摘要
用磨矿动力学参数和选择性破裂函数作为石英、磁铁矿有无选择性碎裂现象发生的判据;讨论了配比对它们的磨矿速率、粒级产率和新生比表面的影响.在磨纯矿物时、磁铁矿比石英易磨,磨矿速率相差较大;在磨纳混合物料时,两者之间存在相互干扰,并且这种干扰随磨矿细度的大小不同而不同,导致了磨矿速率差的减小.但粒度特性方程式却不受干扰.
Using the parameter of grinding kinetics and selecting brolen function to judge the presence of the selecting breaking in broken quartz and magnetite,we have studied the inference of rato ofquartz andmagnetite on grinding rate,the percentage of range of particle,size and new area of surface. Grinding puremagnetita is easier than grinding pure guartz.Mowever. when grinding the mixture of both magnetite andquarts、there exists interference in each other and the interference is different as the particle changes.
