The process involves crushing and grinding barite ore to reduce the desired size. It mainly involves using jaw crushers, impact crushers or cone crushers to reduce the size of barite raw material. After being crushed by these crushers, the size of the particles can be further reduced by grinding with a ball mill, raymond mill or other grinders.. …

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.
