利用重心平衡原理实现球磨机的节能设计
|
摘要
为了减小球磨机因物料重力偏心运行造成的动平衡差和功率损耗大的问题,将球磨机的单筒单重心结构设计成多筒多重心分散结构形式,利用各筒的重心平衡作用,消除了由于偏心距引起的能耗做功。经几何结构的理论推导和计算可知,筒体数量达到3个以上,同时各筒体的物料质量相同,其平衡原理成立,可减少大约40%以上电动机的动力配置,同时也使球磨机的整体平衡性得到了提高,达到了真正意义上的节能、减排、环保、增效的目的。
To relieve the poor dynamic balance and large power loss of the ball mill caused by off-center operation due to the gravity of charge, the paper changed the structure of the ball mill from single cylinder and single center of gravity to multiple cylinders and multiple centers of gravity. The balance of the centers of gravity of various cylinders eliminated the energy consumption due to eccentricity. Theoretical deduction and calculation of geometric structure showed, when the number of the cylinder was more than 3, and there were the same mass of material in each cylinder, the balance principle set up, more than 40% of power of motor reduced, meanwhile the overall balance of the ball mill enhanced, thus real energy saving, emission reduction, environmental protection and efficiency enhancement were achieved.
