Coal fineness is defined as the d80 (80 % passing size). A quadratic model was developed to show the effect of parameters and their interaction with fineness of the product. Three different sizes (4, 1 and 0.65 mm) of Indian coal were used. The model equations for each fraction were developed and different sets of experiments were performed.

According to the base case analysis, if the mass flow rate from the mill is less than 10 kg/s, then the mill can become overloaded, and some of the coal will return for regrinding. After some time, because the coal is feeding into the pulverizer at a constant rate, the coal will accumulate in the mill, and the power consumption of the mill will ...
