Nov 06, 2017  Colorants. Mesh size can make a big difference with colorants. For example, when making a blue celadon, if you use 100-mesh black iron oxide (an old school way of mixing blue celadon with a coarse grind) you might get speckling. This can be corrected by ball milling the colorant in a small amount of the glaze for several hours then adding it to the whole batch.

Rod mills, how they function - Mine Engineer.Com

The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).
