Mineral Ore Ball Mill is horizontal type and tubular running device, has two warehouses. The ball mill is grid type and its outside runs along gear. The material enters spirally and evenly the first warehouse of the milling machine along the input material hollow axis by input material device. In this warehouse , there is a ladder scaleboard or ripple scaleboard, and different specification steel balls are installed on the scaleboard, when the barrel body rotates and then produces centrifugal force ,at this time , the steel ball is carried tosome height and falls to make the material grinding and striking. After grinded coarsely in the first warehouse, the material then enters into the second warehousefor regrinding with the steel ball and scaleboard. In the end, the powder is discharged by output material board andthe end products are completed.
