Ball mill. Ball mills Fig. 12.17 are short cylindrical vessels with a shell to diameter ratio of 1.5 to 1 and less. When the length to diameter ratio varies between 3 and 5 it is called tube mill. The grinding medium is high-carbon or cast alloy steel balls. The particle size of the feed usually does not exceed 20-25 mm. We provide a large number of solutions for customers in more than 160 countries/regions around the world, and are committed to creating the most suitable solutions for customers. We welcome your inquiry 7/24 hours.
