The latter trips the conveyor if metal is detected. Secondary crushing comprises a Nordberg GP200 cone crusher operating in closed circuit with a screen. Feed from the primary crusher is screened to remove final product, nominally -16 mm, and the oversize gravitates to the cone crusher.
When used underground, jaw crushers are commonly used in open circuit. This is followed by further size reduction in crushers located on the surface. When the run of mine product is conveyed directly from the mine to the crusher, the feed to the primary crusher passes under a magnet to remove tramp steel collected during the mining operation.
