Rod mill is extensively applied to metal and non-metal mines and water conservancy. The machine can be employed in tungsten and tin ores, along with other rare metal ores, so as to stop the damage of over grinding, they generally adopt rod grinding; when making use of two stages ore grinding progress, on the condition where the very first stage is grinding from between twenty and six mm to between three and one mm, adopting rod grinding as the ore grinding device of 1st stage, and then the manufacturing capability is really significant, also, the efficiency is in addition high. Due to the fact the surface square of certainty weight rod loadings is larger than the same weight ball loadings, so whilst you make use of rod grinding as the fineness grinding of second stage, then the manufacturing rate and efficiency will be both below ball grinding.
