Advantages and Limitations of Vertical Screw Conveyors

The vertical screw conveyor is used to transport materials along the vertical path, and convey powder or granular materials from low to high.

Advantages of Vertical Screw Conveyors

1. Suitable for vertical lifting of various bulk materials

Ideal for handling dry to semi-fluid materials from free-flowing to slightly sluggish.

2. The lifting height can reach 8 meters

For lifting/loading powder to the height required for filling hoppers and/or silos, up to 8 meters, when increased lift height is required, intermediate hangers or stabilizer bearings are often required to eliminate excessive helical deflection.

3. Small footprint

Compared with bucket elevator or pneumatic conveying system, vertical screw conveyor has the most compact overall size,

4. Good sealing

The fully enclosed design meets dust-proof requirements and improves the conveying environment.

Limitations of Vertical Screw Conveyors

1. The conveying material is limited and easily broken

Compared with ordinary screw conveyors, it is generally used to transport similar flour, powdery materials and small granular materials, because when the materials move upward, their own gravity and the centrifugal force of the equipment will collide. Conveying efficiency; the spiral blade will collide with the material, causing the material to be broken.

2. The equipment is easy to wear

The vertical screw conveyor relies on a high screw speed to transport materials upwards. The screw blades and the pipe wall are in full contact with the materials, and the wear and tear is fast, which will increase the maintenance cost.

The above is an introduction to the advantages and limitations of vertical screw conveyors. Vertical screw conveyors are suitable for taking out bulk materials from silos, hoppers, conveying or feeding devices. Silo or A silo or another conveyor or conveyor system.
