The coal is pulverized in coal mill or pulveriser to fineness such that 70-80% passes through a 200 mesh sieve. The factors that affect the operation of the mill or reduce the mill output are: • Grindability of coal: Harder coal (i.e. coal having lower hard-grove index (H.G.I.)) • reduces mill output and vice versa.

Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will
