TECHNICAL FIELD

[0001] The utility model relates to the technical field of feed processing, in particular to a hammer mill for feed processing. BACKGROUND

[0002] Feed processing is a process of making feed suitable for animal consumption by processing a variety of raw materials through a series of processes, which includes receiving and storing raw materials, cleaning and screening, crushing, batching, mixing, granulating, drying and cooling, and packaging and storage, etc. The purpose is to improve the nutritional value, palatability and storability of feed, so as to promote the growth and health of animals. Different animal species and growth stages have different requirements for feed, so feed processing needs to be adjusted and optimized according to different requirements.

[0003] In the process of feed processing, the raw materials need to be crushed, so the hammer mill needs to be used. Although the traditional hammer mill has crushing capacity, it still has some shortcomings, such as poor protection of the hammer. Therefore, the hammer will be damaged during long-term contact with the raw materials, which will affect the crushing effect and service life of the hammer. In addition, the screening effect of the raw materials is not good, so it is difficult to ensure the crushing degree of the raw materials, which will affect the quality of the finished feed. Therefore, a hammer mill for feed processing is proposed to solve the above problems. SUMMARY

[0004] The utility model discloses a hammer mill for feed processing, which has better protection of the hammer, so that the hammer is not damaged during long-term contact with the raw materials, thereby ensuring the crushing effect and service life of the hammer. In addition, the screening effect of the raw materials is better, so it can ensure the crushing degree of the raw materials, thereby providing protection for the quality of the finished feed to solve the problems in the background technology.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] In this invention, the pulverizing chamber provides space for the pulverizing components and the raw materials, while the collecting chamber provides space for the raw materials. The feeding hopper guides the raw materials into the pulverizing chamber, and the hopper cover can seal the hopper when not feeding to prevent other debris from entering the pulverizing chamber and affecting feed quality. The pulverizing components pulverize the raw materials to a suitable size and offer excellent protection for the hammer blades, preventing damage from prolonged contact with the raw materials and ensuring pulverizing effect and service life. The through-slot connects the pulverizing chamber and the collecting chamber, providing a path for the pulverized raw materials.
