- Ball Size Effect On Grinding Mill

Jul 18 2013 The makeup balls are 80 mm forged alloy steel balls and the average ball consumption is 750 g t 1 ore ground. In order to optimise ball size distribution inside the mill based on the previous investigation instead of using only 80 mm makeup balls a combination of 80 and 60 mm 75 and 25 wt- ball charge was used in one of the grinding lines.
