ZSLX type double helix crowded pulp Machine is mainly used for chemical pulping black liquor of high temperature, High consistency, efficient extraction, especially rice and wheat straw pulping Black liquor extraction. the system tightness is good, the slurry heat loss is Small, black liquor extraction rate is high, the extraction of black liquor with High temperature and concentration, for energy-saving efficiency of black liquor Treatment process such as alkali recovery to create favorable conditions. At the Same time, the higher black extraction rate reduces the pollution degree of the Medium water and reduces the processing load of the pulping water. Its working Process is the size of discharge storehouse of discharging mouth or high Concentration hydrapulper pulp out of the mouth into the double helix crowded Pulp machine feeding port, through the rotation of the double helix axis, slurry from one end to the other end. as a result of the double helix axis pitch in the Process from large to small, in the process of the forward movement of the Slurry in the machine by increasing the extrusion pressure, forcing the black Liquor will be squeezed out and is discharged by the filter hole, extraction of Black liquor of the pulp concentration of 38% or more, and the discharging mouth Eduction.

the equipment has simple structure, small Footprint, convenient operation and reliable operation. It is the ideal Equipment for the extraction of black liquor of pulp and paper mill.

this machine is mainly composed of screw Shaft, stand, inlet, filter plate, reducer, coupling, speed regulating motor and so on.

this machine is mainly used for the Extraction of chemical or semi-chemical slurry of wood, bamboo, bagasse, straw, Wheat grass and reed, etc.
