前言磨矿机广泛应用于冶金、化工、煤炭、陶瓷等各个工业部门,因此,对于磨矿机的选择与计算各个部门也有不同的方法。对于冶金矿山而言,我国一直采用苏联使用的新生成级别法,而欧、美、日等国家则大多采用以邦德(Fred.C.Bond)第三破碎理论为基础的功指数(Work index)法。用功指数选择计算磨矿机的方法近年来我国已逐步开始掌握,但尚待应用于设计中,本文拟对功指数法选择计算磨矿机作较详细的介绍,以供采用此法者参考,并对功指数法存在 Preface Mill is widely used in metallurgical, chemical, coal, ceramics and other industrial sectors, therefore, for the selection and calculation of the mill of various departments have different methods. For the metallurgical mines, China has always adopted the new generation-level approach used by the Soviet Union, while most countries in Europe, the United States, Japan and Japan adopted the work index based on the third broken theory of Fred (C. Bond) )law. In recent years, our country has gradually begun to grasp, but has yet to be used in the design, this article intends to calculate the index method of grinding machine for more detailed introduction, for the use of this method for reference, And the power index method exists
