Product description
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, pulp`s
beating degree, paper sheet`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 pulp`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 80~130℃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.
disperser`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
disperser`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.
