Shaftless Screw Conveyor Description
Shaftless screw conveyor is also known as anti-winding conveyor, garbage disposal conveyor, kitchen waste screw conveyor.
Shaftless screw conveyor drive device for kitchen waste: cycloidal pinwheel reducer or shaft-mounted hard-tooth surface gear reducer is used. In the design, the drive device should be located at the discharge port end as much as possible, so that the screw body is running always in tension. WLS shaftless screw conveyor casing: the casing is U-shaped, with a cover on the upper part (if necessary), and the material is stainless steel or carbon steel or glass fiber reinforced plastic. The inlet and outlet of the shaftless screw conveyor for kitchen waste: there are two kinds of square and round.
Shaftless Screw Conveyor Structure
Shaftless screw conveyor is mainly composed of shaftless screw, U-shaped spiral groove, cover plate, lining plate, inlet and outlet, discharge outlet and driving device.
Shaftless Screw Conveyor Type
Single shaftless screw conveyor screw shaft, without mixing and stirring functions.
Twin Shaftless Screw Conveyor It adopts double screw blades with mixing and stirring functions. The two screw blades rotate in opposite directions to avoid material blocking. The conveying capacity is 1.5-2 times that of a single shaft.
Inclined Shaftless Screw Conveyor mainly used for conveying materials at a small angle of 25°.

Shaftless Screw Conveyor Benefits
- Easy to access and clean
- Low maintenance
- Modular components enable easy adaptation to various problems (results in an extremely versatile conveyor for a variety of DIFFICULT materials and a large number of applications)
- High degree of self-cleaning
Shaftless screw conveyors VS Shafted Screw Conveyors
Conveying materials
Shaftless is suitable for conveying sludge, household garbage, grid slag and other viscous, entangled materials and massive materials. It is precisely because the design of the shaftless screw conveyor without a central axis has great advantages for these materials.
The shaft screw conveyor is suitable for conveying materials: powder, small particle materials, etc. If you convey viscous
materials such as sludge, it will stick to the inner tube shaft and blades, and the conveying block materials are easy to jam.
Conveying form
Shaftless screw conveyor is suitable for: horizontal conveying, and the large inclination angle should not exceed 20°, according to the actual usage.
The shaft screw conveyor is suitable for: horizontal conveying, inclined conveying, and vertical conveying.
Conveying capacity
Due to the use of shaftless, the single-machine conveying length of the shaftless screw conveyor can reach 60 meters, and the conveying capacity is 1.5 times that of the traditional shafted screw conveyor with the same diameter
Shaftless Screw Conveyors Application
Shaftless helical (screw) conveyors are designed for handling difficult and heterogeneous materials such as municipal solid waste, screening and floating matter Substances, dehydration, thickening, conditioning sludge, packaged foods, creams or Pastes, and waste from meat, fish, fruit and vegetable processing.
Main Application areas are: wastewater treatment, sugar mill waste, fish industry, solid waste treatment, fruit and vegetable processing, beverage industry, pulp and paper, chemicals, food industry, meat processing plants, slaughterhouses, restaurants, canteens, general catering.
