ABSTRACT:
An improved classifier cage for bowl mill type coal pulverizers which have been converted from stationary throats to rotating throats with reversed flow direction. The direction of the classifier vanes is reversed such that the rotational flow direction of coal/air from the rotating throat is generally maintained as it passes through the classifier cage into a classifier cone, rather than being reversed in "U-turn" fashion. A further improvement is made in the geometry of the classifier vanes to create a better downward and tangential redirection of the flow into the classifier cone.
