[0002] Cereals mainly refer to Gramineae crops and their seeds, including rice, wheat, corn, millet and other grains, such as sorghum, wild rice, oats, coix rice, etc. The nutrients they contain are mainly carbohydrates, mainly starch, followed by protein. In the breeding industry, cereals are usually used to produce feed.

[0003] In the process of producing grain feed, it is generally necessary to crush the grains and then form a composite feed with a variety of different raw materials. The crushing process mostly adopts a principle similar to that of a wall breaker, using a rotating blade to cut and crush the grains. When the grain fragments meet the particle diameter requirements, they will leave the crushing area through the filter. The filter will be set below the crushing area, and the grains mainly leave by their own weight. However, the large particles produced in the crushing process are easy to accumulate in the mesh of the filter, resulting in poor material discharge during the filtration process.
