CM51A型冲击式超细粉碎机的应用研究

Application of CM51A Impacting Pulverizer to Superfine Grinding

对CM51A型冲击式超细粉碎机的工作原理进行了分析,同时也讨论了影响粉碎设备性能的因素。该型粉碎机是利用高速运转的锤头,采用于法粉碎技术,对莫式硬度小于5的物料进行超细粉碎,通过对煤系高岭土、滑石、碳酸钙类矿物等多种矿物的生产实践和应用研究。生产实践表明,该设备配以分级设备后,最终产品粒度为1250目,产量200kg/h以上,除粉碎外,该设备还具有提高被粉碎物料的纯度和解聚打散的功能。

The characteristics of the CM51A impacting pulverizer for superfine grinding are briefly introduced. This type of the pulverization technology is dry method by using high-speed rotary hammers in the pulverizer. The materials which the Mohr' s hardness are less than 5 are suitable to be pulverized. The results of the application research and prodution experiment of the coal measure kaolinite, talc, calcium cardonate and so on show that the particle size of the superfine crashed products is 1250 mesh, the output is more than 200 kg/h when the separtor is equipped.
