  • Controlling The Explosion Risks Within Hammer Mills

    The risk of an explosion is low. Vertical Spindle Mills The vertical spindle mill is a medium speed pulverizer and maintains a considerable amount of fuel in the mill system when operating. Coal collects on the grinding table, in the classifier, in the pyrite collection sec- tion below the grinding table, and at the fan exit for exhauster systems.

    The present invention relates to a mill inert apparatus for a coal pulverizer in which an inert medium is introduced into a coal pulverizer for pulverizing coal to lower an oxygen concentration in the coal pulverizer, whereby the explosion of the pulverized coal is prevented, and it also relates to a method for preventing the explosion. 2.

    If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the in-rushing combustion air. Even in routine mill shutdowns, there is a danger that any residual coal left within the mill will oxidise, and may explode as the mill is restarted.
