After striking each other, a vortex motion is formed between the turntable and the casing, causing multiple blows, friction, and pulverization, and straight discharge from the lower portion. A closed loop is formed multiple times, controlled by a screening device to achieve the desired particle size.

In the metallurgical, mining, chemical, cement and other industrial sectors, a large number of raw materials and recycled waste are processed every year with grinding mill. For example, in the concentrator, in order to achieve the separation of the useful minerals in the ore, it is necessary to crush the ore to the particle size required by the grinding process.

It is necessary to crush the raw material with a pulverizing machine to the particle size required for the next operation. In coking plants, sinter plants, ceramics factories, glass industry, powder metallurgy and other departments, the crushing machinery must be used to crush the raw materials to the particle size required for the next operation.
