流化床气流磨粉碎硅灰石针状粉的形状分析

Image Analysis for Wollastonite Powder With Needle Shape by Fluidized Bed Opposed Jet Mill

高长径比超细硅灰石的制备是硅灰石矿物加工技术的一个重要研究内容,而超音速气流磨在制备高长径比硅灰石粉体时具有优势。本文就流化床气流磨粉碎硅灰石的工艺中,通过对大量颗粒进行统计,初步得到硅灰石针状粉长径比与等体积直径的关系,以期能对硅灰石针状粉的制备起到一定的积极作用。

The preparation of wollastonite of high aspect ratio is an important matter of further procession of wollastonite ore. And the fluidized bed opposed supersonic show advantage in preparation of wollastonite of high aspect ratio. To make active sense in the preparation of wollastonite acicular powder of high aspect ratio, this article initiatively gained the relation between aspect ratio and isopyknic diameter of acicular powder in wollastonite shattering technology of fluidized bed opposed jet mill by the statistic of vast particles.
