With advances in technology and continual changes in consumer tastes, the food industry is continually developing innovations. Among them, the pulverizing technology is widely used in the food industry as a basic processing means. The crushing equipment not only can refine the food raw material particles and improve the surface area of the food raw material particles so as to accelerate the release and absorption of nutrient components, but also can improve the mouthfeel and texture of the food and enhance the packaging and transportation properties of the food.

For corn grain processing, two grinding modes currently exist, namely, artificial stone grinding and mechanical crushing grinding, and the artificial grinding has the advantages of high nutritive value, good taste and the like, but is gradually replaced by the grinding mode of mechanical crushing due to higher labor cost and low yield; however, the mechanical pulverizer directly pulverizes corn grains at high temperature and high speed, which may destroy the nutritional ingredients in the corn, so that the taste is inferior to that of stone-milled corn powder, and meanwhile, metal impurities are introduced during the grinding process due to the fact that the working process is accompanied by machine vibration, thereby affecting the food safety; therefore, how to make the ground corn have good food quality on the premise of lower cost is a problem to be solved.
