Vertical Roller Mills: Vertical roller mills have gained popularity in recent years due to their energy - saving and high - efficiency characteristics. In a vertical roller mill, the limestone is ground between rotating rollers and a stationary grinding table. The material is fed onto the table, and the rollers apply pressure to grind it.
These mills can achieve a high degree of fineness in the ground limestone powder and are capable of processing large volumes of material continuously. They are particularly well - suited for large - scale industrial applications, such as in large - scale cement manufacturing plants, where they can significantly reduce energy consumption compared to traditional grinding methods.

Jet Mills: Jet mills use high - velocity gas jets (usually compressed air or inert gases) to accelerate and collide limestone particles, resulting in fine grinding. The gas jets carry the limestone particles into a grinding chamber where they collide with each other or against a target surface. Jet mills are capable of producing extremely fine limestone powders, often in the sub - micron range. They are mainly used in industries where high - purity and ultra - fine limestone powders are required, such as in the pharmaceutical, cosmetic, and high - tech materials industries.
