# The Calculate The Reduction Ratio Of Ball Mill

### screen capacity calculation

the rounder the rock, and the greater the ratio of rock size to opening, the faster the rock moves from the feed end of the screen to the discharge end. the faster the rock is moving the less likely it is to pass through an opening. the flatter the incline angle the easier it is for the rock to pass through an opening. flat screens have a constant
