Hammer mills are often engineered to be strong enough to contain a dust explosion, but sparks or smoldering particles may spread from the mill to other more vulnerable equipment. Associated cyclone/dust collector units are not as strongly constructed, and should be equipped with explosion relief and a rotary valve at the discharge.
PETER FIELD, in Dust Explosions, 1982. 2.1 AN HISTORICAL VIEW OF DUST EXPLOSIONS. Dust explosions have probably been with us since the time that man developed the windmill for grinding grain. In fact, the first known report of a dust explosion dates back to the eighteenth century; Count Morrozo  gives an account of a violent explosion of flour dust in a Turin mill in 1785.
