Description

Technical Field

[0002] Feed is a general term for food for raised animals. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed includes more than ten varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, and feed additives.

[0003] At present, more and more livestock are being raised. With the progress of society, the artificial breeding industry has developed greatly, and the demand for breeding is increasing. The process of feed production includes raw material cleaning, crushing or grinding, mixing, granulation, drying and packaging. When crushing or grinding the raw material, a pulverizer is often needed. The pulverizer is a machine that crushes large-sized solid raw materials to the required size. The pulverizer consists of coarse crushing, fine crushing, wind conveying and other devices. It achieves the purpose of crushing in the form of high-speed impact. It is widely used in the fields of chemical industry, coal, medicinal materials, feed, fertilizer and harmless treatment of urban garbage.

[0004] When using the existing pulverizer to crush the raw materials with high humidity, the machine is prone to sticking, damaging the screen plate. In serious cases, the machine must be shut down for maintenance, affecting production. To solve the above problems, it is usually necessary to dehydrate the raw materials with high humidity first, so it is necessary to equip the dehydration equipment separately; however, in the actual operation process, the dehydration equipment and the pulverizer are separately set, occupying a large area; in addition, after the dehydration operation is completed, the material needs to be manually transferred to the pulverizer for pulverization, the operation process is cumbersome, and it is easy to contaminate the material during the transfer process; in addition, the existing pulverizer lacks a drying function, and it is impossible to dry the pulverized raw materials, which is easy to stick together and affect the discharging process of the pulverizer. Therefore, it is urgent to design a dehydration and pulverization integrated equipment for wet raw materials to solve the above problems. Utility Model Content
