conveyor belt is normally referred to as the 'carcass.' in a sense, the carcass is the heart of the conveyor belt since it must: 1. provide the tensile strength necessary to move the loaded belt. 2. absorb the impact of the impinging material being loaded onto the conveyor belt. 3. provide the bulk and lateral stiffness
conveyors flat and troughed flat belts many bulk materials can be carried on flat belts. flat belts are particularly com-mon for materials with a steep angle of repose, the angle that a freely formed pile of material will make. materials with angles of repose above 30 degrees are ma-terials suitable for flat belts
