Grinding in Ball Mills: Modeling and Process Control

There are three types of grinding media that are commonly used in ball mills: • steel and other metal balls; • metal cylindrical bodies called cylpebs; • ceramic balls with regular or high density. Steel and other metal balls are the most frequently used grinding media with sizes of the balls ranging from 10 to 150 mm in diameter [30].
