Ball Charge and Grinding Efficiency (22 replies) Low ball ratio is not the same as low mill density. If the slurry density falls below 80% then the slurry will not adhere to the balls and there will be no further abrasion grinding (only impact grinding). Reducing the ball charge will reduce the grinding capacity,

#### Effect of lifters and mill speed on particle behaviour
