This equipment is the latest generation of patented dehydration equipment developed and produced by our company by introducing, digesting and absorbing advanced Finnish technology. It has large processing capacity and high dehydration efficiency (the pulp concentration can be directly increased from 0.8-3% to more than 28-35%). Low Energy and other advantages, it not only solves the problem of material running out when the traditional ordinary double-mesh filter press dehydrates raw materials, but also solves the problem of low material pressure at both ends of the mesh. Since the latest model has a pre-dewatering mesh case , the natural gravity dewatering area of sludge is lengthened, and the mesh is not squeezed, and the mesh is not easily blocked by fibers and sludge. Therefore, compared with traditional filter presses: the consumption of mesh and amide is reduced by more than 10-30%, and it has a simple structure and easy installation. It is an ideal product for sludge press filtering, black liquor extraction or slurry concentration.
