SCREEN CAPACITY CALCULATION - VIBFEM

is less than half the size of the wirecloth opening. The higher the percentage of small feed material the greater the screen capacity. The faster the material passes through a screen the more open area there is left to screen the remaining material. A feed material with 40% of the feed being half the opening size or smaller equates to a factor ...
