Belt Conveyor Rubber. PT. PAVA MANDIRI MAKMUR manufactures sidewall belts for various needs. Sidewall belts for batching plants, sidewall belts for stone crushers, sidewall belts for chemical plants, and various other industries. A sidewall belt conveyor is a type of conveyor that has vertical or inclined sidewalls attached to the edge of the belt. These sidewalls serve to retain the transported material and prevent spills, thus enabling efficient bulk material transport. Sidewall belt conveyors are commonly used in applications requiring horizontal, vertical, or inclined material transport. These belts are particularly useful in situations with limited space or where material needs to be contained within the conveyor system to prevent spillage or loss. We manufacture sidewall belts for a variety of applications.
