used in a high-tension area of the belt. this is usually the driven pulley. the driven pulley may be at the head end, the tail end, or, with a center drive, anywhere along the return side of the conveyor. In these high-tension areas, the additional diameter in the center of the pulley adds additional stress to the center of the belt and mayextended a minimum of three belt widths past the load point. rules for conveyor and load point design should be used for guidance only, with transfers custom-designed to suit a particular project. It goes without saying that clean plants have lower operating costs. crushers, screens and dust-collection fans all contribute to high noise levels.
