B&W Roll Wheel™ Pulverizer Modifications Improve

The DSVS® rotating classifier provides a means to increase coal fineness and/or throughput (Figure 2). This mill retrofit goes well beyond the improvements achievable with stationary classifier retrofits, especially when 80+%/200 fineness is required. Rotating classifier pressure drop is lower than that of stationary classifiers.
