2.1: Grinding Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used.

For ball mills, it is more efficient to reduce the size of large particles prior to the mill, using physical means such as a hammer crusher, pre-grinder, or a roll press. Fine clinker is less of an issue in a ball mill, since the material simply passes through to the second chamber for fine grinding, although this can reduce the impact of the ...

The grit size of the abrasive depends on the dimension of the balls and process requirements. In general, smaller balls require fi ner grit and harder grade, larger diameter balls require coarser grit and softer grade. Grit size ranges from 120 to 320. INSPECTION Every ball is checked and any ball with the slightest defect is removed.
