Difference between screw conveyor and belt conveyor

Screw conveyors and belt conveyors are the same as the conveyor equipment, and they have great differences in transportation,so what are the differences? Today, I’m here to introduce you from the following aspects.

The way to convey material is different

The screw conveyor transports the belt conveyor in a linear or linear manner.

The screw conveyor can be transported in any direction. The belt conveyor can only be transported in a straight line or linearly in a nearly horizontal direction.

The structure of the device is different

The structure of the screw conveyor is mainly composed of spiral tube, spiral blade, screw shaft, motor, drive, sealing device and other components.

The belt conveyor mainly consists of a frame, a conveyor belt, a belt roller, a tensioning device and a transmission device.

The working principle is different

The working principle of the screw conveyor is that the rotating spiral blade conveys the material and carries the screw conveyor, so that the force of the material not rotating together with the screw conveyor blade is the weight of the material itself and the friction resistance of the screw conveyor casing to the material.

The working principle of the belt conveyor is a conveyor belt supported by the upper and lower rollers as a carrier member and a traction member, and a conveying mechanism that forms a closed loop around the head and tail rollers, which is transmitted by friction between the driving roller and the conveyor belt. Power, material delivery.

The materials delivered are different

Screw conveyor: It is mainly used for horizontal transportation and vertical lifting of loose materials such as powder, granules and small blocks. The machine is not suitable for conveying deterioration, large viscosity, easy to agglomerate or high temperature, and is afraid of pressure. Corrosive special substances.

Belt Conveyor: Delivers items below 100KG or powdery or granular items. Belt conveyors are widely used in metallurgy, coal, transportation, hydropower, and chemical industries.
