The Ball Tube Mill (BTM) is a cylindrical low-speed grinding mill. It consists of a steel barrel, lined with cast abrasion-resistant liners and partially filled with hardened steel balls. Coal and pre-heated primary air enter one or both ends of the mill from a crusher/dryer or feeder. As the mill rotates, the balls cascade and
If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be …
