摘 要

摘 要

球磨机是通过圆筒内的钢球在材料之上作用来碾磨材料的，是一种能有效的碾磨多种材料的工具。其被广泛地被用于建材、化工、选矿等行业。

球磨机的能量利用率很低，这和物料在磨内分布情况有极大的关系。越靠近筒体的外层运动轨迹，研磨作用越大。而磨机实际生产时，物料进入筒体就直接落入内层，内层的物料要经过较长时间才能进入外层充分碾磨，从而损失了大量能量。

为了使物料合理地分布，对磨机进料部分进行改进。将旧式的直角下料溜改为倾角式下料溜，使物料溜角大于休止角，物料顺畅进给。合理的选取进料点，使物料直接进入筒体外层。最后通过计算和一些经验数据，确定进料装置的材质，物料填充率，筒体适应转速和磨机功率等相关参数。

Abstract

Ball mill winch grinds material by rotating a cylinder with steel grinding balls, is an efficient tool for grinding many materials into fine powder. It is widely used in building material, chemical industry, etc. A Ball Mill

The ball mill energy use factor is low, the distribution situation has the enormous relations with the material in grinding. Therefore discovered more approached the grinding machine outer layer, the abrasive action is bigger. When grinding machine actual production, the materials entered the mill to fall directly the inner layer, the process dynamics analysis, the inner layer material had to through the long time to enter the outer layer, reduced the production efficiency greatly.

In order to cause the material to be quickly even, it has made the improvement to grinding machine feeding. First the old-style right angle feeding change the inclination angle type, then slide the angle to be bigger than stops the angle, will cause the material fast smoothly to enter. Then reasonable selection feeding spot, causes the material to enter the tube body outer layer directly. Finally through the computation and empirical dates, had determined the device material, the material feeding rate, the mill the rotational speed and the grinding machine power and so on.
