周期式搅拌球磨机是一种新型高效超细粉碎设备。本文研究了球磨机制备超细重钙粉过程中球料比、矿浆浓度、介质种类以及磨矿时间对制粉效果的影响 ,提出了适宜的工艺参数。结果表明 ,用球磨机可制得粒径小于1μm的超细重钙粉 ,且产品粒度分布窄 ,磨矿效率高 ,工艺简单。
Periodic mixing ball mill is a new type of high efficiency ultrafine grinding equipment. In this paper, the effects of ball ratio, slurry concentration, media type and grinding time on milling efficiency in the process of preparing superfine heavy calcium powder were studied, and suitable process parameters were proposed. The results show that ultrafine heavy calcium powder with particle size less than 1μm can be obtained by ball mill, and the product has narrow particle size distribution, high grinding efficiency and simple process.
