在家禽饲养业中,为了粉碎贝壳、颗粒状草粉和其他饲料,目前普遍使用带有通用饲料粉碎机上主动工作部件的各种粉碎机。但是,这些粉碎机只能将块状饲料加工成粉状,而粉状饲料不易被家禽食用。辊式粉碎机的机架10(见图)、筛架和电动机1与种子清选机类似。用10号槽钢制成的辅助机架11焊接在机架10上,并用 In the poultry industry, various crushers with active working parts on general purpose feed mills are now commonly used to crush seashells, granular grass powder and other feeds. However, these shredders can only process lumpy feeds into powdery forms, whereas powdered feeds are less likely to be consumed by poultry. The frame 10 of the roller mill (see the figure), the screen frame and the motor 1 are similar to the seed cleaner. Auxiliary racks 11 made of 10-gauge steel are welded to the frame 10 for use
