Description

Technical Field

[0001] The utility model relates to the technical field of mineral processing, in particular to a ball mill for producing lithium sulfate solution. Background Art

[0002] In the production process of lithium sulfate solution, the ore containing lithium is ground by a ball mill. The ball mill is composed of a motor, a reducer, a horizontal cylinder and other parts. The cylinder is equipped with a grinding body, which is fixed to the cylinder by a steel lining. The grinding body is generally a steel ball and is loaded into the cylinder according to different diameters and a certain proportion. The material is loaded into the cylinder from the feeding end of the ball mill. When the cylinder of the ball mill rotates, the grinding body is attached to the cylinder lining due to inertia, centrifugal force and friction, and is carried away by the cylinder. When it is brought to a certain height, it is thrown down due to its own gravity. The falling grinding body crushes the material in the cylinder like a projectile;

A ball mill of the utility model can make the powdered material in the cylinder quickly pass through the filter screen and be discharged into the discharge. The above-mentioned prior art scheme has the following shortcomings: a filter screen is installed at the discharge port of the ball mill. Since the discharge port is small, it is easy to be blocked during the discharge, affecting the normal discharge effect. Therefore, it is necessary to design a ball mill for the production of lithium sulfate solution to solve the above problems. Utility Model Content
