Manganese mill dust explosion - ScienceDirect

The explosion potential of coal dust is well appreciated and has been studied at length by the US Bureau of Mines. The data indicate that manganese dust is explo- sible at a low dust cloud concentration, at only about 30% that of coal dust on a particle volume basis. (The specific gravities of manganese and coal dust are 7.2 and 1.35, respectively.) The ease of ignition of man- ganese as a ...
