Shaftless Screw Conveyor Description
Shaftless screw conveyors are designed to handle almost any bulk material, from dry and free-flowing to sticky and sluggish. Shaftless screw conveyors are ideal for bulk materials with high moisture content that have a tendency to adhere to the center pipe of a conventional shafted screw conveyor.
After performance requirements and product characteristics are known, begins a systematic design process by applying proprietary calculations to determine conveyor size, rotational speed and horsepower to deliver the desired capacity. Due to the stresses associated with conveying sluggish and often abrasive bulk materials, high performance, heavy-duty materials of construction are integrated into a Shaftless Screw Conveyor system.
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°.

High 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.
