Shaftless screw conveyor is the spiral blade without shaft, which is relative to shafted screw conveyor,its main features are simple structure, no central shaft in the trough, smooth material conveying, easy maintenance; except for the open inlet and outlet, the rest of the parts can be closed with a cover, the material will not spill, reducing air pollution. The shaftless screw conveyor is suitable for continuous and uniform conveying of loose, viscous and easy to wind materials.
The main Features of shaftless screw conveyor are as follows:
1. Shaftless screw conveyor can convey materials that cannot be or are not easily conveyed by traditional shafted screw conveyors and belt conveyors, such as granular and powdery materials, wet and pasty materials, semi-fluid and viscous materials, materials that are easily tangled and clogged, and materials with special hygiene requirements.
2. Good environmental performance. The fully enclosed and easy-to-clean spiral surface ensures that the conveyed material is not contaminated and does not leak, and the weight and cost are reduced a lot compared to the shafted screw conveyor.
3. Large handling capacity, capacity is 1.5 times of the same diameter shaft screw conveyor.
4. Large rotation distance, low energy consumption, discharge port is not blocked.
5. Long conveying distance, single machine conveying length up to 60~70m.
6. Compact structure, space saving, beautiful appearance, easy operation, economic and durable.
The Shaftless screw conveyor consists of drive unit, head thrust bearing, casing, shaftless screw blade, trough liner, inlet and outlet, etc.Shaftless screw conveyor is a transportation machine,compared with the traditional shafted screw conveyor, the shaftless screw conveyor is designed without a central shaft and has no central shaft interference, so it has special advantages for conveying strip and easy winding materials. The use of a flexible overall steel screw conveyor to push the material, and therefore has more outstanding advantages: strong resistance to winding.
