A redundancy between ball mill utilization and ball mill power is observed, confirmed by similar statistics of power and utilization in Table 1, which explains similar correlation in Table 2. Relationships between TPH and particle sizes of the ore that result from Bond's law (Equation (1)) are shown in Equations (7) and (8).

Maintenance Of Ball Mill Use In Thermal Power Plant. Use Of Ball Mill In Thermal Power Plant Dec 13 2011 coal based thermal power plants normally the ball mill designers use three types of balls with three different diameters these balls reduce in size as the mills operate and so the highest size ball is normally used for recharging

This suggests that charging GIS mills with small media may not be practicable in plant operation. Millpebs. Millpebs have been used as grinding media to achieve fine grinding in ball mills. These are 5- to 12-mm spherical or oblong cast steel pellets, charged into ball mills as a replacement of, or in addition to, balls.

Ball mill, providing grinded coal for the boiler, is an important role in a thermal power plant and consumes 15 ~ 25 % of the whole energy consumption of the thermal power plant. Therefore, ensuring the efficiency of ball mill operation is of consequence for the sake of energy.
