在饲料加工过程中，原料粉碎是第一步，也是重要的一步。原料粉碎的粗细与否不但影响后续工序，如混合、制粒等过程，而且对饵料系数的影响也很大，原料的粉碎细度越细，往往可以降低饵料系数，反之，原料粉碎细度粗，饵料系数往往会比设计标准高。这是因为，鱼类消化道中无咀
In feed processing, raw material crushing is the first step, but also an important step. Whether the thickness of the raw material is crushed or not affects not only the subsequent processes such as mixing and granulation, but also the influence on the feed coefficient. The fineness of the raw material is fine, and the feed coefficient can often be reduced. On the contrary, , Bait coefficients tend to be higher than design standards. This is because there is no mouth in the digestive tract of fish
