    Mechanisms of grinding modification by chemical

    1984-7-1  INTRODUCTION Past investigators have considered two major mechanisms to be mainly responsible 0032-5910/84/$3.00 267 for the observed effects of chemical additives on grinding= the first based on the reduction of surface-free energy of solids induced by the adsorption of surface active agents [1], the second related to changes in surface hardness due to the influence of the adsorbing species on the mobility of near-surface dislocations get price

    Mechanisms of Grinding Modification by Chemical

    2004-2-4  effect of chemical additives on the grinding process has been attributed to individual mechanisms. However, grinding is an integral process involving several simultaneous sub-processes such as transport of particles to and from the grinding zone, where they are subjected to different kinds of stresses. Evidently, such subprocesses depend on pulpget price
