Coarse crushing includes crushing operations discharging at sizes 4- to 6-in. or coarser; intermediate crushing comprises operations taking feeds 6- or 8-in. maximum and making products down to -1/2″ or 3/8″. Fine crushing is reduction by crushing to 1/4″ or finer; the distinctions are not sharp.
So when implementing real time control of a crushing plant, a measurement of the status in the actual process is crucial. However, it is difficult to measure product properties in real time at a plant due to several factors, e.g. the high capacities, the dirty environment, and the wide range of product sizes.
