A crushing plant is carried on one trailer and a screening plant is carried on another trailer. A separate hopper for receiving material is supported on the crushing plant trailer. The trailers are positioned angularly with respect to each other. Conveyors on the trailers cooperate to move crushed material from a crusher to a screen. The screen classifies material and adequately crushed material is removed. Insufficiently crushed material is returned by conveyors to the crusher. The conveyors and other components are movable to permit transport of the trailers over public roadways.
