Grinding device for manufacturing metal powder and working method thereof

Abstract

The invention discloses a grinding device for manufacturing metal powder. The grinding device comprises a grinding cylinder, a cover body and a conical cylinder bottom, wherein a rotating shaft is arranged in the grinding cylinder, the rotating shaft is connected with a driving motor through a transmission device, a plurality of grinding units are fixedly arranged on the part, located in the grinding cylinder, of the rotating shaft, each grinding unit comprises a grinding plate and a grinding ring, distribution structures are arranged on the upper surfaces of the grinding plates, a plurality of containing grooves are formed in the outer edges of the grinding plates, each containing groove is internally provided with one grinding ring, and grinding gaps are formed between the outer circumferential surface of the grinding rings and the inner wall of the grinding cylinder. The invention further discloses a working method of the grinding device for manufacturing the metal powder. The device has the beneficial effects that the automatic operation is realized, the continuous production can be realized, the operation is simple and convenient, the production efficiency is improved, and thelabor intensity of operators is reduced; consumable parts are easy to replace, and the maintenance cost is low; an assembly structure is simple, and disassembly and assembly are convenient; and through matched adoption of the grinding plates of different specifications, the grinding particle size of each grinding plate can be adjusted, the grinding efficiency is improved, the requirements of different working conditions can be met, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of metal powder processing, in particular to a grinding device for manufacturing metal powder. Background technique [0002] Metal powder refers to a group of metal particles with a size less than 1mm, including single metal powder, alloy powder and certain refractory compound powders with metallic properties, and is the main raw material for powder metallurgy. In the metal powder grinding process, the mills used to crush the powder are usually ball mills, that is, rotating cylindrical mills filled with crushing elements. Very long times are required to obtain a homogeneous powder mixture as well as to achieve the target particle size, milling times of 40 hours are not uncommon. [0003] Chinese patent CN108772768A discloses a metal small piece grinding device, including a hydraulic cylinder, a support table, a rotating motor, a diamond-shaped grinding head, a hollow conical cavity, and a powder pumping dev...

AI Technical Summary

Problems solved by technology

This technical solution also has the problem that only materials that meet the particle size of the finished product are allowed to fall during the blanking process, which also makes the upper grinding part highly usable, while the lower grinding part is less usable. When some grinding parts are damaged, Only the entire grinding part can be replaced as a whole, which increases the cost of use, and also affects the blanking speed and processing efficiency. Although the pulling mechanism increases the discharge gap, it has no effect on the above-mentioned blanking speed, and also affects the above-mentioned other technologies. The problem has not improved
