The chart above illustrates the distance/length requirement for the level of incline on an inclined conveyor. In addition to a lower profile, the "L" and "S" configurations of the steep incline conveyor allow it to replace multiple pieces of handling equipment; one S-type steep incline conveyor can replace two belt conveyors and a bucket elevator, significantly …
All coal burned at the plant moves through a single chute. The path is at an angle of roughly 90 degrees from either of the discharging conveyors, making for a difficult transfer. A drop height of 30 feet also creates problems, including a large flow of induced air, resulting in dust escape, high levels of impact leading to idler damage and belt abrasion from poor …
Common belt conveyor problems include misalignment, belt slippage, and material spillage, which are often caused by improper installation, lack of maintenance, and wear and tear over time. This blog aims to provide comprehensive solutions to these conveyor belt problems through a detailed, downloadable PDF guide. By …

Eventually, it is fed to the boilers, again through a conveyor belt system. Coal from freighters is offloaded to the coal pile and fed to the plants using the same conveyor systems. Coal Pile Unloading: Coal Handling Pump Problems. Two key factors cause problems when handling coal. First, coal sinks in water. Second, water collects …
With the aim of solving the problem of coal congestion caused by big coal blocks in underground mine scraper conveyors, in this paper we proposed the use of a YOLO-BS (YOLO-Big Size) algorithm to detect the abnormal phenomenon of coal blocks on scraper conveyors. Given the scale of the big coal block targets, the YOLO-BS …
