Cast iron grinding balls are used in large quantities in grinding mills for crushing coal, ores, cement, and many other objects. Grinding balls need to have good resistance to cyclic impact loads in addition to high wear properties as they suffer repeated collisions with other balls, hard liner plates as well as the objects for crushing.

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.

A type of C Si :Mn nodular cast iron, used as grinding ball material, was studied. With 2.5-3.3 wt% C, 3.0–3.5 wt% Si and 2.0–2.5 wt% Mn, this type of nodular cast iron can be melted by cupola. Simple process, low cost, and high wear resistance make it more competitive as a ball material than other nodular cast irons.
