Ball Mill Charge Grinding Classification Circuits Know More The ball charge is determined by the operator targeting the balance between grind and throughput the higher the ball charge the more aggressive the milling becom With softer oxide ores lower ball charges are usual however the harder sulphides does need more media energies to meet the P80 target and an acceptable throughput For overflow ball mills the charge should not exceed 45 of the mill volume For grate discharge mills the charge should occupy about 50 of the mill volume Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge He and the radius of the mill R ie
