ABSTRACT:
A load zone area of a conveyor system which includes a continuous belt which carries bulk materials such as stone, ore, grain, etc. to a discharge point where the material leaves the belt as the belt wraps around a head pulley and returns along the under side of the conveyor system to a tail pulley which brings the belt back to a point which it can be loaded again. The load zone area typically has multiple support rollers closely spaced together to minimize the effect of the material impacting the belt which deflects the belt downward, thus creating a gap between the belt and the skirt seal causing leakage. The existing rollers normally have three rollers which form a "U" shape trough for the belt the two "wing" rollers are removed from the existing troughing roller assembly and replaced by a steel adapter to which a low friction rail may be attached longitudinally to the direction the belt moves, thus reducing the downward deflection of the belt where the material being loaded on to the belt is impacting the belt, and avoiding the gaps between the belt and the skirt seals.
