ABSTRACT:
A mobile stone crushing machine comprising a chassis on which is mounted a stone crushing unit and endless conveyor, a front end of which is adapted to collect stones from the ground as the machine is advanced over the ground, and from which the stones are continuously discharged into a stone crushing unit, characterized in that the stone crushing unit includes two crushing zones, each of which incorporates at least one crushing roller, so arranged that the stones to be crushed first pass through a nip associated with the roller at the first zone and on discharge from this nip the partially crushed stones and other matter then pass through a nip associated with the roller at the other zone. Preferably, the two crushing zones are arranged one above the other and each incorporates a pair of crushing rollers, one of which is rotatable about a fixed axis and driven and the other of which is supported upon a pair of trailing swing arms.
