screen capacity calculation - vibfem,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.screening theory and practice - triple/s dynamics,screen, circular or reciprocating, or with a vertical component, or it may be a vibration applied directly to the screen wires. 3 in the example above, the particles in the fraction smaller than 1/8” that reach the screen surface have a chance of passing an opening that is expressed by.
