The General Function of Ball Mills. A ball mill is a grinder used for grinding and blending materials for mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. Appearance. Ball mills have various designs and functions, ranging from laboratory-scale versions to large industrial models.
One obvious reason is that impact energies in laboratory mills are negligible compared to those in industrial mills. For example, Dodd et al. (1985) have estimated that an increase in ball kinetic energy from 1.4 J for a 0.025 m ball in a 0.20 m ball mill to 350 J for a 0.127 m ball in an 8.5 m ball mill.
Like the second one, the ore is ground in a mill and sent by way of a pump box to a classifier. Now however there has been a second mill added. The rock that requires further grinding is sent to this mill where it is reground. Once the ore has gone through the mill, it is sent by way of the pump back for reclassification.
