球磨机是选矿生产中的关键设备，其运行好坏直接影响着矿山生产能否正常进行。球磨机的简体连同其中的钢球矿石由两端的中空轴颈支承在滑动轴承上，负载重，良好的润滑尤显重要，否则容易出现轴承烧瓦而抱死中空轴颈的重大停机事故。大型球磨机一般都采用油泵循环供给润滑油的 Ball mill is the key equipment in the production of dressing, its operation is a direct impact on the normal operation of mine production. Ball mill simplified with one of the steel balls from both ends of the hollow shaft bearing journal bearing, heavy load, good lubrication is particularly important, otherwise prone to bearing bush and lock the hollow shaft major downtime accident. Large ball mill pumps are generally used to supply lubricants
