biomass optimised mill must produce particles around 1 mm, while a coal optimised mill should produce particles around 70 µm. This is difficult to achieve at the same time in a cofiring situation, where coal and biomass are milled together. This will likely result in a significant over milling of the biomass fraction, which will have a negative affect on the mill capacity. Required ...
