The basic movement state of the grinding body in the ball mill

The main purpose of the wear-resisting steel ball is to use it as a grinding medium in the ball mill and play a role in grinding and crushing. Then, as the direct use object of the wear-resistant steel ball, the working principle and working state of the ball mill are what is needed. Manufacturers understand.

The working principle of the ball mill:
When the mill rotates, the grinding media rotates with the cylinder due to centrifugal force, and when it is brought to a certain height, it falls down due to its own gravity and impacts the material. At the same time, the grinding body has sliding and Rolling, grinds the material. Under the action of grinding media impact and grinding, the material is crushed and ground.

Three basic motion states that can occur in the grinding body:
When the rotation speed is too fast, the grinding body and the material sticking cylinder rotate together with it. In this case, the grinding body does not have any impact and grinding effect on the material.
When the speed in the diarrhea state is too slow, the grinding body and the material are brought to the height of the dynamic friction angle due to the friction force, and then fall down under the action of gravity. In this case, the material has a strong grinding effect, but there is no impact effect, and the crushing effect on the bulk material is not good.
When the speed of the throwing state is moderate, the grinding body is lifted to a certain height and then dropped down near the parabola track. At this time, the grinding body has a greater impact on the material, and the grinding effect is better.
As the main grinding medium of the ball mill, the wear-resisting steel ball directly affects the work efficiency of the ball mill. For this, the manufacturer of the ball mill should select the brand-protected wear-resistant steel ball, such as the high-quality high-chromium ball produced by Ningguo Kaisheng. .
