Shaftless Screw Conveyor Description
Shaftless screw conveyor according to the building material, chemical industry, environmental protection,
electric power, medicine, metallurgy, food and other industries in the LS type, GX type screw conveyor conveying grinding cut big, viscosity is bigger, is easy to agglomerate, wrapping easily material formed when material blockage, suspension bearing damage to the actual situation of screw machine doesn't work and independent research and development of a new type of screw conveyor. This product is suitable for continuous and uniform conveying of loose, sticky and easily wound materials, the temperature of conveying materials is up to 100℃, the maximum inclination Angle is less than 30°.
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.
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 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
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
