Advantages And Limitations of Shaftless Screw Conveyor

Shaftless screw conveyors can easily discharge materials such as sludge, pulp, garbage, etc. from centrifuges, filter presses or mixers, our shaftless design provides a clog-free conveying Material becomes easy to convey, this article will explain in detail the advantages and disadvantages of shaftless screw conveyors.

Advantages of Shaftless Screw Conveyors

1. No sticking or blocking

Ordinary shafted screw conveyors will block when conveying belt-shaped, viscous materials, and easy to entangle, and even cause the screw shaft to be stuck. Shaftless screw conveyors can avoid material clogging because there is no intermediate bearing.

2. The conveying distance can reach 32 meters

The length can reach 32 meters, and it is also installed in multi-stage series. 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

Wear-resistant plastic plate or rubber plate or cast stone plate, etc., the service life is guaranteed to be more than 2 years.

Disadvantages of Shaftless Screw Conveyors

1. The blades are easy to wear

Due to the lack of an intermediate shaft, all the force is on the blades, so the blades are required to have sufficient strength and rigidity. In this case, we can make the thickness of the blades not less than 20mm, and the height of the spiral blades not less than 80mm, which can be greatly improved. Extend the life cycle.

2. Low inclination angle

Shaftless screw conveyors generally transport horizontally, and can also be inclined at 25°. If the transport angle is too large, the effect will be affected.

The above is an introduction to the advantages and disadvantages of shaftless screw conveyors. Shaftless screw conveyors have been successfully used in the entire chemical, food, mineral processing and wastewater treatment industries for conveying various viscous, pasty, strips, etc. clogged material.
