自F.C.邦德(F.C.Bond)的第三破碎理论于1951年发表以来,迄今已逾30年之久,然而在我国几乎仍未应用于破碎计算。共原因之一是我国的功指数测定工作跟不上,至今仍缺乏自己系统的各类矿石的测定数据。对此,笔者认为,有邦德的功指数测定数据,完全可以洋为中用。正如我们过去一直沿用K·A拉苏莫夫的资料一样。就某种矿石而言,无分中外,其可碎性是大致相同的。同样,共功指数也是大致相同的。 Since F.C.Bond’s third theory of crushing has been published for more than 30 years in 1951, it has almost not been applied to crushing calculations in our country. One of the reasons is that China’s work on index determination can not keep up. So far, it still lacks the data of various types of ore of its own system. In this regard, I believe that Bond’s work index measurement data, can be used as foreign. Just as we have always used the data of KA Ramsamov. In the case of some ores, the fragility is about the same for all types of ores. Similarly, the co-power index is roughly the same.
