Bulk material conveyors are necessary in steel mills to transport large quantities of materials such as coal, coke, aggregate, stone and powders from one location to another within the mill. A belt conveyor uses a rubber or chain link belt supported most often in a v shape roller arrangement. The top of the conveyor is open and the series of roller conveyors may be hundreds of feet long. A drag conveyor utilizes an enclosed steel rectangular box which has a series of drag links, which slide against the inside walls of the rectangular box to move the material in a vertical motion. Belt and drag conveyors are rated by the amount of material they can convey per minute or hour. Contact Casey Equipment for a quote on used bulk material conveyors for sale.
