Fine grinding: How mill type affects particle shape characteristics …
The breakage mechanisms in stirred mills – regardless of the mill orientation – are typically described as abrasion and attrition (Gao and Forssberg, 1995, Sinnott et al., 2006, Wills and Napier-Munn, 2006, Ye et al., 2010), or more simply "shear" breakage (Radziszewski, 2013).The dominant breakage mechanism in ball mills is generally …
Grinding Balls & Rods
Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding. A much higher grinding capacity is obtained in tube mills by using steel media instead of pebbles, but in making such a conversion serious consideration must be given to the ability of the steel shell to …
Grinding Balls and Other Grinding Media: Key consumables
Tower Mills: 0.5"-1.5" grinding balls are recommended. The normal top size of media used is 10-25mm, but even smaller grinding balls can be used for very fine grinding. Isa Mills: <0.1" grinding balls are recommended. The Isa Mill is more efficient when using small media (i.e. high-chrome steel balls).

Ball Mill (Ball Mills Explained)
If a ball mill uses little or no water during grinding, it is a 'dry' mill. 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 ...

Ball Mill
Thus in a given grinding circuit, for a certain feed rate, a pebble mill would be much larger than a ball mill, with correspondingly higher capital cost. The increment in capital cost might be justified by reduction in operating cost attributed to the lower cost of the grinding medium, provided this is not offset by higher energy cost per ton ...
