Pressure screen and method for dilution for a pressure screen

Abstract

A method for dilution for a pressure screen comprising a rotor rotating inside a screen a distance to the screen, includes supplying feeding stock into a screening zone formed in the spacing between the rotor and the screen with some of the feeding stock passing through the screen into an accept area to become accept, and the remaining feeding stock discharged into a reject area as reject flow. The amount of the dilution water added into the reject flow is 0.8 to 3.5 times the amount of the reject flow by volume. Additionally, a pressure screen comprises a dilution water adding apparatus adapted to add dilution water directly into the reject area of the pressure screen, wherein the amount of the dilution water added into the reject flow is 0.8 to 3.5 times of the amount of the reject flow by volume.
