Quartz sand tubular screw conveyor single tube feeding ash conveying machine, Daily maintenance management:During the use of the screw conveyor, daily maintenance must be emphasized to maximize coordination with thesand dryer, ensuring production capacity and efficiency, and extending the equipment's service life.(1)Lubricating oil should be regularly applied to transmission parts such as bearings, gears, and chains.(2)After the conveyor is shut down, inspect the wear of the spiral blades; if severely worn, perform repair welding.(3)Do not overload the conveying capacity, as it may prevent material discharge, causing bending of the screw shaft and damage to the casing.(4)When conveying high-temperature media, ensure the casing expands and contracts freely without obstruction; address any issues promptly.(5)If the conveyor emits harsh noise during operation, open the cover for inspection and troubleshoot the issue.

Screw conveyors are suitable for non-viscous dry powder materials and small granular materials (e.g., cement, fly ash, lime, grains, etc.), while shaftless screw conveyors are suitable for conveying viscous and easily entangled materials. Screw conveyors are categorized into shafted screw conveyors and shaftless screw conveyors based on their conveying form, and into U-type screw conveyors and tubular screw conveyors based on their shape. Shafted materials (e.g., sludge, biomass, garbage, etc.). The working principle of a screw conveyor is that the rotating spiral blades push the material forward for conveying. The force preventing the material from rotating with the blades is the material's own weight and the frictional resistance between the material and the conveyor casing. The spiral blades welded onto the rotating shaft of the screw conveyor come in various surface types depending on the material being conveyed, including solid surface type, belt surface type, and blade surface type. At the end of the material movement direction, the screw shaft of the conveyor is equipped with a thrust bearing to withstand the axial reaction force from the material. For longer conveyor lengths, intermediate hanging bearings should be added.Quartz sand tubular screw conveyor single tube feeding ash conveying machine.
