1. Introduction. Duplex inlet and outlet ball mills are widely used in 200300 MW coalfired generating units. This pulverizing system is easily adaptable to multiple coal type and is simple to operate, thus it is suitable for pulverizing coal with low grindability, high abrasiveness and required degree of fineness.

A Comparison of Three Types of Coal Pulverizers. Ball Tube Mill The Ball Tube Mill (BTM) is a cylindrical lowspeed grinding mill. It consists of a steel barrel, lined with cast abrasionresistant liners and partially filled with hardened steel balls. Coal and preheated primary air enter one or both ends of the mill from a crusher/dryer or feeder.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

The kwhr/ton requirement in pulverization which has no correction for differences in fineness produced, ranged from to for the ball mill and from to kwhr/ton for the hammermill. Pulverization of the lignite from the Indianhead mine in the hammermill is again the exception; this required kwhr/ton.
