Secondary & Tertiary Crushing Circuits

This one involves both SECONDARY and TERTIARY crushing. This circuit is employed where either the tonnage or the work index of the ore is high enough to require that the crushing be done in stages. Again the ore will come from a Primary crusher and be scalped. The coarse material will be crushed by the secondary crusher.

An investigation into the fragmentation of blasted rock at

The crushing plant utilization increased from an average 91.5% when using the old blast practices to 96.3% with the new blast practices. When calculating the crushing plant's utilization, only downtime due to jaw crusher blockages (as a result of oversize entering the jaw crusher) was taken into account-all other downtime was excluded.

Working Principle of Crushers

Gyratory Crushers are heavy-duty machines run in open circuit (sometimes in conjunction with scalping screens or grizzlies). They handle dry run-of-mine feed material as large as 1 m. There are two main types of primary crushers-gyratory crushers and jaw crushers. Gyratory crushers are the most common for new operations.
