Introduction of Ball Mill: Ball mill is an efficient tool for grinding many materials into fine powder. The Ball Mill is used to grind many kinds of mine and other materials or to select the mine. Our ball mill can grind ore or other materials that can be grinded either by wet process or by dry process.

Comparison of energy efficiency between ball mills and ...

At product sizes finer than 80% passing 75 μm the efficiency of ball mill grinding rapidly decreases. The practical limit to ball mill product fineness is considered to be 40–45 μm (Gao and Weller 1994). Although ball mills can still be found in the regrind circuits in a number of mineral processing plants their energy consumption is high and size reduction efficiency is low.
