1. The feed crusher has a gate or baffle in the lower part of the hopper, and the feed amount can be controlled by adjusting the opening of the gate or baffle. For example, when processing soybean cake, the bean cake should be broken first, and the maximum size after crushing should not exceed 40 mm; when processing hawthorn, rattan should be chopped first, and the length should not exceed 150 mm. By controlling the feed amount, work efficiency and crushing quality can be improved and overloading can be avoided. 2. Generally, the crusher has two or three kinds of meshes with different pore sizes. When using different meshes with different pore sizes, different particle sizes can be obtained. When installing the screen, the overlap method at the screen joint should be properly selected according to the rotation direction of the rotor, so that the direction of the inner interface is the same as the rotation direction, so as to avoid blocking material; if the screen mesh is tapered, due to the small hole end Usually there is a small amount of burrs. To facilitate discharge, the large holes should be installed outward. 3. The pulverizer with the air pump can also be controlled by adjusting the size of the damper when adjusting the particle size.
