Screw Conveyor

Brief Description

Screw conveyor is commonly known as auger. It is a kind of conveyor equipment widely used in minerals, feed, grain and oil, construction industry. The screw conveyor uses the rotating spiral to transport the conveyed materials along the fixed casing. In operation, the screw conveyor is divided into a shaft screw conveyor and a shaftless screw conveyor in the form of conveying, and is divided into a U-shaped screw conveyor and a tubular screw conveyor in the outer shape. Axial screw conveyors are suitable for non-stick dry powder materials and small granular materials (eg cement, fly ash, lime, grain, etc.); and shaftless screw conveyors are suitable for conveyors from viscous and entangled materials ( For example: sludge, biomass, garbage, etc.)

Feature & Benefits

1. The structure is relatively simple and the cost is low.

2. Reliable work and easy maintenance and management.

3, compact size, small cross-section size, small footprint. It is easy to enter and exit hatches and compartments during unloading and unloading operations at ports.

4, can achieve sealed transportation, is conducive to transport easy to fly, hot and irritating materials, can reduce environmental pollution, improve the working conditions of port workers.

5, loading and unloading is convenient. The horizontal screw conveyor can be loaded and unloaded at any point on its transport line; the ability to automatically reclaim the screw shaft in direct contact with the material stack can be used as a reclaimer for other types of port unloading machinery.

It can be transported in reverse direction. It can also make a transporter transport materials in two directions at the same time, that is, to the center or away from the center.

Screw conveyors are widely used in various sectors of the national economy such as grain industry, building materials industry, chemical industry, machinery manufacturing, and transportation.

The screw conveyor is mainly used to transport various powdery, granular and small block materials. The bulk materials transported are grain, beans, flour and other food products, cement, clay, sand and other building materials, salt and alkali. Chemicals such as fertilizers, as well as bulk cargo such as coal, coke, ore. Spiral conveyors are not suitable for transporting materials that are prone to deterioration, viscous, bulky and agglomerated. In addition to transporting bulk materials, screw conveyors can also be used to transport a variety of individual items.
