Double-screw Extrusion Pulp Machine

The problem of the wastewater treatment of our paper-making manufactures has attracted more and more attention from the government and various social circles. Therefore, the problems for all the colleagues of the paper-making industry to consider are how to reduce the emission of wastewater and make the emission of wastewater reach the standard. The technicians of our plant absorb the advantages of the products in the same industry and develop ZSL double-screw squeezer, the new generation equipment of water treatment developed together with the scientific and research institute. It depends on the extrusion effect to achieve the excretion of the black liquor between fibers by the medium, which shortens bleaching duration and times and achieves the objective of saving the water resources. Moreover, ZSJ is the continuous washing equipment in the process of pulping and is able to achieve the extrusion of the black liquor with high concentration to supply alkali for the recycle production while fully washing the slurry. Meanwhile, it can be used for the extrusion of the chemical medical solution in the process of wastepaper deinking to facilitate bleaching. The machine owns small occupied area and convenient operation and is suitable for the slurry of varied raw materials with ideal effects. Moreover, the extrusion pulp machine owns less water consumption for washing and lower power consumption and its effects will better when several sets of machines are connected in series for the countercurrent washing.
