    Grinding balls buy metal balls from Metinvest manufacturer

    A ball mill is a drum-grinding unit where balls from solid materials (steel, iron, hard alloys, ceramics, etc) are used. Most common are ball mills, where when the drum rotates and the balls rub against the inner walls, the balls are lifted until the lifting angle becomes bigger than the angle of repose. Then the grinding media are again below. read more

  • Wet Autogenous Grinding in Tumbling Mills

    Wet Autogenous Grinding in Tumbling Mills

    Jul 04, 2019 The cause for this behavior is that the charge movements are impeded when the mill fills up. This effect will further decrease the abrasion rate and in this way enforce the charge swelling caused by a decrease in ore grindability. The mill will therefore loose its self-regulating, property and become instable in this region. read more
