1. With good environmental protection performance, the fully closed and easy to clean spiral surface can ensure that the delivered materials are not polluted and will not leak.

2. The large conveying capacity is 1.5 times of the axial screw conveyor with the same diameter.

3. Large turning distance, low energy consumption, no blockage of the discharge port. Because the screw has no shaft, the material is not easy to be blocked, and the discharge port is not blocked, so it can operate at a lower speed, drive stably, and reduce energy consumption. The torque can be 4000N/m.

4. The conveying distance is long, and the conveying length of a single machine can reach 60~70m. According to the user's needs, multi-stage tandem installation can be used to transport materials over a long distance.

5. Compact structure, space saving, beautiful appearance, simple operation, economical and durable.

6. The anti entanglement property is stronger than that of conveying belt shaped, viscous materials and easily entangled materials. For example, it can prevent accidents caused by blockage when it is used to transport medium and fine grids in sewage treatment plants, such as trash remover grid slag and filter press mud cake with a net distance of 50mm between the grid bars, or when the garbage is transported in garbage treatment sites.

7. The highly mobile shaftless screw conveyor can work flexibly and one machine can be used for many purposes. It can discharge both from the bottom and from the end. With lining plate, the machine can work under high temperature. Compact structure, space saving, beautiful appearance, simple operation, economical and durable.
