Introduction to Mineral Processing or Beneficiation
Many older operations have rod mills in combination with ball mills. Ball mills are a similar shape to that of the rod mills except that they are shorter with length to diameter ratios of 1 to 1.5. As the name implies, the grinding media in these mills are steel balls. The particles size of the feed usually does not exceed 2.5 cm.
