摘要
针对锦屏水电站三滩大理岩加工性能差、破碎后原状砂石粉含量高的问题,采用三滩右岸砂石系统已有设备或新增工艺设备,在更宽的范围内开展了大理岩圆锥破、反击破和立轴破的制砂工艺试验研究。结果表明,不同类型的破碎设备在改变运行工况时,只对成砂率有影响,对原状砂的级配和石粉含量影响不大。其工程经验可为类似岩石制砂研究提供技术参考。
A large amount of test studies on marble sand processing technology are carried out in view of poor marble performance at Jinping I Hydropower Station,and the crushing equipments involve cone crusher,impacting crusher and vertical-shaft crusher.The results show that different type crushers can only influence sand ratio when operating conditions change,but hardly influence gradation of original rock and content of stone powder.The engineering experience can be a reference for similar researches.
