[0002] Corn, as the king of coarse grain nutrition, can regulate human metabolism, improve immune function, enhance body resistance, remove waste from the body, fight disease and prevent aging. As people pay more attention to health, they gradually realize the nutritional and health functions of corn and other grains, and make better use of this green resource.
[0003] The corn mill consists of a feeding system and a traction-type clutch crushing system. It integrates crushing, grinding and feed processing in one. It can process flour of different specifications and mesh sizes. It has the advantages of simple structure, good processing and installation processability, small size, low noise, easy operation and use, and is not prone to over-torque or flour sticking.
[0004] In the process of processing corn, it is often necessary to use a grinder to grind corn particles to facilitate subsequent processing. However, most of the existing corn grinders only have a grinding structure with a single function. There may be some particles that are not ground well in the ground corn powder particles. These particles do not meet the grinding requirements and need to be filtered and then re-ground. The grinder with a single function cannot achieve both grinding and filtering functions. The corn powder particles can only be filtered and screened after the mill discharges the material, and the particles that do not meet the grinding requirements are poured into the grinder for re-grinding.
