Small lump material tubular screw conveyor spiral auger blades. 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 the 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 screw conveyor transportation. The force that prevents the material from rotating with the screw conveyor blades is the material's own weight and the frictional resistance of the screw 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. When the machine length is long, intermediate hanging bearings should be added.The spiral tube conveyor has continuous spiral blades welded inside a cylindrical casing, and the casing rotates together with the spiral blades. The added material, due to centrifugal force and friction, rotates with the casing and is lifted. Then, under the gravity of the material, it slides down along the spiral surface, causing the material to rotate with the spiral tube, thereby achieving forward movement of the material. This is similar to a non-rotating screw moving translationally along a rotating nut, achieving the purpose of conveying materials. This machine has low energy consumption and low maintenance costs; when feeding from the end, it can adapt to uneven feeding requirements and can simultaneously complete various process requirements such as conveying, mixing, and blending. Even if too much material enters, it will not cause blockage; it facilitates multi-point loading and unloading and can convey materials at higher temperatures. It is suitable for horizontally conveying high-temperature materials; it has good adaptability for materials with high temperatures, uneven feeding, requirements for anti-breakage and anti-pollution, and processes requiring multi-point loading and unloading. Practice has proven that it performs well in conveying materials such as cement clinker, dry limestone, phosphate rock, ilmenite powder, coal, and slag. The particle size of materials added from the end feed inlet must not exceed1/4of the screw diameter; for materials added from the middle feed inlet, the particle size must not exceed30millimeters. To ensure that the cylinder does not deform, the feeding temperature must be controlled below300°C. This machine causes severe wear on the blades and trough when conveying highly abrasive materials. The screw conveyor designed this time is mainly used for conveying silica fume, which is highly abrasive, so it is not suitable to use a spiral tube conveyor.Small lump material tubular screw conveyor spiral auger blades.
