jul 01, 2003 figure depicts the effects of media size on grinding times. from this plot, it is shown that a target fineness of 80% microns is normally achieved in 315 minutes of recirculation milling with 1.0 to 1.4 mm grinding media. By reducing the media diameter to 0.6 to 0.8 mm after minutes, the target grind is achieved in only 150 minutes.

charging and maintaining batch & continuous ball mills. smaller media more contacts. since particle size reduction takes place when the material being ground is sandwiched between the media, it is best to choose the smallest feasible grinding media combination as smaller media provide many more contacts than larger media.
ball mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. the rotation is usually between to revolutions per minute, depending upon the diameter of the mill. the larger the diameter, the slower the rotation.
small grinding media has a larger grinding surface area generally chosen to help make smaller ore smaller.
