The fineness of the milling product and the capacity of the pulverizer are strictly connected. With increased fineness grows the overall circulation rate of coal in the mill, coal retention time and the flow resistance. As a result, the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system deteriorates.

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.

With the increase of cement mill specifications and the requirement of energy saving, high yield, and high quality of cement grinding plant, the closed-circuit grinding is an inevitable trend of cement grinding unit.The essential equipment of a closed-circuit grinding system is a cement classifier, also known as a cement separator.The function of the cement …

Once normal coal flow is applied to the mill, a full mill test should be conducted. This should include isokinetic coal sampling and dirty airflow measurements through each fuel line to determine air fuel balance and coal fineness. Primary airflow "Hot-K" calibrations of the primary airflow measuring element should also be conducted.
