ABSTRACT:
A sieve for powder. The sieve has a housing in which a transverse screen is mounted to divide the housing into upper and lower chambers. Air under pressure carries powder into a cyclone stack mounted on top of the housing from which it is directed onto the screen. A vibrator is connected to the screen to vibrate and thus to assist in the sieving operation. The screen is downwardly inclined and overlying its lower end an inspection cover is mounted in the housing to permit access to the screen for removal for the material which does not pass through the screen.
