1. CLASSIFICATION OF INSTRUMENTS IN POWER PLANT

In coal-fired power stations, the raw feed coal from the coal storage area is first crushed into small pieces and then conveyed to the coal feed hoppers at the boilers. The coal is next pulverized into a very fine powder. The pulverizers may be ball mills, rotating drum grinders, or other types of grinders.

New method to measure grinder fines percentage? - Page 4

The Kinu M47 adjusts via a fine threaded (0.5mm pitch) machine screw so each full rotation (+100 setting) is a distance of 500µm vertical travel. Since it is a conical burr the change in burr separation is some fraction of that distance, a function of the burr angle. The zero on my grinder is not the point where the burrs touch.
