber, further breaking them down into finer particles.
5.Forced Discharge
The crushed fine particles are forced through the screen mesh at the bottom under the airflow generated by the rotor’s rotation and their own gravity, completing the crushing process. The screen mesh aperture can be replaced to meet the required fineness of the final product.

The half-wet material crusher is an indispensable key equipment in organic fertilizer production. Its unique working principle enables it to effectively process sticky, wet, and tangled organic materials without clogging.

Rotary drum granulator: Usage and working principle for organic fertilizer

fertilizer granulator Sep 8, 2025

The rotary drum granulator is a key piece of equipment in modern organic fertilizer production lines. It’s specifically designed to turn powdered organic raw materials (like livestock manure, straw, and humic acid) into uniform granules. Its high efficiency and low operating costs make it the top choice for large-scale organic fertilizer production.

Working Principle

1.Mixing and Moistening

Pre-treated organic materials enter the rotating drum through the feed inlet. Here, they are thoroughly mixed with a binder (like water or microbial solution) sprayed by the system, forming a moist material base.

2.Rolling and Granulation

Driven by a motor, the drum rotates at a tilt angle of 15-30° (typically at 20-40 r/min). Centrifugal force makes the material tumble and collide. Fine powder gradually clumps into small particles, which then grow larger through a “snowball effect”.

3.Polishing and Drying

In the rear section of the drum, the particles are smoothed and rounded. After being discharged, they can be further dried using a connected dryer to form hard, finished granules that resist crumbling (adjustable size: 2-8mm).

Key Operating Points

1.Raw Material Pre-treatment

Moisture Control: Powder moisture content needs adjusting to 30%-40%. Too high causes clumping; too low reduces granulation success.

Fiber Handling: Long-fiber materials must be pre-crushed to ≤5mm to avoid tangling in the equipment.

2.Optimizing Running Parameters

Speed Adjustment: Adjust the rotation speed based on the required granule size – larger particles need lower speeds.

Tilt Angle Setting: The standard angle is 25°. This can be fine-tuned via bracket bolts to change how long the material stays inside (residence time).

The rotary drum granulator achieves standardized organic fertilizer production through physical granulation. Combined with proper operation, it significantly improves the fertilizer’s commercial appeal and added value.

Structural Design and Analysis of a Rotary Drum Granulator

fertilizer granulator Sep 5, 2025

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

fertilizer granulator Sep 5, 2025

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.
