Description

TECHNICAL FIELD

[0001] The utility model relates to feed grinding technical field, especially relates to a kind of grinding equipment for high-efficiency comminution of feed raw materials. BACKGROUND

[0002] The comminution of feed raw materials plays a key role in the feed production process, directly affecting the quality and production efficiency of feed. There are many types of feed raw materials, including grains, beans, hay and various mineral additives, etc. The physical properties of these raw materials differ significantly, and this puts forward diversified requirements for grinding equipment.

[0003] In the feed raw material grinding equipment, the common structure contains the following several main parts:

[0004] 1. Feeding device: responsible for conveying raw materials to the grinding chamber, the rationality of its design is crucial for the stable supply of raw materials.

[0005] 2. Grinding chamber: as the core area, its inner wall material is mostly made of high-strength wear-resistant material, such as high manganese steel or tungsten carbide coating, to withstand the intense friction and impact during grinding. The internal stirring device is used to promote the thorough mixing of raw materials and grinding media.

[0006] 3. Grinding media: including stainless steel, ceramic and other materials such as grinding balls or grinding rods, which achieve comminution through interaction with raw materials.

[0007] 4. Power system: usually powered by a motor, and driven by belt drive, gear drive or direct drive to drive the grinding-related components to operate.

[0008] Currently, in order to improve the grinding effect and production efficiency of feed raw materials, many manufacturers have adopted different technical means and equipment structures. Some manufacturers have designed special-shaped grinding tracks inside the grinding chamber, trying to guide the grinding media and raw materials to form more complex motion trajectories to enhance the grinding effect. Some manufacturers optimize the ratio and size of grinding media to adapt to the grinding needs of different raw materials. Some manufacturers install a pre-crushing structure on the feeding device to preliminarily crush larger particles of raw materials for subsequent grinding.

[0009] However, the prior art still has some deficiencies. In the grinding process, most of the conventional grinding structures have limited grinding efficiency, which easily leads to uneven grinding. Commonly, the blade is used for crushing. If the gap of the blade design is small or the design is complex, the crushed material may be left between the blades and is difficult to remove. If the blade material is soft or easy to wear, metal chips may be generated during use. In terms of feeding, the size of the feeding port of many devices is fixed and cannot be flexibly adjusted according to the characteristics (such as particle size, flowability, bulk density, etc.) of the raw materials and different production formula requirements. This may cause the raw materials to be discharged unevenly. The present application proposes a feed raw material efficient grinding device to effectively solve the problems of uneven grinding and inflexible feeding in the prior art, improve the grinding efficiency and quality of the feed raw materials, and meet the diversified needs of feed production.
