· Coal mill modeling has been actively studied in recent years considering either simple models for process monitoring and fault detection or complex models for dynamic simulations. In Odgaard and Mataji (2006) a simple energy balance model is used for fault detection by estimating an unknown energy input.

inside the coal mill was solved by the realizable k ε turbulence model (RKE) with a detailed 3D classifier geometry meanwhile the discrete phase model was used to solve the coal particles flow. The steepest classifier blade angle of 40 o achieved the highest quality of classifiion where % of the coal particles are less than 75μm.
Improving Coal Pulverizer Performance and Reliability. ring is stationary) RingRoll (BowlMill) and BallRace Mills comprise the majority of coal pulverizers currently in service at power generating faciliti Figure 3 shows a cutaway of a RingRoll type coal pulverizer In this design the grinding rolls are stationary, while the ring (or bowl, as it is sometimes called) is rotated by a worm .
The first phase of this program should include a complete Mill inspection and accurate coal pipe testing which will establish baseline data. The information gained will include coal pipe balance, coal fineness, air/coal ratios, as well as the condition of the grinding components, mill throat, classifier, springs, and other components.
