To measure grindability, Bond developed 'Bond's Work Index' (BWI), a 'test mill' and a testing procedure for WI. With the help of this we can work out power required to grind a material from a given feed size to a product of given fineness.

which is due to the complex mill ducting, is required. The number of techniques which can be utilized to measure coal flow is limited, gener­ ally expensive and does not readily adapt to fully operational industrial flows. Typically, coal flow and fineness have been measured only at steady-state conditions and only intermittently using extractive

The mill wear and the power consumption are increased if the 70% value is exceeded. Values lower ...

Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature. However, the major benefit of using ball mills is the product fineness they can deliver.

Highlights. • The effect of a coal mill classifier speed was measured online in a 660MWe plant. • The coal particle fineness and the coal flow distribution were monitored. • The amount of particles <75 μm varied between 66 and 74%. • The maximum coal flow deviation was reduced from 14% to 9%.

7. Coal Size Coal grain size is limited in the range of fine-grained (coal or dust pulverized coal) and coarse grains (mass of coal). The most delicate to the maximum size of 3 millimeters, while the coarse grain sizes up to 50 mm. 8. Grinding Hardgrove Index (HGI) Devastating performance or mill is designed, in particular, the values of HGI.

Almost all of these constantly change, which makes it difficult to maintain constant fuel fineness and to monitor the mill maintenance condition. The ECT system can be configured to measure the fuel fineness on-line. To obtain the relevant signals two sensors are mounted in a coal pipe right after a pipe bend (Figure 7).

Instead of maximizing coal fineness improvements only, the dynamic classifiers can be used to increase mill capacity while improving the pre-retrofit fineness level somewhat or the capacity can be maximized by allowing the fineness to drop to lower levels. The enhanced
