Problems solved by technology

The reason for this phenomenon is that the finer the particles, the fewer defects such as microcracks on the particles, it is not easy to form stress concentration, and the finer particles are more difficult to crush. The load of the ball mill fluctuates greatly during operation, and the load of the ball mill is very heavy when it is started. The ball mill can be moved to any position by moving, which requires the inverter to have a large torque at low frequency

Abstract

The invention discloses a mine ball grinding mill. The mine ball grinding mill comprises a cylinder body, a lining plate, a feeding device, a discharging device, a rotary shaft and a transmission device, wherein the feeding device is mounted at the front end of the cylinder body; the cylinder body is internally provided with the lining plate; the discharging device is mounted at the rear end of the cylinder body; the transmission device drives the cylinder body to rotate through the rotary shaft. In the manner, the service lives of a ball milling body and a motor of the mine ball grinding mill can be prolonged and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a mining ball mill. Background technique [0002] In the prior art, the crushing effect of the ball mill on the material is mainly the impact and grinding of the material by the grinding body. When the material is ground by the intermittent ball mill, the content of coarse particles decreases rapidly at the beginning, and the grinding speed of the material is very fast. As the grinding process progresses, the grinding speed gradually slows down, and then becomes slower and slower. The reason for this phenomenon is that the finer the particles, the fewer defects such as microcracks on the particles, it is not easy to form stress concentration, and the finer particles are more difficult to crush. The load of the ball mill fluctuates greatly during operation, and the load of the ball mill is very heavy when it is started. The ball mill can be moved to any position by simpl...
