Difference between Vertical Screw Conveyor and Horizontal Screw Conveyor

Vertical Screw Conveyor and Horizontal Screw Conveyor are roughly the same in structure, and they are composed of driving device (motor, reducer, coupling), screw, bearing, material trough, feed port, discharge port, etc., then Vertical Screw What is the difference between Conveyor and Horizontal Screw Conveyor?

Difference between Vertical Screw Conveyor and Horizontal Screw Conveyor

1. Different working principles

Vertical Screw Conveyor is the centrifugal force generated by the high-speed rotation of the material to drive the material to move upward. When the rotation speed is not high, the material will only rotate but not rise. The material will move upward only when the centrifugal force must be greater than the frictional force between the material and the tube wall. So the vertical screw conveyor has a critical speed.

Vertical Screw Conveyor working principles

The Horizontal Screw Conveyor relies on the rotation of the screw blade to drive the material to rotate to convey the material forward horizontally.

Horizontal Screw Conveyor principle

2. Different conveying angles

Vertical Screw Conveyor adopts vertical 90° or large angle to convey powdery, granular and other non-sticky dry materials, which can solve the problem of large angle conveying.

The Horizontal Screw Conveyor conveys materials horizontally or slightly inclined (the angle is greater than 15 degrees). If the inclination is too large, it will affect the conveying efficiency and the conveying volume.

3. The conveying height is different

The conveying height of Vertical Screw Conveyor is 2-15 meters (generally no more than 8 meters is recommended), because Vertical Screw Conveyor relies on the centrifugal force of materials to lift up, and there is a height limit. After exceeding a certain height, the conveying effect required by the customer cannot be achieved under the condition of a certain critical speed.

The Horizontal Screw Conveyor has a conveying length of 2-70 meters, relying on the rotation of the helical blades. When the length is large, you can choose large-scale equipment or purchase a high-power motor to ensure the conveying efficiency.

4. The delivery volume is different

Vertical Screw Conveyor delivery capacity: 140 cubic/hour

Horizontal Screw Conveyor delivery capacity: 458 cubic/hour

The speed of the screw conveyor has a maximum limit, and the Vertical Screw Conveyor will consume part of the power to drive the object to move centrifugally, so under the same model, the conveying capacity of the Vertical Screw Conveyor is only half of that of the Horizontal Screw Conveyor.
