In the production process of feed processing machinery, the crushing process is a very critical process. As far as the current production is concerned, depending on the number of times of raw material pulverization, it can be mainly divided into a pulverization process and a secondary pulverization process. One of the pulverization processes is simple and the equipment investment is small, but the disadvantage is that the processing result of the pulverized material may have uneven grain size and high power consumption.

Another comminution process can make up for this deficiency. With this process, the finished product processed by the feed processing machine has the same particle size, high output and low energy consumption, but its equipment investment is large. Therefore, most feed mills currently use a single crushing process. In compound feed, pellets generally account for 60%-70%. When the pulverizer is selected, the production capacity of the pulverizer is generally greater than that of the feed mill, and the surplus time is used for maintenance and replacement of wearing parts.

It should be noted that in order to complete the production work more quickly, it is generally required to prepare at least two warehouses to be crushed in advance. If the variety of pellets is large, it should be increased appropriately. Under normal circumstances, its storage capacity should not be less than 2-4 hours of feed processing machinery crusher to reduce the number of starts of crushing and caring.

In addition, it is necessary to consider that in the operation of feed processing machinery, the feeding device used to crush the pellets is very important. For small feed mills with low automation, the manual gate is often used to control the feeding amount. Large-scale feed mills often use impeller-type or spiral-type automatic control feeders, whose speed is adjustable, which can change the feeding amount. The more advanced control method uses a negative feedback circuit to control the feeder through the current of the pulverizer. Feed amount.

At the same time, in the production system, it is also necessary to match the matching ingredient warehouse. In general, it is necessary to provide a conveying device at the top of the batching bin. The conveying device includes two kinds of a rotating distributor and a screw conveyor. The main function is to accurately distribute the crushed material and the auxiliary material without crushing the required space. Higher, but effectively avoid cross-contamination.
