application: zdr series disc type disperser is used for handling the impurities in the raw material of waste paper, such as hot melt material, adhesive material, asphalt and ink etc. under the conditions of high temperature and high consistency, the visible fine impurities, which cannot be removed in the preceding procedure, will be intensively peeled off and dispersed into invisible tiny granules by the fibrillating fluted disc whose control accuracy is 0.01mm. and by fibrillating fibers, pulpâ??s beating degree, paper sheetâ??s formation and breaking length can be improved by intensifying the even mixture of bleaching chemicals with pulp. all of these results in enhancing the pulpâ??s whiteness. design features: zdr series disc type disperser consists of fibrillating fluted disperser, body, driving unit, main control hydraulic system, displacement sensing unit and lubricating system, etc. in the heating screw, the pulp with the consistency of 25~30% is heated to 80~130â??and mixed with the chemicals. then the pulp enters the feeding screw in the form of round particles. through the screw-rotating disc in the disperser, the pulp is extruded into the 0.1~0.5mm gap between the fibrillating fluted moving disc and fixing one, and then outwards from the center the pulp goes through the crushing, jordaning and refining zones between the fluted discs. between the fibrillating fluted discs, the pulp will be mechanically and physically acted intensively and evenly rubbed and softened so that the hot melt material, adhesive material and ink etc. will be peeled off from fibers and dispersed into invisible tiny granules and the pulp will be mixed with the chemicals evenly. disperserâ??s main control hydraulic system, displacement sensing unit and electrical system implement automatic detection of the gap of the fibrillating fluted discs with the control accuracy of 0.01mm, make the gap come back to the normal value so that disperserâ??s technical performances will be assured. dispersing specific energy is controlled by the electrical-hydraulic system with the accuracy of 0.01mm, so the best quality stability will be ensured. zdr series disc type disperser helps in improving the process properties of fiber and enhancing the strengths of pulp. after treatment, the pulp is visually even. zdr series disc type disperser helps in significantly reducing power consumption to 35~40kw/h per ton of pulp.
