To fully dissociate useful barite minerals, ball mills are commonly used to grind barite rocks. Generally, the grinding fineness of barite200 is 85~90%, and a twostage grinding process is often used. In view of the differences in the properties of barite ores, the optimum grinding fineness needs to be determined experimentally.
