一、引言球磨机具有结构比较简单、单体容量大、破碎比高、产量大、连续运行性能好等优点,成为目前细磨的一种主要设备,广泛地应用于选矿、水泥、陶瓷和化学工业。长期以来,人们一直在致力干改进和完善球磨机的工作性能,但迄今为止,能量消耗高、作用效率低仍然是球磨机的主要缺点。如果将压应力 I. INTRODUCTION The ball mill has the advantages of simple structure, large monomer capacity, high crushing ratio, large output and good continuous running performance. It has become a major equipment for fine grinding and is widely used in mineral processing, cement, ceramics and chemical industries . People have long been devoted to improving and improving the performance of ball mills. However, up to now, high energy consumption and low efficiency inevitably remain the main disadvantages of ball mills. If compressive stress will be
