Claim Text:
1. A hydraulic injection milling system with classifying screen comprising a jaw crusher including a jaw crusher housing containing an eccentric shaft mounted in an eccentric bearing, said jaw crusher disposed to receive ore and communicate crushed material to an impactor by an auger, said impactor further comprising: an impactor housing comprising: a screen assembly disposed underlying the delivery aperture, said screen assembly further comprising: an impactor arm assembly rotatably disposed inside the impactor housing, said impactor arm assembly further comprising an axle having a first end and a second end rotatably mounted in a respective one of the pair of axle apertures, and a plurality of impactor arms radially disposed thereabouts, said impactor arm assembly rotatable to reduce the crushed material communicated to the impactor down to specific sized particles transmissible through the classifying screen; and an impactor shaft drive pulley in operational communication with the impactor arm axle second end; wherein hydraulic pressure internal to the impactor housing forces reduced material, degraded by action of the impactor arm assembly, through the plurality of elongate apertures disposed upon the classifying screen to the delivery chute for sorting and recovery.
