Background

Crushing is a necessary condition for improving the quality of the feed, and is one of necessary means for reasonably utilizing the feed. The crushing of the feed has obvious influence on the digestibility of the feed and the production performance of animals, and also has important influence on the processing process and the product quality of the feed. The proper crushing granularity can obviously improve the conversion rate of the feed, reduce the excretion of animal wastes, improve the production performance of animals, and is beneficial to mixing, tempering, granulating, puffing and the like of the feed. Specifically, the pulverization mainly has the following two aspects: (1) the specific surface area of the feed is increased, and the digestion and utilization rate of animals on the feed is improved. Animal digestive feeds rely primarily on the action of various digestive enzymes. After the feed is crushed, the particles are increased, the total area and the specific surface area are increased, the action area of digestive enzymes on the feed is increased, the digestion speed of animals on the feed is improved, and the digestion utilization rate of the feed can be further improved. (2) The quality of the subsequent procedures such as batching, mixing, granulating and the like is improved, and the working efficiency of the procedures is improved.

The main purpose of the feed mixing is to uniformly mix various raw material components which are matched according to the formula, so that animals can eat the feed with balanced distribution of the components which meet the formula requirements. It is an important link for ensuring the quality of the compound feed and improving the feed reward. Therefore, the feed mixer is also one of the key equipments of the compound feed factory.

However, the feed crushing device and the feed mixing device in the market at present have the problems of high use cost, poor automation degree, low production efficiency, low feed product quality and the like because the feed crushing device and the feed mixing device are required to be independently used, so how to effectively solve the problem becomes a problem to be researched by technicians in the field.
