The screw conveyor is a material conveying equipment widely used in various industrial fields. Its working principle is to drive the spiral rotation through the motor, thereby moving the material to achieve the purpose of conveying. The following is a detailed introduction to the screw conveyor:

Working principle

The screw conveyor transports the material through the rotating spiral blades. The material's own weight and the resistance of the screw conveyor casing to the material prevent the material from rotating together with the spiral blades.

The screw shaft has a thrust bearing at the end of the material movement direction to withstand the axial reaction force of the material to the screw. When the machine length is long, an intermediate suspension bearing should be added.

Type: In terms of transportation form, screw conveyors are divided into two types: shaft screw conveyors and shaftless screw conveyors.

In terms of appearance, screw conveyors are divided into U-shaped screw conveyors and tubular screw conveyors.

Applicable materials: The shaft screw conveyor is suitable for non-sticky dry powder materials and small particle materials, such as cement, fly ash, lime, grain, etc.

Shaftless screw conveyors are suitable for conveying sticky and easily entangled materials, such as sludge, biomass, garbage, etc.

Usage scenarios: Screw conveyors are widely used in food processing, chemical industry, environmental protection, agriculture, construction and other fields. Food processing field: used to transport various powdery, granular and small lump materials.

Chemical industry: used to transport powdery or granular chemical raw materials with certain corrosiveness.

Environmental protection field: used to transport solid waste, sludge and other materials. Its good sealing properties help prevent material leakage and dust.

Agricultural field: used to transport fertilizers, seeds and other agricultural products to improve agricultural production efficiency.

Construction field: used to transport sand, cement and other construction materials to reduce labor intensity and improve construction efficiency.

Advantages and Disadvantages: Advantages: wide application range, long conveying distance (up to more than 200m), simple structure, small footprint, and easy installation.

Disadvantages: Materials that are easy to accumulate and have strong viscosity are prone to accumulation and blockage. The noise is loud during transportation and the maintenance cost after use is high.

Market situation

There are many brands and models of screw conveyors on the market, such as LS-type screw conveyors, U-type screw conveyors, etc. These equipment are usually produced and provided by professional machinery and equipment manufacturers.

In short, as an efficient and practical material conveying equipment, screw conveyor plays an irreplaceable role in industrial production. When selecting and using, it is necessary to consider comprehensively based on material characteristics, site conditions and equipment requirements.
