Mineral Comminution and Separation Systems

Raw ore, or 'run-of-mine ore', is received by the storage 1 of the crushing plant for temporary storage, and then discharged through the feeder 2 for controlled rate of supply to the primary crusher 3, where coarse particles included are broken. The broken ore is conveyed to the secondary crusher 5 for further stage of crushing.
