[0002] Feed is the general term for the food of all animals raised by people, and mainly refers to the food of animals raised in agriculture or animal husbandry. The grinding of feed raw materials is a very important link in feed processing. Through grinding, the total surface area of raw material particles per unit mass can be increased, the solubility of feed nutrients in animal digestive fluids can be increased, and the digestibility of animals can be improved. At the same time, the size of the ground raw material particles has a very important influence on the difficulty of subsequent processes and the quality of finished products.
