5 Aggregate Production - IN.gov

CRUSHING The first step of processing begins after the extraction from quarry or pit. Many of these steps also are common to recycled materials, clay, and other manufactured aggregates. The first stag e in most operations is the reduction and sizing by crushing. Some operations, however, provide a step prior to crushing called scalping.
