The spiral structure design of variable diameter and variable pitch is adopted, and different compression ratios are used for different slurries.During the movement of the slurry, the volume gradually decreases, and the extruded filtrate flows to the filtrate tank through the filter plates of different pressing zones.Adjust the pressure of the back pressure device at the discharge end and the rotational speed of the screw shaft to control the pulp concentration and output.According to different structural designs, it is suitable for black liquor extraction and concentration of chemical pulp, chemical pulp, waste paper pulp and other pulp.
