Compared with traditional screw conveyor having shaft, the shaftless screw conveyor can make use of its whole steel spiral that having certain flexibility to transport materials,Because it is designed without shaft and suspending the bearing. thus it has the following advantages:

1,Screw has super wear resistance and durability and long service life.

2,Good anti-winding property:Without center shaft interference, it has special advantages for conveying ribbon pattern material and easy winding material , because there is no shaft ,so it can certainly avoid blocking by this design and reduce accident.

3,Good environmental performance:Adopting the totally closed delivery and easy cleaning surface of the spiral, it can ensure the environmental health and the material from pollution and leakage.

4,Big torque, low energy consumption:It can run in low speed and stably transport because of the screw without shaft, and material is not easy to be blocked,so it can reduce energy consumption to a great extent.

5,Large throughput:Its throughput is 1.5 times as large as than the same diameter traditional conveyor with shaft,The largest throughput can reach up to 40 m³ / h.

6,Long delivery distance:The delivery distance can be up to 25 m.it also can transport longer distance by multistage tandem installation, according to demands of users.

7,Other characters:Compact structure, convenient operation, economy and durability, fewer maintenance and lower maintenance cost.
