A minimum airtocoal weight ratio of :1 is desired at full load. The ratio could be higher at lower loads (more air per pound of coal). Failure to provide adequate airflow through the mill can result in spillage of coal. The exhauster discharge pressure is an indicator of flow and velocity through the coal piping.
