304 stainless steel U-shaped sludge screw conveyor coal sand grain conveying equipment feeder manufacturer
Screw conveyor is a kind of machinery that uses the motor to drive the screw to rotate and move materials to achieve the purpose of conveying. It can transport water products in an inclined or vertical manner. It has the characteristics of simple structure, small cross sectional area, good sealing, convenient operation, easy maintenance, and convenient sealed transportation. Generally, it is divided into axial screw conveyor and shaftless screw conveyor.
Working principle
When the screw conveyor is working, the motor drives the rotating spiral blades to move the materials and transport them. The spiral blades welded on the rotating shaft of the screw conveyor have solid surface type, belt surface type, blade surface type and other types according to the different materials transported. The force that prevents the material from rotating with the screw conveyor blades is the weight of the material itself and the friction resistance of the screw conveyor housing to the material.
Application
It is widely used in grain, chemical industry, building materials, metallurgy, mining, electric power and other departments, mainly for conveying small granular, powdery and small pieces of materials. It is not suitable for conveying materials that are easy to deteriorate, have high viscosity and caking, and have high water content.
Product features
1. Simple structure and low cost
2. Reliable work, simple maintenance and management.
3. Compact size, small section size and small floor area. It is easy to enter and exit hatches and carriages during unloading operations at ports.
4. It can realize sealed transportation, which is conducive to the transportation of materials that are easy to fly, hot and have strong smell, reduce the pollution to the environment, and improve the working conditions of port workers.
5. Easy loading and unloading. The horizontal screw conveyor can be loaded and unloaded at any point on its conveying line; The vertical screw conveyor equipped with a screw reclaiming device can have excellent reclaiming performance.
