Disc Disperser for Paper Mill Pulping Making Equipment

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 gran
ules by the fibrillating fluted disc whose control accuracy is 0. 01mm. And by fibrillating fibers, pulp's beating degree,paper sheet's 
formation and breaking length can be improved by intensifying the even mixture of bleaching chemicals with Pulp.

Design Features:
ZDR series disc 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 
80-130 ° C 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 ftuted 
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 wilt be mixed with the chemicals evenly. Disperser's main control hydraulic system, position sensitive device 
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 disperser's technical performances will be assured. Dispersing specific energy 
is controlled by the electrical-hydraulic system with the accuracy of 0. 01mm, so that the best stability of quality will be ensured. ZDR 
series disc 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 disperser helps in significantly reducing power consumption to 35-40KW/h per ton of pulp. Function 
Advantages-Driven by Single hydraulic cylinder.

Advantages-Driven by Single Hydraulic Cylinder

Single hydraulic cylinder drive is one of most advanced structure types in disc disperser. Adopting single hydraulic drive can solve 
sealing problem of main shaft on disc disperser ; Sealing points change from 4 to 2 ; Adding C-type air filter results in balancing 
lubrication cavity pressure and atmospheric pressure. It extends the design service life of V-shaped sealing ring. Add new assem
bly sealing in the front end of disc disperser with single hydraulic cylinder drive on the basis of keeping the original sealing. Both of 
sealing dually protect the sealing of main shaft.
