Screw conveyor is a very important transportation equipment, which has obvious advantages compared with the traditional axis spiral, but having difficulty in the commutation winding, bonding materials for large transport, the shaftless screw conveyor perfectly solves problems, and ensuring the delivery of efficiency. The shaftless screw machine made by Henan Zhengzhou mining machinery Co., Ltd has obvious advantages of low cost, reliable operation without central axis interference. And it has special advantages for conveyor-like, easy to wound materials.

The shaftless screw conveyor can transport material that traditions shaft screw and belt conveyors could not or has difficult to transport, such as granular and powdered materials, wet and pasty materials, semi-fluid and sticky materials, materials that are easy to wound and plug, materials having special hygiene requirements. The shaftless screw conveyor’s performance characteristics are: compared with conventional shaft, the use of non-central axis design, using a certain flexibility of the overall steel auger material that has outstanding advantages over good environmental performance. Compared with the shaft screw conveyor, it will reduce a lot of weight and cost.
One. Good environmental performance. Closed spiral and the surface is easy to clean, thus ensuring that the material is not contaminated and the conveying material could not leak off.

Two. Large throughput, throughput is the same as 1.5 times the diameter of the shaft screw conveyor.

Three. Torque, low energy consumption, the discharge opening is not blocked.

Four. Transmission distance is long, single conveyor lengths are up to 60 ~ 70m.

Five. Compact, space-saving, beautiful appearance, easy to operate, economical and durable.
