Troughing Set

Troughing idlers are found on the carrying-side, along the length of the conveyor. On any particular conveyor these idlers are identical, as are the bases. The troughing idlers comprise a centre idler roll of a defined width, and ‘wing’ idlers on either side of the centre roll. Unlike the centre, horizontal roll, the wing idlers are cranked up to a predetermined angle known as the troughing angle. This troughing angle ensures that the carrying belt maintains the same cross-sectional area throughout the carrying strand, so that the load-bearing capacity of a particular conveyor belt is the same along the conveyors’ full length. In so doing, material loaded to the maximum capacity at the loading point will not fall off of the belt en-route.
