A conveyor at a coal plant in China was experiencing material return problems, the system conveyed hundreds of tonnes of coal slag on a 48 inch wide (1200 mm) conveyor belt at 300 fpm (1.524 m/s) from the mine to inside the surface facility, the outdoor portion of the belt, although covered, was exposed to extreme weather, the material was sticking to the return side of the belt, collecting on the around the mainframe and made the rollers sticky, requiring downtime for maintenance and increasing operating costs.

A coal mine factory in China is experiencing problems with the return of material on its conveyor belt. The system transported hundreds of tons of coal slag, which was transported on a 48-inch wide (1200mm) conveyor belt at a speed of 300fpm (1.524 m/s), from the mine to the surface facility. The outdoor portion of the belt, although covered, was also exposed to extreme weather. Material adhered to the return side of the belt, accumulated around the main machine, and made the rollers sticky, requiring downtime for maintenance and raising the cost of operation.
