超细粉碎分级系统设计与实验研究

Design and experimental study of superfine crushing and grading system

针对目前超细粉体制备中存在的问题,分析了ACM冲击式粉碎机的粉碎机理和SCX型超细分级机的工作原理,设计了新的超细粉碎分级系统。实验表明:对中低硬度矿物的粉碎分级,产品粒径小于15μm的占80%以上,小于30μm的占90%以上,平均粒径在10μm以下。

In order to overcome the shortcomings of existing superfine powder manufacturing process, a new superfine crushing and grading system is designed by analyzing the working principles of impact crusher ACM and superfine classifier SCX. The results show that ,when this system is used to crush and grade the medium or low hardness ores,the percentage of the superfine powder with particle size of less than 15 μm is above 80% ,and the percentage of that with particle size of less than 30 μm is above 90%. The mean particle size is below 10 μm.
