Cooling drum for mold shaking, casting cooling and sand recycling Belloi Romagnoli

The sand and casting cooling drum has been devised to offer modern foundries the possibility to cool sand and castings at the same time, to ease castings cleaning and to control the quantity of fines by means of an appropriate suction.
Obviously, the utilization of a sand and casting cooling drum is to be valued according to the production typology and to its undeniable advantages on the process.
Poured moulds are taken from shakeout to drum by means of a vibrating conveyor. The cooling process is based on the evaporation of the residual moisture of return sand and on the evaporation of the water appropriately added by a conditioning device, which is made up of two parts: one part adds water into the charging area (according to incoming temperature) and the other part adds water into the sand discharge area, if necessary.
