Efficient ball mill for powder metallurgy

Abstract

The efficient ball mill comprises an operation main body, the operation main body comprises a connecting support piece, a driving assembly arranged on the outer side of the connecting support piece and a ball milling assembly arranged in the connecting support piece, and the ball milling assembly comprises a charging barrel mechanism and a driving assembly arranged in the connecting support piece; the invention relates to the technical field of powder metallurgy. The efficient ball mill for powder metallurgy can effectively solve the problems that in the prior art, crushing media contained in the barrel and materials continuously entering the barrel are separated from the inner wall of the barrel to be cast to fall or roll down when rotating along with the barrel to a certain height under the action of centrifugal force and friction force, and the crushing efficiency is high. The problems that materials are crushed under the action of impact force and continue to run in the ball mill, crushing media slide mutually to grind the materials, the size of the crushing media determines the fineness of the discharged materials, the crushing media prepared in an existing ball mill are constant, the grinding efficiency is low, and the fineness of the discharged materials is difficult to further improve are solved.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy, in particular to a high-efficiency ball mill for powder metallurgy. Background technique [0002] Powder metallurgy is a process technology for producing metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, forming and sintering to manufacture metal materials, composite materials and various types of products. The powder metallurgy method has similarities with the production of ceramics, and both belong to the powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solve the problems of new materials and plays a pivotal role in the development of new materials. [0003] The ball mill is mainly composed of a cylinder, a hollow shaft, a large gear, a pinion, a reducer an...

AI Technical Summary

Problems solved by technology

[0005]Aiming at the above-mentioned shortcomings existing in the prior art, the present invention provides a high-efficiency ball mill for powder metallurgy, which can effectively solve the problems in the prior art that The internal crushing medium and the materials continuously entering the inside of the cylinder, under the action of centrifugal force and friction, will break away from the inner wall of the cylinder and fall or roll down when the cylinder rotates to a certain height, and the materials will be crushed under the impact force and Continue to run in the ball mill, the mutual sliding of the crushing media will grind the materials, but the size of the crushing media determines the fineness of the output, the existing ball mills are equipped with constant crushing media, the grinding efficiency is low, and it is difficult to further improve the fineness of the output. degree of question
