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].
The best ball mills, however, enable you to achieve the desired product quality quickly and efficiently, with minimum energy expenditure. That's what the FL ball mill is designed to do – with the added benefit of high flexibility. You decide whether to operate the mill in open or closed circuit, with or without a pre-grinder.
