Double-row chain scraper slag remover, chemical plant scraper, metallurgical automatic conveyor. Screw conveyors are suitable for non-viscous dry powder materials and small granular materials.(For example: cement, fly ash, lime, grain, etc.), whileshaftless screw conveyorsare suitable for conveying viscous and easily entangledmaterials. Screw conveyors are divided into two types based on their conveying form: shaft screw conveyors and shaftless screw conveyors. In terms of appearance, they are classified intoU-type screw conveyors and tubular screwconveyors.Shafted materials (for example: sludge, biomass, garbage, etc.). The working principle of a screw conveyor is that the rotating spiral blades push thematerialforward for conveying. The force that prevents the material from rotating with the screw conveyor blades is the weight of the material itself and the frictional resistance of the conveyor casing against the material. The spiral blades welded onto the rotating shaft of the screw conveyor come in different surface types depending on the material being conveyed, including solid surface type, belt surface type, and blade surface type. At the end of the screw shaft in the direction of material movement, there is a thrust bearing to withstand the axial reaction force from the material. For longer conveyor lengths, intermediate hanging bearings should be added.

Screw conveyors generally consist of three main parts: the conveyor body, the inlet and outlet ports, and the driving device. The spiral blades of screw conveyors come in three forms: solid spiral surface, belt spiral surface, and blade spiral surface. Among these, the blade spiral surface is relatively less used and is mainly employed for conveying highly viscous and compressible materials. This type of spiral surface not only completes the conveying process but also performs functions such as mixing and blending the materials. Compared to other conveying equipment, screw conveyors offer advantages such as small cross-sectional dimensions, good sealing performance, stable and reliable operation, the ability to load and unload materials at multiple points along the length, operational safety, and ease of maintenance.Double-row chain scraper slag remover, chemical plant scraper, metallurgical automatic conveyor.
