Advantages and Disadvantages of Vertical Screw Conveyor

The vertical screw conveyor is suitable for conveying powdery, granular and non-sticky materials vertically or at a large inclination angle. This article will analyze the advantages and disadvantages of the vertical Screw conveyor in detail.

Advantages of vertical screw conveyor

1. Good sealing performance, reduce environmental pollution

The outside of the spiral is equipped with a casing, which has good sealing performance, and will not cause dust or material splash when conveying materials, reducing environmental pollution.

2. Vertical conveying

Its running direction is vertical upwards to meet the needs of customers for conveying up and down materials, and the length is appropriately increased according to customer needs; the vertical screw conveyor has a small area, convenient loading and unloading, moving, simple operation, convenient repair and maintenance.

3. Large delivery volume

The conveying capacity is large, the conveying efficiency is high, and the output can reach 6-300 tons/hour; and the vertical screw conveyor relies on the friction between the material and the inner wall of the casing and the upward centrifugal force to promote the material to move upward with the rotation of the spiral blade Conveying, compared with traditional belt conveyors, it saves 50% of electricity and consumes less energy.

Disadvantages of vertical screw conveyor

1. Short conveying distance

The conveying distance of the vertical screw conveyor is limited, the longest is 40m. The conveying material effect is the best in this range. If this threshold is exceeded, the conveying efficiency and output will decrease.

2. The conveying materials are restricted and easily broken

Compared with ordinary screw conveyors, they are generally used to convey flour, powdery materials, and small granular materials. When the material moves upward, its own gravity and the centrifugal force of the equipment will collide. If the gravity of the material is too large, it will affect Conveying efficiency; and the spiral blade will collide with the material, causing the material to be broken.

3. The equipment is easy to wear

The vertical screw conveyor uses the friction force between the material and the inner wall of the casing to pull up the material conveying. The screw blades, the pipe wall and the material are in full contact, and the wear is fast, which will increase the maintenance cost.

Each machine has its advantages and disadvantages. We need to select the appropriate model based on its advantages to maximize the performance of the machine.
