So, if the oven-dry sample weight will always be more than 1000 g (2.2 Ibs), the a scale that reads to 1 gram is very adequate. In general, we have found that a scale that reads to the nearest 0.1 g is what a mill needs for small samples.

The effect of speed was different in the two mills. For the Comil, except for fines (d10), generally, an increase in impeller speed lead to a decrease in particle size. Smaller particles showed higher sensitivity to impeller speed. For the hammer mill, the non-monotonic effects of speed were observed across different size cuts in the PSD.
