山东黄金三山岛金矿新立分矿氰冶厂使用的MQYφ2.1 ×3.0型球磨机,原为格子型,用于一段粗磨,1993年改为溢流型用于金精矿再磨,磨机主要参数见表1。氰化厂日处理量为150 t/a,磨矿细度要求-400目占95%以上,磨矿效果一直达不到要求。
MQYφ2.1 × 3.0 type ball mill used in Xinyingsha Mine of Xintiao Mine of Shandong Gold Sanshijin Gold Mine was originally of a lattice type for rough grinding in 1993. It was changed to overflow type in 1993 for the gold concentrate regrinding and grinding Machine main parameters in Table 1. Cyanide plant daily processing capacity of 150 t / a, grinding fineness required -400 heads accounted for more than 95%, grinding effect has not met the requirements.
