Ball Size as Initial Charge Commercial ball sizes 10 – 150 mm Number size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill Coghill and DeVaney 1937 defined### PERI AutoCharge Mill Grinding Ball Charging System

Each ball feeder/counter system is designed to accept a narrow range of ball diameters and should not be used to charge balls of mixed sizes. Weight-based counter The AutoCharge system’s weight-based counter is suitable for all ball diameters but is particularly applicable to smaller ball sizes 50–80 mm including ball recharge practice involving multiple sizes.### Mill grinding - Wikipedia

Based on their results 42 it is concluded that the rate of amorphization depends strongly on the kinetic energy of the ball-mill charge and this depends on the number of opportunities for the powder particles to be reacted and interdiffused. Increasing the W b:W p ratio accelerates the rate of amorphization which is explained by the increase in the kinetic energy of the ball-mill charge### End Mill Sizes-Chart Of Inch Metric And Micro Diameters
