Coal Blending - an overview | ScienceDirect Topics
For blending of multiple coals, blending calculations are best performed using the simple tabular format shown in Table 17.1. The total ash content of the mix is calculated by dividing the total tons of ash by the total tons of coal (i.e., 2400/25 000 = 0.096 = 9.6%). Simple weighted averages can be used to calculate a variety of common assays,
