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 0.5 mm,
Raw material and slag grinding In the beginning the RP was used only in combined mode with either a ball mill or even with impact hammer mills. The first raw material grinding circuit in finish mode based on RPs was installed in the 1990s, and since then, this configuration has become the state-of-the-art technology for raw material grinding.

Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.
In modern rice mills, many adjustments (e.g. rubber roll clearance, separator bed inclination, feed rates) are automated for maximum efficiency and ease of operation. The whitener-polishers are provided with gauges that sense the current load on the motor drives which gives an indication of the operating pressure on the grain. This
