    The grinding capacity of the coal mill is gradually reduced at 10 s, and the raw coal stored in the mill is gradually increased (Fig 7(e)) Since the conversion efficiency of raw coal to coal powder is reduced, the coal powder stored in the mill is decreased in the initial stage of simulation (Fig 7(f))Energy consumption and dissipation are discussed, leading into a thermal model for grinding The analysis developed over many years applies to shallowcut conventional grinding processes and also to deep grinding processes Energy analysis provides insights into the grinding process and suggests avenues for process improvementsEnergy and temperature analysis in grinding
