The industrial pin mill (also known as a universal mill, turbo mill, and impact mill) is a one pass grinding equipment ideal for achieving the micronization of bulk materials and powdered products. Common applications involve the fine grinding of sugar, salt, sodium bicarb, etc. The average achievable particle size range of the pin mill is around a d50 of 80 microns.

The grinding process of the ceramic raw material by the mill is more complicated than the single-grain material ball milling process. It is a composite of finely divided single particles of material, and the crack propagation on the surface of the material particles and the appearance of new cracks will change due to the interaction of each crack.

Raw mill is also called cement raw mill, similar to cement ball mill, it is an important cement milling equipment used in the cement production process. Raw mill is mainly used for grinding cement raw meal in the cement factory production process.
