强化节能降耗措施 提高磨矿分级技术水平

Intensification of the Energy saving,Consumption reducing Measures and Improvement of the Grinding classification Technological Level

磨矿是矿山生产中能耗最高的工序，提高磨矿分级技术水平对于矿山有重要意义。本文从强化预选、多碎少磨、应用耐磨材料和强化分级三个方面论述了国内外磨矿分级的现状，探讨了我国冶金矿山磨矿分级的发展方向。

Grinding is the biggest energy consumption process in mine production.Improvement of the grinding classification technological level is of great importance.In terms of pre concentration strengthening,more crushing and less grinding,abrasive resistant material usage and classification intensification,the paper describes the present situation of grinding classification both in and outside China and discusses on the development orientation of grinding classification in China's metallurgical mines.
