Higher pulverized coal fineness increases the recirculation in the mill and the output reduces. The inlet size of the coal also affects the mill output directly. Mill air flow variations result in changes in mill outlet temperature and fineness as well as capacity. Ball tube mill. Ball tube mills are either pressurized or suction type.

deteriorate coal fineness since the Atrita mill is an attrition type mill. Diluting the particle concentration will result in less particletoparticle interaction and less size reduction due to dilution. For A/C ratios from to, the expected moisture to be evaporated will be between 10% and 14%,
