矿石的球磨可磨度的测定方法和程序各国不尽相同。苏联和东欧部分国家采用容积比较法。其不足之处在于,它必须积累大量生产实践数据和经验,没有直接反映被磨物料本身的性质,也没有反映出磨矿产品与能量消耗之间的关系。北美、北欧和日本等国采用邦德(Bond)功指数法测定和表示矿石球磨可磨度,并以此进行球磨机功率的选择计算。我国从七十年代末期也开始了邦德球磨功指数测定方法 Ore ball mill grinding method and procedures can vary from country to country. Some countries in the Soviet Union and Eastern Europe adopted the volume comparison method. The disadvantage is that it has to accumulate a large amount of production practice data and experience, does not directly reflect the nature of the material being milled nor does it reflect the relationship between grinding products and energy consumption. North America, Northern Europe and Japan and other countries using Bond (Bond) index method to measure and indicate that the ores can be grinding degrees, and to choose the ball mill power calculation. From the late seventies in our country also began the Bond ball mill index determination method
