Brief Introduction
LS screw conveyor is the updated model of the GX type screw conveyor. The whole conveyor is reliable, durable, adaptable, easy to install. It is suitable for conveying the powder, granular, and block materials (temperature <200℃),such as coal powder, coal ash, argil, sand, cement, carbamide etc. The screw conveyor is not only used for the concrete batching plant, bituminous concrete batching, but also for the chemical, building, food, metallurgy and so on.
Working Principle
When the screw shaft of the conveyor rotates, due to the gravity of the material and the frictional force between it and the tank wall, the material can only move forward along the groove bottom of the conveyor under the push of the blade, and it seems that it cannot rotate. The nut moves in translation along the rotating screw. The main forward power of the material comes from the force that the helical blade rotates in the axial direction to move the material upward and forward along the tangential direction of the blade.
Performance and Advantages
1) The structure is relatively simple and the cost is low.
2) Reliable work, easy maintenance and management.
3) Compact size, small section size and small footprint. It is easy to enter and exit hatches and carriages during unloading and unloading operations in ports.
4) It can realize sealed transportation, which is conducive to the transportation of easy-to-fly, hot and strong-smelling materials, which can reduce environmental pollution and improve the working conditions of port workers.
5) Easy to load and unload. The horizontal screw conveyor can be loaded and unloaded at any point on its conveying line; the configuration of the vertical screw conveyor can have excellent reclaiming performance relative to the screw reclaiming device.
6) It can be conveyed in the reverse direction, or one conveyor can convey materials in two directions at the same time, that is, to the center or away from the center.
7) The unit energy consumption is large.
8) The material is easy to be crushed and worn during the conveying process, and the wear of the spiral blade and the trough is also serious.
Application Area
The screw conveyor is mainly used for conveying various powdery, granular and small block materials. , chemical fertilizers and other chemicals, as well as coal, coke, ore and other bulk cargo.
