Bottom sludge powder material paddy scraper machine slag chain conveyor limestone powder, Working principle:When the spiral shaft rotates, due to the gravity of the material and the friction generated with the trough wall, the material can only be pushed forward along the bottom of the conveyor's trough by the blades, similar to how a non-rotating nut moves translationally along a rotating screw. The movement of the material at the intermediate bearings relies on the thrust from the material advancing from behind. Therefore, the transportation of material in the conveyor is a sliding motion. To keep the spiral shaft in a favorable tension state, the driving device and discharge outlet are generally placed at the same end of the conveyor, while the feed inlet is positioned as close as possible to the other end near the tail.The rotating spiral blades push the material for transportation, and the force preventing the material from rotating with the spiral conveyor blades is the material's own weight and the frictional resistance from the conveyor casing. The blade surface types include solid surface, belt surface, and blade surface, depending on the material being conveyed. At the end of the material movement direction, the spiral shaft of the conveyor has a thrust bearing to withstand the axial reaction force from the material. For longer conveyor lengths, intermediate hanging bearings should be added.

Application range and characteristics: (1) The spiral conveyor is widely used in chemical, building materials, grain, and other sectors, mainly for conveying powdered, granular, and small lump materials. It is not suitable for conveying perishable, sticky, or easily agglomerated materials. (2) The operating environment temperature for the spiral conveyor is -20°C to 50°C; the conveyor's inclination angle β ≤ 20°; the conveying length is generally less than 40m, with a maximum of 70m. (3) Compared to other conveying equipment, the spiral conveyor has advantages such as simple structure, small cross-sectional size, good sealing performance, the ability to load and unload at multiple points along the length, safe and convenient operation, and low manufacturing cost. Its disadvantages include severe wear of components, lower conveying capacity, high power consumption, and the tendency for materials to break during transportation.Bottom sludge powder material paddy scraper machine slag chain conveyor limestone powder.
