Ball Mills. Ball mills originally were used to grind approximately 2 in. material to pass 10 to 80 mesh screens. Present day practice is to use a feed of about 1/2 in. or finer. Product size has become increasingly finer and no actual grind limit is indicated.

Ball mill is a high-energy mill process especially used for an energy-intensive process like mechanical alloying, mechanochemistry, or mechanical activation. Planetary ball mill is used to determine the dependence of process efficiency using milling parameters such as ball size and number, mill geometry, and velocity of the rotating parts.

defects formation, particle size reduction, local melting, and even phase changes to other polymorphs []. Ball mill is generally preferred to grind the solid reactants, since it can supply high power, being programmable, and result in smaller particles with small polydispersity [].

Then 5 g portions of the powder were placed in a locally built ball mill (Forziati et al. 1950) running at 1750 rpm. The approximately one liter steel jar was chromium plated and 500 mL of stainless steel balls 0.25 in. (~ 6 mm) in diameter were employed. This is considered to be a "vibratory" ball mill in contrast to the planetary type.

Industrial mills are used to change the size of a product, whether by breaking or grinding a material into smaller granules or powder or by agglomerating a product into larger granules or pellets. Roller mills use rollers to crush the product into a smaller granule or powder. An attritor mill wears the product into a smaller size.

The Azzaroni equation indicates that the correct ball size for the 2.93 m mill is 81 mm. Years of experience show that a 76 mm ball grinds the coarse particles most effectively. Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the cross-section of the balls charged to the mill.
