  • Cement millWikipedia

    A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel.The smaller grades are occasionally cylindrical ("pebs

  • Flexible milling and grinding solutions that last FL

    For the mining industry our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold copper and platinum industries as well as in the lead zinc silver and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.
