The equipment has a large amount of used sand cooling, reliable rain water cooling, low energy consumption, good dust removal effect and low noise.

Roller cooling bed includes roller, sand collecting cover. The transmission mechanism consists of motor, reducer, triangle belt and gear. When used, the whole drum cooling bed is placed in the pool, the outer wall of the drum is immersed in the water, the heat exchange is realized by using the specific heat capacity of water, the cooling water in the pool is constantly circulated to ensure cooling and cooling, and the sand is constantly turned over in the drum to improve the heat exchange rate.
