摘要
球磨机钢球的充填制度对磨矿产品的细度、泥化程度,磨矿功效都会产生影响。本次试验研究针对陕西某氧化铅锌矿的性质特点,主要从钢球的充填量、不同钢球尺寸配比两方面进行磨矿技术研究,检测磨矿功效及泥化程度,找到较佳的钢球装填制度。最终确定的较佳的磨矿条件为:钢球尺寸30mm、29mm、27mm、18mm、15mm,钢球的重量百分配比依次为15.89、5.51、46.56、19.4、12.64,钢球的充填量为10.56kg。这样的钢球充填制度磨矿功效高,磨矿产品的泥化程度相对小,有利于提高选矿指标。
The steel ball filling system of the ball mill has influence on the grinding fineness, argillization degree grinding efficiency. Directed at the properties of this ore, through the two aspects of the filling amount and the of different size of balls, the research on the grinding technology, grinding efficiency and argillization degree was ried on to find the optimal filling system. As a result, the optimal grinding condition was determined as the steel size of 30mm,29mm,27mm, 18mm, 15mm and the ratio of the ball weight as 5.89,5.51,46.56,19.4,12. Meanwhile ,the filling amount is 10.56 kg. This kind of filling system has the characteristics with high grinding ciency and low degree of argillization, benefiting for improvement of the mineral processing index. and ratio car- ball 54. effi-
