Background
The ball mill comprises a cylinder and a grinding body, when the ball mill cylinder rotates, the grinding body is attached to a cylinder lining plate and taken away by the cylinder due to the action of inertia, centrifugal force and friction force, when the ball mill cylinder is taken to a certain height, the ball mill is thrown down due to the gravity action of the ball mill cylinder, and the thrown-down grinding body crushes materials under the action of gravity and impact force to realize material grinding. The ball mill has simple structure and good equipment reliability, and is widely applied to industries such as building materials, mineral separation, metallurgy, electric power, medicine, food, chemical industry and the like. The ball mill can be divided into a dry type and a wet type according to different grinding environments; according to different transmission modes, the transmission mode can be divided into a center transmission mode and an edge transmission mode.
When the existing ball mill conveys materials into the cylinder, when the feeding amount is large, the flow rate of the materials is high, so that no materials stay at the grinding end of the ball mill, namely, the materials are washed, the ball mill bears uneven impact load, and part of steel balls do not have a grinding effect on the materials when moving, so that the grinding efficiency is low; when the feeding amount is small, because the gas in the mill is usually kept at micro negative pressure, the gas flow is blocked in the process of moving the steel balls and the materials, so that the ash emission problem, namely the material returning phenomenon, is generated at the milling end of the ball mill, and the green production is influenced.
