国家“六五”期间重点攻关项目SYD-200型露天矿液压碎石机由嘉兴冶金机械厂、长沙矿山研究院、北京钢铁研究总院、鞍钢齐大山铁矿于1985年6月共同研制成功。这种碎石机是我国首次研制成的大型高能液压碎石器,具有碎石和挖掘功能。它的技术性能好、破碎效率高,结构合理,达到了国外同种机器80年代的先进水平。碎石机可配用冲击能400～20000公斤力·米的各类高频、高能碎石器。碎石器单次冲击能为1700～2200公斤力·米、冲击频率15～20次·分~(-1)。承载机动力装
Key national key projects during the “6th Five-Year Plan” SYD-200 opencast hydraulic hammer was successfully developed in June 1985 by Jiaxing Metallurgical Machinery Factory, Changsha Mining Research Institute, Beijing Iron and Steel Research Institute and Anshan Qidashan Iron Mine. This lithotripter is the first large-scale high-energy hydraulic stone breaker developed in our country with gravel and excavation functions. Its technical performance is good, crushing efficiency, reasonable structure, reached the advanced level of the same type of foreign machinery in the 1980s. Crusher can be equipped with impact energy 400 ~ 20000 kg of power meters of various types of high-frequency, high-energy lithotripsy. Shock stone single impact energy of 1700 ~ 2200 kg m · m, impact frequency of 15 to 20 times · min ~ (-1). Carrying machine power pack
