Screw Press is used in the pulping and paper making industry to dewatering and concentrate waste paper pulp. It is used in series with the Inclined Screw Thickener to achieve the treatment concentration required by Disperser. This Screw Press is the key equipment in the heat dispersion system of the pulping line of the paper mill. Energy saving, efficient and easy to clean.

Working Principle of The Screw Press

1. The pulp enters the filter basket from the pulp inlet at the upper end of the filter basket, and is continuously dewatered and conveyed to the pulp outlet under the extrusion action of the rotating screw main shaft with a certain compression ratio; The water squeezed out of the pulp passes through the filter basket and enters the water receiving tray, and flows out from the white water outlet.
2. There is a pneumatic cone disc at the spiral discharge, which can control the pulp pressure to adjust the pulp concentration; In order to ensure the consistency of the dewatering inside and outside the pulp layer, there is a sleeve with holes on the main shaft for auxiliary dewatering.
