Abstract:

A riprap separation apparatus and method which riprap apparatus comprises a frame having an open space within the frame, an upper grizzly section composed of a tiltable upper grizzly section having a plurality of fixed, spaced apart bar elements so that riprap material discharged onto the grizzly section is separated into a large size material and a smaller size material which passes through the bar elements and a downwardly angled discharge chute to receive the larger size material and to deposit the large size material to one side of the apparatus. The apparatus includes a support section disposed to be within an earthen sloped access ramp to provide support for the apparatus and with the ramp to provide for the movement of vehicles to discharge riprap material into the grizzly section.
