摘　　要：本文探讨了湿式磨矿过程中钢球表面罩盖层厚度的影响因素及其影响规律。研究结果表明 ,钢球表面罩盖层厚度随矿浆体积浓度的增大而增大 ,且存在一临界值 (约为 5 0 % ) ,当矿浆体积浓度大于该临界值时 ,罩盖层厚度急剧增大 ,矿浆体积浓度越高 ,增大的幅度越大 ;添加化学药剂能改善高浓度矿浆的流变性 ,使钢球表面出现最佳罩盖层厚度所对应的矿浆体积浓度增大 ;当矿浆性质一定时 。Facfors influencing the thickness of pulp layer stuck on a steel ball in wet grinding mill are analyled in this paper.Results of research showed that the thickness of pulp layer stuck on a steel ball increases with the growth of volumetric density of pulp,and there is a critical point of about 50% for solids content.When the pulp density is over the critical point,the layer thickness increases rapidly.The thickness increases with growth of Blaine index of ore particle,and the higher the pulp density is,the more the thickness increases.Adding of chemicals can improve the rheological behavior of high density pulp,thus improving the performance of grinding.Under the condition that pulp property is constant,the speed of pulp flowing has no influence on the thickness of pulp layer stuck on a steel ball.
