Highlights

Variable- diameter and variable pitch spiral The stock is pressed in a slowly reducing space, so that the dewatering of the stock layer is atmost same.
Low rotation speed: When there are bulky or hard substances (such as iron ware) in the stock, the impurities will be automatically extruded into the space between helical blades, so as to avoid the damages to the equipment.
Adjustable outlet consistency: The screw shaft with high compression ratio, to high concentration of stock and outlet consistency can be adjusted with pneumatic or manual plunger as per operator's demands.
Special structure to prevent slipping of stock and to keep steady the outlet consistency
Closed design to prevent the overflow off-flavor
Completely mechanical extruding dewatering withoug special requirements of installation height
Highly dewatering efficency to deprive over 85% black liqure in the stock

Structure

It is composed of driving unit, screw shaft and screen cylinder.
Driving unit: Electric motor, Gearbox and Coupler
Screw Shaft: The first section in contact with stock is the converyer screw and the middle part is the conical variable diameter variable-pitch to increase the compression ratio the filter liquor extraction precentage and consistency of stock. At the end of the section a blade-interruption is termed as "interception section" to prevent the impacts on outlet consistency due to uneven inlet consistency. The later part is converyer screw section.
Screen Cylinder: it is composed of four sections for input filting compression and outputs, each section in the steel frame structure and spuuorted eith steel skeleton. the outside of filter is a screen plate with big holes to protect screen plate.
