Working Principle & Operation. The apparent difference in capacities betweengrinding mills(listed as being the same size) is due to the fact that there is no uniform method of designating the size of amill, for example: a 5′ x 5′Ball Millhas a working diameter of 5′ inside the liners and has 20 per cent more capacity than all otherball millsdesignated as 5′ x 5′ where the ...
Reliable and effectivegrindingtechnology for diverse applications. With more than 100 years of experience in developing this technology. Metso has designed, manufactured and installed over 8,000balland pebblemillsall over the world for a wide range of applications.
The circuit consists of a twocompartment ball milland a dynamic air classifier. There is a slotted diaphragm inside theball millthat separates the two chambers from each other. The particles coarser than the size of the slots (10 mm) stay in the first chamber while the finer particles pass the second chamber for further size reduction.
The HighEnergy Ball Mill Emaxand MM 500 were developed forgrindingwith the highest energy input. The innovative design of both, themillsand thegrinding jars, allows for continuousgrindingdown to the nano range in the shortest amount of time - with only minor warming effects. Theseball millsare also suitable for mechano chemistry.
Thegrindingcharge in aball millconsist of cast or forgedsteel balls. Theseballsare fed together with the feed and consequentlyball millscan be in operation for months without stopping. Theballsize is often in the diameter range of 20-75 mm. The biggest size is chosen when themillis used as a primarygrinding mill.

Mar 29, 2019·Ball millsare a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using aball mill.
