一、引言球磨机问世一个半世纪以来,一直是细磨的主要手段。这种状况至少要持续到本世纪末。但是球磨机的工况并不令人满意,其主要缺点表现在高额能耗上。造成球磨机能耗高的原因是多方面的。首先球磨机的破碎条件属于料层破碎,不具备单颗粒的破碎性质,因此磨料颗粒之间的摩擦消耗了大量的能量。此外磨料的受力和移动是一个随机过 First, the introduction of ball mill come out a half century, has been the main method of fine grinding. This condition will last at least until the turn of the century. However, the condition of the ball mill is unsatisfactory and its main disadvantage is reflected in the high energy consumption. The reasons for the high energy consumption of the ball mill are manifold. First of all, the crushing conditions of the ball mill belong to the crushing of the material layer and do not possess the crushing properties of single particles, so the friction between the abrasive particles consumes a large amount of energy. In addition, the force and movement of the abrasive is a random over
