Abstract
Taking a Peru magnetite ore as the sample,experiments of relative grind-ability and bond work index of ball mill were conducted in order to evaluate the effect of the technology and equipment of the operation ahead of the grinding operation on subsequent grinding performance of ore.The results showed that when the target size of 106,74 and 45μm,the Bond work index of HPGR products was lower than that of the jaw crusher,but the Bond work index of pre-separating concentrates was higher than that of HPGR products,even higher than the jaw crusher products.When Bond ball mill work index was used to mill determine,the effect of the technology and equipment of the operation ahead of the grinding operation should be considered.With regrinding fineness of-74 μm 80%,the rel ative grind-ability of HPGR and JC product reached 0.90,the relative grind-ability of HPGR and pre-separating concentrates reached 1.23.The technology and equipment of jaw crusher,HPGR,and HPGR with pre-separating ahead of grinding,would lead to different performance of Ore.关键词
