Chicken manure organic fertilizer crusher is a key equipment used in organic fertilizer production lines to crush chicken manure raw materials into smaller particles or powders. Its working principle varies depending on the design of different models, but can be roughly divided into two categories: hammer crusher and roller crusher. Here is a detailed explanation of the working principles of these two common types:
Hammer crusher
working principle
The hammer crusher mainly relies on the high-speed rotating hammer head to impact the chicken manure raw materials and achieve the crushing effect. Specifically:
High speed rotating rotor: The crusher is equipped with one or more high-speed rotating shafts (rotors) with hammer heads inside. The rotor rotates at high speed under the drive of the motor, generating strong power.
The impact effect of the hammer: When the chicken manure raw material enters the crushing chamber, the high-speed rotating hammer directly hits the chicken manure, and the huge impact force instantly destroys the structure of the chicken manure, causing it to split into smaller fragments.
Sieve screening: A sieve is often installed inside or at the outlet of the crushing chamber. Only when chicken manure fragments pass through the sieve holes can they leave the crushing chamber, ensuring that the particle size of the crushed material meets the set requirements. Large pieces of material that fail to pass through the sieve are returned to the crushing chamber for further processing until the desired particle size is reached.
Roll crusher
working principle
The roller press crusher uses two parallel and relatively rotating rollers to compress and shear chicken manure raw materials, thereby achieving the purpose of crushing. Its characteristics are as follows:
Double roller squeezing: The organic fertilizer crusher is equipped with a pair of pressure rollers that rotate in opposite directions, and the distance between them can be adjusted. Chicken manure raw materials enter between two pressure rollers through the feeding inlet.
Compression and Shear Forces: With the rotation of the pressure roller, chicken manure is gradually brought into the increasingly narrow space between the two pressure rollers, subjected to strong compression and shear forces. This process will cause changes in the physical structure of chicken manure, which will eventually be crushed into smaller particles.
Discharge: The crushed chicken manure particles are discharged through the gap between the pressure rollers, usually without the need for additional screening equipment, as the distance between the pressure rollers already determines the maximum particle size of the final material.
general comparison
Two types of organic fertilizer crushers each have their own advantages and disadvantages. Hammer crusher is suitable for processing dry chicken manure with low moisture content, with fast crushing effect, but may generate a lot of dust; Roller press crushers perform better on chicken manure with higher moisture content, producing less dust, but with slightly lower crushing efficiency, and relatively higher equipment and maintenance costs.
The selection of which type of chicken manure organic fertilizer crusher should be comprehensively considered based on the specific characteristics of chicken manure raw materials, expected crushing particle size, production volume, and budget. The correct selection and reasonable setting of crusher parameters are of great significance for improving the quality of organic fertilizers and the overall efficiency of production lines.
