在选厂设计中,国外多采用功耗法计算和选择破碎机、磨矿机。我国以往普遍采用以单位时间新生成合格粒级的量来表示磨矿的难易度,近年来也逐渐推广功耗法。功耗法的关键是测定邦德功指数,即单位产品的净功耗。作者对六个磷矿石样品做了破碎功指数和球磨功指数的测定,目的是为处理这些矿石的选厂的破、磨工序设计提供有价值的数据,同时也是探索这一方法在磷矿设计方面的应用。 In the plant design, the use of foreign power law to calculate and choose more crusher, grinding machine. In the past, China generally used to generate the amount of new grain per unit time to reflect the difficulty of grinding, in recent years, but also gradually promote the power law. The key to the power law is to measure the Bond Power Index, which is the net power consumption per unit of product. The authors made a determination of the crushing work index and the ball milling work index of six phosphate rock samples in order to provide valuable data for the design of broken and worn workpieces for the processing of these ores and at the same time, Design applications.
