Aggregate manufacturing typically starts by blasting rock masses and is followed by a series of crushing stages. Comminution in typical hard rock quarries is sketched in Fig. 1.ASTM particle size distributions of select aggregate products are also shown in Fig. 1 (ASTM, 2000).Crushing operations can accommodate some adjustment …

The Hilbert transform is a convolution that shifts the phase of a signal by −π/2, which results in a real and imaginary part of the analytic signal ( Feldman, 2011) Let x ( t) be a single component oscillation signal, and its Hilbert transform is given by Eq. (6). (6) x h ( t) = 1 π ∫ - ∞ ∞ x ( τ) t - τ d τ.
