Urea phosphate powder type buried scraper conveyor stainless steel feeding scraper conveyor various specifications, Daily maintenance management: During the use of the screw conveyor, it is essential to pay attention to daily maintenance and care, so as to cooperate well with the sand dryer, ensuring production capacity and efficiency, and also extending the service life of the equipment. (1) Lubricating oil should be regularly applied to transmission parts such as bearings, gears, and chains. (2) After the conveyor is stopped, check the wear of the spiral blades, and perform welding repairs if the wear is severe. (3) The conveying capacity must not be overloaded, otherwise the material cannot be discharged, causing the spiral shaft to bend and the casing to swell and break. (4) When the temperature of the conveyed medium is high, pay attention to whether the expansion and contraction changes of the casing are free and without any jamming; if there is, resolve it promptly. (5) When the noise emitted during the operation of the conveyor is harsh, open the cover for inspection and troubleshoot.

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 move forward along the bottom of the conveyor's trough under the push of the blades, similar to how a non-rotating nut moves translationally along a rotating screw. The movement of the material at the intermediate bearing relies on the thrust of 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 more favorable tension state, the driving device and discharge port are generally placed at the same end of the conveyor, while the feed port is placed as close as possible to the other end. The rotating spiral blades push the material for conveyance; 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 blade profile varies according to the material being conveyed, including solid face type, belt type, blade type, etc. The spiral shaft of the screw conveyor has a thrust bearing at the end of the material movement direction to withstand the axial reaction force from the material; when the machine length is long, intermediate hanging bearings should be added.
