[0002] Feed is a general term for food for raising animals, mainly referring to food for agricultural or animal husbandry animals. The main raw materials of feed are soybeans, corn, fish meal, amino acids, additives, whey powder, oil, meat and bone meal, grains and sorghum, etc. In the process of feed processing and production, the granular feed after granulation often has different particle sizes. Therefore, it is necessary to screen the granular feed according to different feed usage methods to obtain feed particles of the required particle size. Therefore, in the process of feed production, a screening mechanism is needed to screen the feed particles.

The existing screening devices mostly use single-structure screening, which cannot meet high screening requirements and will cause impurities to be mixed in the feed, reducing the screening efficiency. For this reason, we propose a feed screening collector with secondary screening function. Utility Model Content
