Customized SS304 Shaftless Screw Conveyor Manufacturer
Shaftless Screw Conveyor Description
The conveyors are of robust and simple construction which means limited maintenance and low running costs. The conveyors are constructed in stainless steel and after machining completely pickled. Thus, an optimal durability of material is ensured.
Transportation takes place by a shaftless screw conveyors which is embedded in a wearing plate of plastic material. The screw is made of high-strength carbon steel with a stainless steel screw available as an option.Can also be used to transport other materials such as wood chips to the stoker, or applesauce.

This product is mainly composed of drive device, head assembly, housing, no shaft helix, slot liner, feed port, discharge port, cover (when needed), base, etc.
- Driving device: cycloidal needle wheel reducer or shaft mounted gear reducer with hard tooth surface shall be adopted. The driving device shall be set at the outlet of the material as far as possible in the design to make the helix in the state of tension during operation.
- The head is equipped with thrust bearing, which can bear the axial force generated during material transportation.
- Housing: the housing is u-shaped or o-shaped, with a rain-proof cover on the top. The material is stainless steel or carbon steel or fiberglass.
- No shaft helix: the material is stainless steel or carbon steel.
- Slot lining board: wear-resistant plastic board or rubber board or cast slate, etc.
- Inlet and outlet: there are two types of inlet and outlet: square and round. The general inlet and outlet form is determined by the user.
Shaftless Screw Conveyor Feature
- Shaft-less structure, less contact with the residue, low friction, the extrusion efficiency can be improved. No clogging and no winding.
- Made of stainless steel with high strength, good corrosion resistance and long service life.
- Driving device adopts axle direct drive mode, which is stable, reliable, and energy saving.
- Outlet is assembled with a spring baffle to increase the extrusion pressure and increase the dehydration rate.
- Except for the inlet and outlet, the rest structure is closed, and the environment is clean and sanitary.
Shaftless Screw Conveyor Applications
- Ceramic industry: clay, silica, sand, polishing materials, etc.
- Food industry: soybean, peanut, starch, milk powder, salt, sugar, etc.
- Plastics industry: plastic powder, plastic particles, etc.
- Wood industry:wood chips, wood sawing surface and byproducts, etc.
- Environmental: the filter material, fly ash, fixed residue, waste, etc.
- Agriculture:livestock feed, food, powder, etc.
