摘要： 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.

摘要： A thickener for concentrating fiber suspensions is disclosed including a housing, a rotor arranged on the housing, a screen attached to the rotor for separating the fiber suspension into a first fraction passing through the screen substantially containing only fibers and a fraction not passing through the screen and containing coarse undesired particles, a stationary thickener surrounding the rotor and provided with through holes and supply conduits for supplying the first fraction to the stationary thickener for separating that fraction into a fraction passing through the holes in the stationary thickener and a separate fraction not passing through the holes in the stationary thickener. The through holes are dimensioned such that substantially only liquid is permitted to pass through the stationary thickener and the fraction which does not pass through the through holes comprises the thickened fiber pulp free of the undesired coarse particles.
