First, like ball mills such as energy-saving ball mills and cement ball mills, planetary ball mills are also composed of a cylinder, a liner, a feeder, a discharger, a hollow shaft, a bearing, a transmission, and a lubrication system. The difference is that the planetary ball mill is smaller than other ball mills, and it is widely used in product testing and in the laboratories of major universities.
In the planetary ball mill, the cylinder rotates around the horizontal axis at a certain rotational speed. The medium and raw materials contained in the cylinder are separated by the centrifugal force and the friction force. When the whole body reaches a certain height, when their own gravity is greater than the centrifugal force, they are separated. The inner wall of the cylinder is thrown down or rolled down. At the time of the fall, the impact is generated and the ore is crushed. Of course, during the rotation of the cylinder, the sliding movement of the grinding media to each other also rubs against the raw materials, causing a grinding action.
Like other ball mills, planetary ball mills are also used for fine grinding operations and sometimes for rough grinding operations. It is also used to grind high hardness ore, coal or other grindable materials where necessary.
Although the planetary ball mill is small, there are many components on the ball mill. For other ball mills, we can also learn from one another in this way, which is an indispensable course in mineral processing.
