Grinding is a random process and is subjected to the laws of probability. Grinding steps: i. Primary (Coarse) grinding (generally a rod mill is used)(Feed size as large as 50 mm, product size as fine as 300 microns)(1000 microns = 1 mm) ii. Secondary (Fine) grinding (generally a ball mill is used)(Feed size as large as mm,
