四川德阳东方电机厂建成了水爆清砂、旧砂再生全套设备。其工艺流程是:将落砂后温度为400～600℃的铸钢件,吊入水爆池,进行水爆。爆落的砂子,经格筛分选,落入有两个锥体的池底,大砂块及杂物则被阻止在格筛上,定期清除。池底的砂子由喷嘴搅拌成浆状,通过水力提升机送至中间池;经中间池上

Sichuan Deyang Dongfang Electrical Machinery Factory built a burst of clear sand, old sand regeneration complete set of equipment. The process is: After falling sand temperature of 400 ~ 600 ℃ cast steel, hanging into the water pool, water explosion. Broken down the sand, the grid sieve, falling into the bottom of the pool with two cones, large sand block and debris are blocked in the sieve, regularly removed. The sand at the bottom of the pond is stirred into a slurry by a nozzle and sent to an intermediate pond through a hydraulic elevator;
