Dust explosions are very similar to gas explosions. Depending on the containment configuration, if any, a pressure rise can take place. An ignition source (BS EN 1127) typically causes a primary explosion, which provides the energy and promotes airborne dusts, resulting in a secondary explosion, which is generally much more serious than the primary.

Reason #2：The supplement of steel balls is insufficient. Due to the longterm operation of ball mill, the steel balls will wear violently, the diameter will be reduced, and the impact force will be correspondingly weakened. When the steel balls in the ball mill are not replenished in time, the processing capacity of the ball mill will be reduced.
