pulping machine---the biggest disperser in China

Applications: ZDR series disc type disperser(pulping machine)is used for handling the impurities in waste paper raw material, such as hot melt material, adhesive material, asphalt and ink etc. Under the condition of high temperature and high consistency, the visible fine impurities, which can not 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, pulps beating degree and paper sheets formation, breaking length will be improve; by intensifying the even mixture of bleaching chemicals with pulp, pulps whiteness will be enhanced. Structure principle: ZDR series disc type disperser consists of fibrillating fluted disperser, body and driving unit, main control hydraulic system, displacement sensing unit and lubricating system etc. In the heating screw, the pulp with 25 30% consistency is heated to 80130 and mixed with the chemicals. Then the pulp enters the feed screw in the form of roundel. Through the screw-rotating disc in the disperser, the pulp is extruded into the 0.10.5mm 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 disc. 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. Dispersers main control hydraulic system, location 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 dispersers technical performances will be ensured. ·Dispersing specific energy is controlled by the electrical-hydraulic system with the accuracy of 0.01mm, so the best quality stability will be ensured. ·Improving the process properties of fiber, enhancing the strengths of pulp. ·After treatment, the pulp is visually even. ·Significantly reducing power consumption to 3540KW/h per ton pulp.
