High U Trough Shaftless Screw Conveyor For Sludge Treatment
Introduction
Dewatered residuals from environmental processes including water
and wastewater treatment are ideal applications for KWS Shaftless
Screw Conveyors. Wet and sticky bulk materials such as dewatered
biosolids, grit and screenings are efficiently conveyed with a
shaftless spiral, eliminating the need for internal bearings or a
center pipe. Conveying efficiency is improved where elevation
changes are required because the shaftless spiral allows for higher
trough loading. The perfect solution to efficiently and reliably
convey dewatered residuals are KWS Shaftless Screw Conveyors.

Main Features
1. Shaft-less structure, less contact with the residue, low
friction, the extrusion efficiency can be improved. No clogging and
no winding.
2. Made of stainless steel with high strength, good corrosion
resistance and long service life.
3. Driving device adopts axle direct drive mode, which is stable,
reliable, and energy saving.
4. Outlet is assembled with a spring baffle to increase the
extrusion pressure and increase the dehydration rate.
5. Except for the inlet and outlet, the rest structure is closed,
and the environment is clean and sanitary.
Product Application:
1. Ceramic industry: clay, silica, sand, polishing materials, etc.
2. Food industry: soybean, peanut, starch, milk powder, salt,
sugar, etc.
3. Plastics industry: plastic powder, plastic particles, etc.
4. Wood industry:wood chips, wood sawing surface and byproducts,
etc.
5. Environmental: the filter material, fly ash, fixed residue,
waste, etc.
6. Agriculture:livestock feed, food, powder, etc.
