The size of 30 mm was optimum for raw materials of −0.45 + 0.15 mm and −0.15 mm. The optimal ball size distribution was 12 mm (40%), 20 mm (40%), 32 mm (10%), and 40 mm (10%) for dry fine-grinding of calcite ore. Finer ball loads were unable to break coarser particles nipped in the feed.

The equation for Rittinger's Law can be written as: E = K R f c (1/L 2 – 1/L 1) Where: E=Energy, K R =Rittinger's Constant, f c =crushing strength of the material, L 1 =initial length, and L 2 =reduced length. Kick's Law states that the energy is proportional to the size reduction ratio. The equation for Kick's Law can be written as:
A mill is a device, often a structure, machine or kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or …
