A study of ultrafine grinding of lowrank coals in a fluidenergy mill was undertaken. The overall project objectives were to (1) measure selected properties of ultrafinepulverized, lowrank coal as a function of coal source and product moisture, and (2) determine the power requirements for a fluidenergy mill to produce /minus/10 micron sized particles as a function of coal source and ...
This paper presents a coal mill model that considers the effect of coal moisture on its accuracy. This mathematical model is derived through the analysis of mass flow, heat exchange, and energy transferring balances in which all heat input into or output from the coal mill are calculated quantitatively to reduce the number of unknown parameters that need to be identified.
