An experimental study was performed to characterize two continuous mills for their ability to mill aluminamagnesia extrudates. The effect of mill parameters, namely, the screen aperture size, and impeller speed on the particle size distribution of the milled product was quantified for a conical screen mill and a hammer mill. In general, the conical screen mill was found to be more sensitive ...
