摘要
干法生产超细粉是我国非金属粉体的重要加工工艺之一 ,传统的粉磨设备难以达到大量生产d97=2～ 10 μm超细粉的要求 ,且生产效率低。阐述了采用多磨轮、多磨道原理设计的GYM - 83型亿丰磨在生产粒径为 11μm的碳酸钙干粉时 ,其累积分布达 98% ,粒径为 2 μm的占总质量 4 4 96 % ,产量达到了 12 5 0kg/h ,且基建投资少 。
It is one of the most important processes to produce super fine powder in dry method.It is very difficult for the traditional pulverizing equipment to produce qualified d97=2～10 μmsuperfine powder and the production efficiency is very low.The GYM-83 Yifeng mill,whith is designed multi-grinding wheel and the multi-grinding track ,is described.Using this mill to produce 11 μm particle sixe calcium carbonate powder,the cumulative distribution can be up to 98%,among which the 2 μm product can be up to 44.96% of the total,and the production capacity can reach 1 250 kg/h.It has advantages of low investment and high performance-cast ratio.
