Classifier Coal Specification

The coal classification employed in Canada is the ASTM ranking system that is based on the fixed carbon, and calorific value on the dry mineral matter free basis (dmmf). This system was adopted in 1938 and is a general guideline to classify different coal ranks. Table 1 lists coal rank classification under

    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
