Matlab was also used to develop a mathematical model for the ball wear rate and its cost effectiveness basing on surface theory and volume theory From the experimental results the Cr C ratio in the chemical composition 18 2 gave the required hardness Also water quenched grinding balls gave the required hardness
Improved wear resistant materials can be installed for grinding media especially in ball mills Grinding media are usually selected according to the wear characteristics of the material Increases in the ball charge distribution and surface hardness of grinding media and wear resistant mill linings have shown a potential for nbsp
This ensures size reduction of the large particles with simultaneous grinding of the smaller particles Charge Level Maintain the CoorsTek media charge at 48 55 of total mill volume in batchtype mills and 38 42 in continuous mills In most cases production efficiency decreases and wear of the media increases nbsp
