Belt conveyor is the transportation of material from one location to another. Belt conveyor has high load carrying capacity, large length of conveying path, simple design, easy maintenance and high reliability of operation. Belt conveyor system is also used in material transport in foundry shop like supply and distribution of molding sand, molds and removal of waste. In this paper the study is carried out on DISA pattern moulding machine to meet the requirement of higher weight castings. The DISA machine is having the capacity of 100 moulds per hour. The mould size and density of material is given parameters. The present discussion aims to design the conveyor system used for cooling of mold, which includes speed, motor selection, belt specification, shaft diameter, pulley, idler spacing, gear box selection, with the help of standard practice and these results are verified with the belt comp software.
