How Troughing Idlers Work
Troughing idlers consist of three or more idlers that guide the conveyor belt. They are found on the carrying side of the belt and are installed along the entire length of the conveyor. The troughing idlers work to keep the belt in the same configuration all along its length, which thus maintains the same cross-sectional area as the belt carries mined materials from their source to the drop off point. A troughing idler is comprised of a central idler roll, which has a fixed width, and two or more wing idlers located on each side of the central idler roll. The wing idlers can be adjusted up or down to change the toughing angle, which affects the depth of the trough created by the conveyor belt as it moves.
Benefits of Troughing Idlers
Troughing idlers offer two important benefits. First, the troughing idlers keep the belt’s shape consistent throughout its journey, which improves both stability and carrying capacity. Second, troughing idlers reduce the amount of material that may accidentally spill over the edge of the conveyor system, which improves productivity and also increases the safety of workers, who may be at risk from falling material while working near conveying equipment.
