The shaftless screw conveyor provides a non-clogging conveying surface, making it easy to convey materials that are difficult to convey, and can convey wet/paste materials, semi-fluid/viscous materials and other materials that are easy to entangle and easily clogged. This article will explain in detail for you Advantages and disadvantages of shaftless screw conveyor.

Advantages of shaftless screw conveyor

1. No sticking or blocking

Conveying materials that cannot or are not easy to be conveyed by shafted screw conveyors, such as granular materials, paste materials, semi-fluid and viscous materials, easily entangled materials, viscous bulk solids are easy to adhere to the central pipe of shafted screw conveyors, The shaftless screw conveyor completely eliminates this problem, because there is no central shaft, which can eliminate the accumulation of viscous materials.

2. The conveying distance can reach 32 meters

The length can reach 32 meters, and it also adopts multi-stage serial installation method, and the conveying capacity is 1.5 times that of the traditional shaft screw conveyor with the same diameter.

3. The conveyor is completely sealed, no smell or overflow

The machine cover is detachable, and the cover can be covered during transportation. The conveyed materials have no peculiar smell and overflow problems, which eliminates environmental and product pollution, greatly reduces daily maintenance and cleaning work, and can be opened at any time for cleaning.

4. Low maintenance cost

A wear-resistant plastic plate or rubber plate or cast stone plate is installed in the conveying trough to avoid damage to the machine trough caused by friction.

Disadvantages of shaftless screw conveyor

1. The blades are easy to wear

Due to the lack of an intermediate shaft, all the stress is on the blades, so the blades are relatively easy to damage, and the residue needs to be cleaned regularly.

2. Small inclination angle

The shaftless screw conveyor is generally conveyed horizontally, and can also be conveyed at an inclination of 25°. If the conveying angle is too large, the effect will be affected.

The above is an introduction to the advantages and disadvantages of the shaftless screw conveyor. The shaftless screw conveyor has been successfully used in the entire chemical, food, mineral processing and wastewater treatment industries to transport various viscous, pasty, strip-like materials that are easy to clog.
