Coal Pulverizer Explosions - Babcock Power
With bituminous coals the vertical spindle pulverizers show a higher explosion frequency while the ball and attrition pulverizers have equivalent lower frequencies. Also, subbituminous grinding vertical spindle pulverizers have about twice the explosion frequency of bituminous grinding vertical spindle pulverizers.

A Comparison of Three Types of Coal Pulverizers
As the mill rotates, the balls cascade and pulverize the coal by impact and attrition. The pulverized coal is then conveyed by air to centrifugal classifiers. Properly sized pulverized coal exits the classifier into coal piping for transport to the furnace. Oversized pro- duct is, however, separated and returned to the mill for further grinding.
