The shaftless screw conveyor is a material conveying equipment designed without a central shaft, which pushes materials through an integral steel spiral body and has the characteristics of strong anti winding and good environmental performance. The following are its main features and applications:
1、 Core Features
Resistance to entanglement
The design without a central axis avoids the entanglement problem of strip-shaped and viscous materials such as slag, sludge, and garbage, making it particularly suitable for the sewage and garbage treatment industries.
Efficient transportation
The conveying capacity can reach 1.5 times that of equipment with shafts of the same specifications, and the maximum conveying length of a single machine is 60 meters. It supports multi-stage series ultra long distance conveying.
Environmentally friendly sealing
The fully enclosed structure prevents material leakage, and the spiral surface is easy to clean, meeting hygiene requirements.
Low energy consumption and high torque
The torque can reach 4000N/m, running smoothly at low speeds with low energy consumption.
2、 Structural composition
Drive device: Cycloid pinwheel reducers or hard toothed gear reducers are commonly used, usually installed at the discharge end.
Spiral body: made of stainless steel or carbon steel, with no shaft design.
Chassis: U-shaped or O-shaped, available in stainless steel, carbon steel, or fiberglass materials.
Lining plate: Made of wear-resistant plastic, rubber, or cast stone to reduce friction.
3、 Application scenarios
Wastewater treatment: conveying grid slag, filter press mud cake.
Chemical/papermaking: Processing viscous and easily tangled materials.
Waste disposal: transportation of household waste, etc.
