A major ball mill manufacturer presents a persuasive case for choosing this proven — and improved — design over other types

Over many years of use, shell-supported ball mills similar to those pictured above have proven their efficiency and reliability, and a large number of mining projects would not have been viable without them. A large and increasing number of references show that shell-supported ball mills work efficiently and reliably under the most stringent operating conditions. Their design advantages have earned them wide acceptance in the minerals industry, where they are used to grind copper, gold, and silver ores and other hard-rock materials.

Shell-supported mills comprise a steel cylinder, which is attached to the end walls. The mill cylinder is supported on two integral slide rings. Each bearing assembly consists of four to six white metal-coated sliding shoes, allowing the cylinder to rotate.
