Aggregate Processing. During processing, aggregates are distilled down to a level of their most common use. Some aggregates may be crushed to a powder while others may be screened to various diameter chunks. The proper processing of aggregates is important in maintaining their desirable qualities. For instance, between 60 and 75 …Web
