Galvanized Round Tube Type Grain and Feed Elevator Large Round Tube Type Bulk Loading, 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. The situation is similar to a non-rotating nut moving translationally along a rotating screw. The movement of the material at the intermediate bearing relies on the thrust from the material advancing from behind. Therefore, the transportation of material in the conveyor is entirely 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 placed as close as possible to the other end near the tail.The rotating spiral blades push the material for transportation. The force that prevents the material from rotating with the spiral conveyor blades is the material's own weight and the frictional resistance of the conveyor casing against the material. The blade surface types include solid surface, belt surface, and blade surface, depending on the material being conveyed. At the terminal end of the material movement direction, the spiral 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.

      Technical Features:Simple structure, small cross-sectional size, good sealing, reliable operation, low manufacturing cost, convenient for intermediate loading and unloading, reversible conveying direction, and capable of conveying in two opposite directions simultaneously. During transportation, operations such as stirring, mixing, heating, and cooling can also be performed on the material. Material flow can be regulated through loading and unloading gates. However, it is not suitable for conveying perishable, highly viscous, easily agglomerated, or large-sized materials. During transportation, materials are prone to breakage, and the spiral and trough are susceptible to wear. The unit power consumption is relatively high. During use, it is essential to maintain the sealing of the trough and an appropriate gap between the spiral and the trough.Galvanized Round Tube Type Grain and Feed Elevator Large Round Tube Type Bulk Loading.
