The Grinding medium of Cement Ball mill

Grinding media are the grinding media of cement ball mill, which is used for crushing and grinding raw materials. They are the key pieces of equipment for grinding crushed materials. Generally the size of steel ball is between 40-150mm. The quality and characteristics of grinding medium have close relationships to the working efficiency, production capacity and so on of cement ball mill. This article will make you have a complete understanding of the grinding medium of cement ball mill.

Size: the size of grinding medium is generally between 40-150mm so that it can be filled in with different proportion. However, the smaller the media particles, the smaller the particle size of the final product. At the same time, the grinding media particles should be substantially larger than the largest pieces of material to be ground.

Hardness: grinding medium must be durable enough to grind the material. But they also wears down the tumbler at a fast pace at the same time.

Materials: Various grinding applications have special requirements. For example, grinding medium cannot affect the color of the finished product. Grinding medium cannot react with the material being ground. In addition, the grinding chamber can also be filled with an inert shield gas that does not react with the raw materials to prevent oxidation or explosive reactions that could occur with ambient air inside the cement ball mill.

Density: The media should be denser than the material being ground, so that grinding media cannot float on top of the raw materials.
