Mechanical activation of the phosphate rock

Mechanical activation of phosphate in highly intensive size reduction equipment, such as modified vibrating mill should result on an increase in degree of dispersion of the milled product (Gock and Jacob, 1984). Figure 4 illustrates the size distribution of the ground end products (after 90 min). Gradual increase in the %D90 values with increasing milling time for raw and concentrate samples is indicating theThe investigation was conducted with an aim to increase the reactivity of the comminuted phosphate ore and to establish the optimal mechanical activation period of the grain mixture.(PDF) The Effects of the Phosphates’ Mechanical Activation12/11/2015· The investigation was conducted with an aim to increase the reactivity of the comminuted phosphate ore and to establish the optimal mechanical activation period of the grain mixture. In order to obtain complete insight into the process and phenomena of the phosphate grain mixture activation, a good understanding of the theoretical principles of the activation operation is necessary.
