Overview
Screw conveyor in Concrete Mixing Plant is mainly used for transporting powdery material or granular material. The material is transported by means of the continuous spinning of spiral vanes in screw conveyor.
Screw conveyors are mainly used for conveying powdery and micro granular materials such as cement, fly ash, mineral powder, dry mortar, etc.
Specifications
The screw conveyor supports customization, non-standard processing, diameter 100-600mm, length 1-70m, materials are carbon steel, stainless steel, wear-resistant steel, heat-resistant steel; the thickness of the blade is 2-6mm, and the speed is 20-150/min. Different sizes of batching plant equip different sizes of screw conveyors. Usually, its diameter is Φ219, Φ273 and Φ323. The common length is from 6m to 12m.

Advantages
1 The output of the screw conveyor can reach 500 cubic meters per hour, and the length can reach 60m, which can be customized according to customer needs.
2 It contains a sealing system to prevent dust and protect the environment.
3 It has undergone anti-seepage water treatment and can be used in the open air and rainy days.
4 It has an automatic lubrication system to extend service life.
Spiral blades are formed at one time with reasonable design and will never be blocked.
5 It uses an adjustable speed motor with sufficient power.
6 High-quality reducer, large torque, low noise.
Working
When the screw shaft rotating the gravity of the material and the friction force generated by the material and trough wall let the material move forward along the bottom of the conveyor with the thrust of blade. The conveying of material in the middle bearing relies on the forward thrust of hinder material. The screw conveyor promote the material to move forward by the fixed screw’s rotational motion and rectilinear motion.
