针对Φ3.2×3.1m格子型球磨矿分级系统中螺旋分级机故障率高,磨机电耗高,分级作业消耗大量清水资源等缺点,提出了Φ3.2×3.1m格子型球磨矿分级系统改进方案和措施,满足节能环保的需要。实践证明,改造后Φ3.2×3.1m格子型球磨矿分级系统运行稳定,故障率低,维修工作量小,磨矿分级指标提高明显,节能环保效果明显,取得良好效果。 According to the shortcomings of high failure rate, high mill power consumption and large amount of clean water resources in grading operation of Φ3.2 × 3.1m grid type ball milling and grading system, the improvement of Φ3.2 × 3.1m grid ball mill classification system is proposed Programs and measures to meet the needs of energy saving and environmental protection. Practice has proved that after the transformation Φ3.2 × 3.1m grid ball milling grading system is stable, low failure rate, maintenance workload is small, grinding grading index increased significantly, energy saving effect is obvious, and achieved good results.
