前言关于破碎能量的理论,很早以前人们就知道雷廷格和吉克法则。但自1952年F·C邦德提出所谓第三法则之后,该能量的理论在破碎流程设计或者操作管理方面才得以应用。本文只叙述有关球磨机粉碎的实例。式(1)计算的功能指数,用生产功指数表示,F与P分别为给矿及产品80％的粒度(微米),W为每吨矿石所消耗的电量千瓦·时/吨,W_i为功指数千瓦·时/吨。
Foreword On the theory of breaking energy, long ago people knew Remington and Gikh’s law. But since F · C Bond proposed the so-called third law in 1952, the theory of energy was applied in the design of crushing processes or operation management. This article only describes examples of ball mill crushing. The function index calculated by the formula (1) is expressed by the production work index, F and P are respectively 80% of the ore and product particle size (micron), W is the kilowatt hour / ton of electricity consumption per ton ore, W_i is the work Index kWh / t.
