    Types of OperationsTypes of CrushersCompression Crushing Quick FactsImpact CrushingImpact Crushing Quick FactsCrushing EfficiencyThere are two types of aggregate operations: open circuit and closed circuit. An open circuit operation is where feed material is only run through the crusher once. This usually occurs in a primary and sometimes secondary operation where uniformity of product size is not as critical. A closed circuit operation is where material is continuously returned to the crusher until it’s of a size that will pass through the product screen.See more on pitandquarry
