用分级机改良传统雷蒙磨生产微细粉

Modification of ring rong mill with classifier for fine powder production

通过分析传统雷蒙磨的分析器和离心转子式分级机的工作原理，指出雷蒙磨分析器的缺陷和用来生产微细粉体的技术改造方案。通过在4R雷蒙磨上的具体改造试验数据。

By analyzing the working principles of the Ring RongMill separator and the eccentric rotator classifeir, the defaults of separater is pointed out and the modification with classifier for fine powder production are suggested. Through the experiments in the 4Rtype Ring Rong Mill, the possibilities and advantages of the modification are studied with the experimental data
