Boulder Elimination System: Grizzly Feeder Integrated Jaw Crusher Setup
Controlling +1200mm Oversize in Copper Porphyry Mines
Massive sulfide boulders damage downstream equipment. OCP’s grizzly feeder integrated jaw crusher system handles 1,200-1,600mm feed with:
Step-deck grizzly with 300mm opening upper deck
Hydraulic flip-flow screen for mid-size separation
Dual-power jaw crusher (diesel/electric) with 1,800mm x 1,400mm inlet
Magnetite-lined discharge conveyor
Hard Rock Optimization Package
Boulder scanning LiDAR predicting feed composition
AI-powered gap control adjusting CSS from 250-400mm
Shock-absorbing mounting for uneven terrain
Dust encapsulation hood with negative pressure
