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.
