Comparative Performance of Beneficiated Runof ...
Mechanical Grinding (BallMilling) Grinding of the raw FA, is a simple, but rather crude, method of reducing the mean particle size. In this study, the raw FA was ground in a laboratory planetary ball mill, until the majority of particles, in this case >98% by volume, were finer than 45µm. Grinding required typically around 20 minutes for 200g ...
