Single Stage Crushing

Single-stage crushing is generally employed where the final product size of the ore being crushed is generally between 90mm to 200mm.

Single-stage crushing circuits are generally configured in an open circuit arrangement, that is what goes into the crushing machine exits and goes onto its final destination. There is no recirculating load or screening involved.

The size of the product leaving this stage is controlled by the size of the discharge opening or closed side setting of the crusher.

Primary jaw and gyratory crushers are generally configured in an open circuit arrangement. A scalping grizzly may be installed prior to the crusher to improve its performance and reliability by eliminating material being fed to the crusher already at the correct size.
