抛砂机是以高速旋转的叶片,将型砂抛入砂箱,得到坚实的铸型的一种造型机械。它以机械代替人工加砂与捣实,也甩掉了笨重的风动冲砂器之类手工具。一般每小时可抛砂12～25立方米,比手工生产效率提高3～10倍。这就大大地提高了劳动生产率,减轻了工人劳动强度。 Sand thrower is a high-speed rotation of the leaves, the sand thrown into the sand box, a solid mold to get a molding machine. It is a mechanical alternative to artificial sanding and tamping, but also get rid of bulky pneumatic scouring and the like hand tools. Generally hourly throwing sand 12 ~ 25 cubic meters, than the manual production efficiency increased by 3 to 10 times. This has greatly increased labor productivity and reduced the labor intensity of workers.
