Processing capacity: 1-8 tons/hour
Motor power: 22-75kW
Discharge particle size: 40-50 mesh
Moisture content range: 20%-60%
Applicable materials: Composted organic matter, chicken manure, cow manure, pig manure, biogas residue, mushroom residue, straw, rice husks, humus, etc.
Casing: Mostly horizontal or vertical, welded with wear-resistant steel plates, the interior walls are typically treated with an anti-stick treatment to reduce material sticking. A feed inlet is located at the top, a discharge outlet is located at the bottom, and some models are equipped with a cleanout door for convenient disposal of residual material.
Crushing system: The core system consists of a "rotor + crushing blade assembly." The blade assembly design varies depending on the material characteristics:
For highly sticky materials, spiral blades or agitating blades are often used, crushing the material through rotation, pushing, and squeezing to prevent accumulation.
For fibrous semi-wet materials, claw blades or hammer blades are used, combining shearing and impact to sever fibers and break up clumps.
Drive system: Consisting of a motor, reducer, and coupling, this system provides the rotor with low-speed, high-torque power, preventing material sticking or splashing caused by high-speed rotation while ensuring a stable crushing process.
Anti-blocking Device: The feed inlet is equipped with a screw feeder to evenly control the feed rate. Some models feature a backflush device or vibration mechanism at the bottom of the casing to prevent material from clogging the discharge port through airflow or mechanical vibration.
Screening Device: A simple screen can be installed at the discharge port to separate uncrushed coarse material. Some models also support coarse material recirculation for secondary crushing.
Application Areas

3. Agricultural Waste Processing: Grinding silage, crop residue, and other waste for conversion into feed or fertilizer;

5. Food Processing Byproduct Processing: Processing fruit peels and pomace for resource utilization.
Working Principle of the Semi-Wet Material Pulverizer:
1. It utilizes a two-stage rotor for two-stage pulverization. The material is crushed into fine particles by the upper rotor, then conveyed to the lower rotor for further pulverization into a fine powder, achieving the optimal results of both material and hammer crushing. The material is then discharged directly at the discharge port.
2. It has no screen bottom, allowing it to crush over a hundred types of materials without clogging. Even materials freshly pulled from the water can be crushed without clogging caused by wet material pulverization, which could damage the motor and affect production.
3. It utilizes a high-alloy, wear-resistant hammer head and forged hammer blades, which are exceptionally strong and wear-resistant, exceeding the strength of ordinary hammer heads and extending the hammer blade's service life.
4. It utilizes bidirectional gap adjustment technology. If the hammer blade becomes worn, it can simply be moved and used again without repair. The particle size can be controlled by adjusting the gap between the hammer head and the liner.
5. Its high-tech operation allows for easy, one-person operation, ensuring safety, reliability, and ease of maintenance.
6. The centralized lubrication system is filled with oil. Under normal operation, the lubricating oil can be injected without stopping the machine.
Advantages of the Semi-Wet Material Pulverizer:
1. Targeted Processing of High-Wet Materials:
This pulverizer solves the problems of "sticking to the wall, clogging, and low efficiency" often encountered with conventional pulverizers. It is particularly suitable for crushing materials before and after fermentation in organic fertilizer production (e.g., pre-treatment of fresh manure and breaking up lumps in mature compost).
2. Reduced Material Loss:
The anti-sticking design reduces material residue on the chamber walls, improving material utilization; the low-speed crushing reduces material splashing and dust, making it more environmentally friendly.
3. Wide Adaptability:
It can process a variety of semi-wet organic wastes, such as municipal sludge, traditional Chinese medicine residue, and vinegar dregs, facilitating the resource conversion of "waste into organic fertilizer."

What materials are suitable for the semi-wet material grinder for organic fertilizer?
The semi-wet material grinder is designed for organic materials with a moisture content of 30%-60%. Its core processing targets include livestock and poultry manure (such as chicken, cow, and pig manure), biogas residue, sewage sludge, food waste, medicinal residue, mushroom residue, and mixtures of straw and manure. Due to the high moisture content of these materials, traditional grinders are prone to sticking and clogging. However, the semi-wet material grinder's special structural design allows it to efficiently process these "semi-wet, semi-dry" materials. For example, biogas residue fresh from a biogas digester can be directly fed into the grinder for grinding without the need for additional drying.
What is the key difference between a semi-wet material grinder and a conventional grinder?
The key difference lies in its ability to handle high-moisture materials. When handling materials with a moisture content exceeding 40%, conventional pulverizers are prone to material adhesion, leading to clogging of the pulverizing chamber and poor discharge. Semi-wet material pulverizers, on the other hand, can crush materials through shearing, squeezing, and tearing, while utilizing the centrifugal force generated by the high-speed rotation of the rotor to reduce material adhesion, ensuring stable operation in high-humidity environments.
How does a semi-wet material pulverizer work?
After entering the pulverizing chamber through the feed inlet, the material is initially crushed by the shearing and squeezing action between the high-speed rotating rotor (with blades or claws) and the stationary liner. Subsequently, the centrifugal force of the rotor throws the material toward the inner wall of the pulverizing chamber, where it collides with the liner and teeth, grinding it further into smaller particles. Material that meets the required particle size is discharged through a screen (or the gap in models without a screen), while material that does not meet the required particle size is circulated within the pulverizer until it meets the required particle size. Some twin-shaft models use two counter-rotating rotors that interlock with each other to enhance the tearing effect on sticky materials and reduce the risk of clogging.
What safety precautions should be taken when operating a semi-wet material pulverizer?
① Before feeding, remove metal, stones and other hard objects from the material to avoid damage to the rotor and blades;
② It is strictly forbidden to open the crushing chamber door when the equipment is running to prevent material splashing and injuring people;
③ Before shutting down, stop feeding first and wait until the material in the chamber is emptied before shutting down to avoid excessive load when starting next time;
④ Regularly check safety protection devices (such as emergency stop buttons and protective covers) to ensure sensitivity and effectiveness;
⑤ After handling corrosive materials (such as sludge), clean the equipment in time to prevent parts from rusting.
