5 Aggregate Production - IN.gov

After primary crushing/reduction the resulting aggregate generally is placed in a large "surge" pile where the aggregate may be fed into the secondary operation whenever convenient. Care is always taken when building up and loading out surge piles, as this step may be a major source of segregation of material going to the secondary plant.
