A belt conveyor consists of a drive mechanism, tensioning device, traction chain, chains, and other related components. A belt conveyor transports materials in a horizontal or inclined direction using a series of belts fixed to a traction chain. Steel plates are hinged together to form an annular belt, which serves as the traction and load-bearing element of the conveyor. Lateral shims are placed on the bearing surface within the housing to drive the belt to transport the coal scraper via the shims. Belt conveyors are widely used in metallurgy, coal, chemicals, food, machinery manufacturing, and other industrial sectors of the national economy. Belt conveyors are characterized by long transmission distances and high output. Belt conveyors are widely used for material transport in the grain industry. This article briefly introduces its structural features and selection. A belt conveyor consists of a head drive section, transition troughs, line-changing troughs, intermediate troughs, push beams, a tail drive section, and scraper chains. (1) The single-link chain at the end of the scraper chain of the belt conveyor consists of a circular chain, a scraper, and link chains. Circular chains are made up of a series of products produced by conveyor chain manufacturers. The distance between the scrapers is determined based on the mode of transportation ； The polymer plastic scraper is integrated with the horizontal rings of the circular chain, with the flexible chain segments being connected by continuous rings. (2) Horseshoe-shaped rings are used for the belt conveyor coupling rings, making them easy to use. Longguang is made from high-quality alloy structural steel and goes through multiple processing steps, resulting in high strength and excellent wear resistance. (3) The selection of the belt conveyor speed should first be determined by the user based on factors such as the properties and condition of the material to be conveyed. (4) Selection of belt conveyor model: After determining the chain speed, an appropriate model can be chosen based on the conveying capacity. (5) Selection of power for belt conveyors: After selecting the model, the power and reducer, as well as the reduction ratio and type of components, can be determined based on the output volume, output length, and process layout.
