I. Introduction of horizontal screw conveyor

Horizontal screw conveyor is a continuous conveying machine that uses rotating screw blades to move materials along a fixed casing groove, and then conveys materials horizontally, inclinedly or vertically, commonly known as “cutter”. It is mainly composed of spiral blades (spiral body), casing, driving equipment and other components. Among them, the one with a screw shaft is called a shaft screw conveyor, and the one without a screw shaft is called a shaftless screw conveyor.

Second, the use of horizontal screw conveyor

The horizontal screw conveyor is mainly used for conveying various powdery, granular and small pieces of materials, such as soybeans, corn, flour and other food products, cement, sand, clay and other building materials, salts, alkalis, fertilizers, etc. Chemicals, and bulk bulk cargoes such as coal, coke, ores. Screw conveyors are now widely used in various operations such as building materials, chemicals, electricity, food, etc. In port terminals, screw conveyors are mainly used for ship unloading, unloading operations, and the steep and vertical transportation of bulk materials in warehouses, such as screw unloading. The screw conveyor is used for the vertical lifting and horizontal transportation of the machine.

Three, the structural characteristics of the horizontal screw conveyor

The horizontal screw conveyor has a simple structure, small cross-sectional dimensions, good sealing, can be loaded and unloaded at multiple points in the center, safe and convenient to operate, and low manufacturing costs. The disadvantage is that it is not suitable to transport materials that are easy to degenerate, have high viscosity, and are easy to agglomerate; the mechanical parts are more severely worn and the maintenance cost is high; the conveying length should not be too long, the conveying volume is small, the power consumption is large, and the material is easy to be broken during the conveying process Wait.
