A mobile rock crusher for crushing raw rock material which has been windrowed on a roadway in the translation path of the crusher includes a rigid supporting structure, which includes a frame, and translation means for allowing translation of the frame over the roadway. A selectively actuable scoop is pivotally mounted to the frame for selectively actuable lowering over the roadway into sliding engagement with, so as to collect, the windrowed raw rock material onto the scoop. A first conveyor is mounted to the frame. An upstream loading end of the first conveyor cooperates with the scoop for conveying the raw rock material from the scoop onto a first screen at a downstream depositing end of the first conveyor. The first screen is for screening larger diameter material from smaller diameter material in the raw rock material so that the smaller diameter material falls through the first screen. The larger diameter material translates over the first screen so as to fall into a first crusher mounted to the frame beneath the first screen. A second conveyor mounted to the frame beneath the first crusher is for conveying crushed material from the first crusher into a second crusher mounted to the frame for crushing the crushed material for deposition from the second crusher onto the roadway.
