Gyratory and Cone Crusher
Usually, a grizzly is placed prior to the feed entering the crusher to remove extra large pieces, which tend to jam the operation. Gyratory Crushers are invariable operated in open circuit. When a choice has to be made to include a gyratory or a jaw crusher in a circuit, a general rule of thumb is to examine the desired production rate.

The basics of crushing | Pit & Quarry
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 ...
