在成批、大量生产的铸工车间,为了确保正常生产,混砂机除应满足工艺要求外,还应该是运转可靠、经久耐用和便于维修。S116A 型辗轮式混砂机是我国较早试制的高效率混砂机,由一机部济南铸锻机械研究所设计,上海热加工机械厂制造。我厂机械化铸造车间采用了二台 S116 In bulk, mass production of the Casting Workshop, in order to ensure the normal production, in addition to sand mixer should meet the process requirements, but also should be reliable, durable and easy to maintain. S116A type roller wheel sand mixer is trial production of high efficiency sand mixer in China, which is designed by Jinan Casting Machinery Research Institute of a machine department and manufactured by Shanghai Heat Processing Machinery Factory. I plant mechanized foundry used two S116
