Classification and working principle of screw conveyor
The classification of screw conveyor
1) Tubular screw conveyor,
2) U-shaped groove screw conveyor,
3) Horizontal screw conveyor,
4) Vertical screw conveyor,
5) inclined screw conveyor;
The working principle
The rotating shaft with the spiral piece rotates in a closed trough, so that the material loaded into the trough does not rotate with the spiral due to its own gravity and its friction against the trough. Only move forward along the trough.
The main features
1) The structure is simple, compact, small in floor space, low in production cost, low in maintenance and low in cost;
2) Because it is made of seamless pipe, the sealing effect is good, so it is suitable for easy flying, hot materials, toxic and odorous materials;
3) It is possible to feed more points and cut more materials;
4) It has stirring, mixing and cooling operations;
5) Main disadvantages: relatively high power consumption, unsuitable for materials with high hardness, products that are not suitable for high water content with high viscosity, products that need to be cleaned frequently, and very sensitive to overload.
