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 …

Aggregate crushing is the process of breaking down the large pieces into smaller particles. Screening – different sized aggregates are required for different types of construction projects and materials – thus they need separating. Construction aggregates can also be produced from naturally occurring deposits such as sand and gravel.
