vibrating screen efficiency calculation theory

Vibratory Screens | McLanahan

Today's screens come in widths from 4’-12' wide and from 8’-32' long. Screens are normally sized so that the length is 2.5 times the width. The width of a screen will determine the maximum carrying capacity of the screen deck, while the length of the screen will determine the overall efficiency of the deck.
