Figure 1
Upper part: example of three different PSD curves. Dotted and continuous lines correspond to PSDs belonging to the kth and jth phases, whose particle diameter does not exceed the d1 limit, whilst the dashed line corresponds to the PSD belonging to the ith phase, whose particles are also included in the d1–d2 range. Lower part: CPSD curves of a sample (including the same three phases) that has been ground for t1 (continuous line) and t2 (dotted line). The difference between the horizontal-line-filled area and the vertical-line-filled area equates to the loss of volume of the ith phase in the d1–d2 range, in the t1–t2 interval. |
