The coal then discharges through a variable-speed rotary feeder directly into the primary air pipe from where it is being blown into the kiln (see Fig. 2.2). Since these holding bins are usually relatively small, the mill, just as in the case of the direct-firing system, must be op erating at all times while the kiln is running.

Exshaw FM2 successfully uses this idea to make the mill sweep dust fine enough for finish cement. However the box is extremely large to accomplish this. As a rule of thumb for cement mills, the air velocity around the discharge trunnion and hood must be less than 4 m/s. In Exshaw's dropout box they strive for about 2 m/s.

The air-swept coal mill is suitable for a variety of coal types and pulverized coal requirements. It is capable of handling coals of different qualities, hardness, and humidity while adapting to different combustion equipment and process requirements.
Coal Moisture: The degree of drying, and therefore the required mill outlet temperature (from 65-80 0 C) will depend upon the type of coal ground. Some residual moisture in fine coal is recommended (Graph below) to minimize the potential of spontaneous ignition of fine coal, which will again vary for different coal types as below:
