Ball Mill

Product Introduction

The Ball Mill is the key equipment for re-grinding (fine grinding or pulverizing) materials after they have been primarily crushed. It is an essential and highly versatile grinding mill used across numerous industries for achieving the required product fineness.

Xianglong Machinery’s ball mills are engineered for reliability and efficiency. They are widely used for either dry type or wet type grinding of all kinds of ores and other grindable materials in industries such as cement, silicate products, new building materials, refractory materials, fertilizer, black and non-ferrous metal ore dressing (mining), and glass ceramics production.

Working Principle

The ball mill operates through rotation, causing the grinding media (steel balls) inside the cylindrical shell to cascade and tumble. Material fed into the mill is crushed and ground through impact (balls falling onto the material) and attrition (material rubbing between the balls and against the mill liners).

As the shell rotates, lifter bars inside help lift the balls. Depending on the rotation speed, the balls cascade down, creating the grinding action. The finely ground material is then discharged from the mill through discharge openings, often controlled by a grate or overflow system, depending on whether it’s a wet or dry grinding process.
