Coal fineness above 300 μm was categorized as coarse, while coal fineness below 75 μm was categorized as fine coal powder. All pulverizers were able to classify more than 50% of fine coal. On the other side, pulverizer namely "B" had the highest coal fineness result of 77.78%, and Pulverizer D had the lowest coal fineness result of 51.96%.
