Mineral Processing Equipment for Mining Industry

After crushing, grinding refines ore into a fine powder to liberate valuable minerals. Key types include Ball Mills, which grind ore using steel balls in a rotating cylinder; Rod Mills, which use long rods for a coarser grind; and SAG Mills, which combine crushing and grinding for efficient processing of large volumes of hard materials.
