Abstract
A pressure screen for separating a liquid mixture is disclosed, comprising a screen housing forming a cylindrical screen chamber, and an inlet housing directly connected to the screen housing and forming a cylindrical inlet chamber, the diameter of which is less than the diameter of the screen chamber. An inlet member is positioned on the inlet chamber for supplying a suspension to be separated substantially tangentially into the inlet chamber and an outlet member is positioned on the inlet chamber for discharging coarse contaminants from the inlet chamber, whereby the scrap particles are prevented from entering the screen chamber.
