Shaftless screw conveyor is a fairly recent development in screw conveyor design and is growing in popularity because it is the perfect solution for many bulk solids handling applications. The shaftless screw conveyor is the solution for conveying many difficult bulk solids. In fact, the shaftless conveyor was so successful in the Environmental industry, that its use has been promoted in many other industries such as chemical, food, and minerals processing.

Shaftless screw conveyor application:

It is widely used in building material, metallurgy, chemical industry, electric power, coal, machinery, light industry, food and food industry, suitable for conveying powder, granule, small block material, such as cement, coal, food, chemical fertilizer, ash, sand, coke, etc.

A shaftless conveyor is designed to be supported by a liner that conforms to the radius of the trough. The weight of the shaftless spiral is distributed over the full length of the spiral on the liner. The drive is connected to one end of the spiral by means of a flanged and bolted drive shaft and spiral end plate, while the tail end of the spiral is not connected and is allowed to rotate freely. If your process consists of bulk solids with high moisture content, then the shaftless screw conveyor is a perfect solution.



1.Strong anti-winding, no central axis interference. It has obvious advantages for conveying the sticky material, easy winding material.

2.Good environmental performance. It adopts fully enclosed spiral surface, which can ensure that environmental hygiene and transportation of materials from pollution, no leakage.

3.Large torque, low energy consumption. As the spiral without shaft, the material is not easy to plug, the discharge port is not blocked, which can be lower speed operation, smooth transmission, reduce energy consumption. The torque can be 4000N / m.

4.Large conveying capacity. The capacity is 1.5 times as the traditional shaft screw conveyor with the same diameter. Long conveying distance and ultra-long distance transport materials. The conveying length can reach 30 meters, which also can be adjusted according to user needs and installed by multi-level series.
