Spiral conveyor is widely used in various industries, such as building materials, chemical industry, power, metallurgy, coal mine charcoal, grain and other industries. It is suitable for horizontal or inclined transportation of powdery, granular and small block materials, such as coal mine, ash, slag, cement, grain, etc., with material temperature less than 200 ℃. The screw conveyor is not suitable for conveying materials that are prone to deterioration, high viscosity, and easy to clump. In concrete mixing plants, the role of screw conveyors is greatly reflected Widely used in various industries, such as building materials, chemical industry, power, metallurgy, coal mine charcoal, grain and other industries, suitable for horizontal or inclined conveying of powdery, granular and small block materials, such as coal mines, ash, slag, cement, grain, etc., with material temperature less than 200 ℃. Spiral machines are not suitable for conveying materials that are prone to deterioration, high viscosity, and clumping. In concrete mixing plants, the role of screw conveyors is greatly reflected.

The structural characteristics of the screw conveyor:

1. The connection between the spiral shaft and the suspension bearing, as well as the head and tail shafts, adopts an embedded tongue type, which does not require axial movement for installation and disassembly, making maintenance convenient. The core shaft is long, there are few hanging parts, and there are few fault points

2. Adopting a variable diameter structure, increasing the volume of the suspension bearing, avoiding contact between the suspension bearing and the material, the service life of the suspension bearing can reach more than two years.

3. Each transmission part adopts a floating connection method, and the suspension bearing is a universal joint structure, which forms a whole rotating floating body with the spiral body, suspension bearing, and tail assembly. It can freely rotate and avoid obstruction within the range according to the conveying resistance, without jamming or blocking materials.

4. The head and tail bearing seats are both located outside the shell, and all bearings adopt multi-layer sealing and cooperative sealing technology, resulting in a long service life of the bearings.
