Ball Mill Charge

Ball Mill Charge 1 reply The crop load of ball mill It =ore mill medium water But usually it was used in a percentage formation So how to calculate this percentage I know this is really a basic question but it puzzled me for most books and papers just use it but nor explain it The ball charge and ore charge volume is a variable...

ball charge grinding mill

Ball Mill Charge Grinding Classification Circuits 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 becomes 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 These comments...

3 size reduction

21-09-2019 0183 32 The load of balls in a ball or tube mill is normally such that when the mill is stopped the balls occupy about one-half the volume of the mill The void fraction in the mass of balls when at rest is typically 040 When the mill is rotated the balls are picked up by the mill wall and carried nearly to the top where they break contact with the wall and fall to the bottom to be picked up...
