Abstract
In a multiple deck screening machine, the feed material is divided into separate equal fractions as it falls into parallel vertical channels. Each channel serves a particular screen deck via a chute which diverts the respective fraction from the channel onto the screen. The lower chutes include widened portions that extend laterally from their respective channels into areas which are masked or closed above by overlying upper chutes, in order to provide flow areas onto the respective screens which are wider than the channels that feed them, and thereby provide better flow distribution onto the screens.
