The composition of the buried scraper chain conveyor can be reversed and customized as needed. Daily Maintenance Management:During the use of the screw conveyor, it is essential to pay attention to daily maintenance to ensure optimal cooperation with the sand dryer, guaranteeing production capacity and efficiency, as well as 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 and perform welding repairs if the wear is severe.(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 materials at high temperatures, ensure that the casing expands and contracts freely without any obstructions; address any issues promptly.(5)If the conveyor emits harsh noise during operation, open the cover for inspection and troubleshoot the issue.

When material is fed into the fixed chute, due to the gravity of the material and the friction between the material and the chute, the material accumulated at the bottom of the chute does not rotate with the screw. Instead, it is pushed forward by the rotating spiral blades, similar to a non-rotating nut moving along a rotating screw, achieving the purpose of conveying material. This machine facilitates multi-point loading and unloading and can simultaneously perform mixing, stirring, or cooling functions during the conveying process. It is sensitive to overload and prone to clogging; it may cause crushing and wear to the material. The horizontal screw conveyor has a simple structure, making it easy to install, maintain, and troubleshoot. It is suitable for horizontal or slightly inclined (below 20o) continuous and uniform conveying of loose materials, with an operating environment temperature of -20 to +40°C and a material temperature range of -20 to +80°C. Its rotational speed is relatively lower compared to vertical conveyors, primarily used for horizontal or small-angle material conveying, with a conveying distance generally not exceeding 70 meters.
