Abstract
A rock crushing and conveying apparatus for an open pit mining operation having an apron feeder conveyor, a rock crushing assembly and an endless belt drive station, each of which are capable of being lifted by a transporter vehicle and moved within the strip mine to different locations to reduce the amount of time lost in transporting raw material from the actual mining site to the rock crusher. The gyratory crusher is housed in a toroidal body mounted on three legs and elevated so that the underside of the body, which has a load bearing ring under the crusher, is accessible to said transporter vehicle.
