cohesive ore crushing

    • Crushing

      Ore crushing is a process of destruction minerals pieces into smaller by the action of the external forces, which overcome the internal cohesive forces between the particles. Сrushing is based on external forces – stretching, compression, shifting, bending, that impact on weakened section of the piece. For the ore crushing such features as strength and ...
