Cylindrical zirconia or stainless-steel grinding media should be used for effective grinding of the powder. Union Process Attritor Mill. The attritor mill is a wet grinding attrition mill. It differs from conventional ball mills as it uses much smaller media with diameter less than 5mm, leading to greater media-material contact area.


Ball Tube Mill 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


Attrition mills use the hammermill principle to a certain extent; i.e., shattering by/impact. However, they also impart a shearing and cutting action. Grinding is done between two discs equipped with replaceable wearing surfaces. One or both of these discs is rotated; if both, they rotate in opposite directions.


Grinding media balls are manufactured from steel and cast iron. These are used as a medium in a Ball mill which is a horizontal cylinder partly filled with the media balls that rotates on its axis, imparting a tumbling and cascading action to the balls.Material fed through the mill is crushed by impact and ground by attrition between the balls.

A Grinding Ball Mill is a type of grinder used to grind and blend materials for use in mineral processes. A Grinding Ball mill works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.


Grinding balls can simply be dumped into the top of the feed pipe and they will be smoothly fed into the attrition mill by the action of the rotating disc. By feeding the grinding balls in on the rotating disc, the added advantage is obtained that these balls are thrown to the outside wall of the mill where they can sink down towards the bottom ...
