人们作了长期的努力以求降低湿式滚筒式磨矿机的高能耗。有论文报道,湿式磨矿作业利用化学添加剂来改变矿石特性以改善矿石的可磨性。据此,本文作者对印度磁铁矿石和不同的添加剂进行了扩大试验,以证实上述观察结果。用氧化钙作添加剂可获得显著成效。从电子显微照片上可以看出,氧化钙使矿石的石英组分表面造成的腐蚀和蜂窝状结构,使石英变脆而较易于研磨。 Long-term efforts have been made to reduce the high energy consumption of wet drum mills. There are papers reported that wet grinding operations use chemical additives to alter the characteristics of the ore to improve the grindability of the ore. Accordingly, the author of the Indian magnetite ore and different additives were expanded to confirm the above observations. With calcium oxide as an additive can be significant results. It can be seen from the electron micrograph that calcium oxide causes corrosion and honeycomb structure on the surface of the quartz component of the ore, making the quartz brittle and easier to grind.
