Coal Grinding Ball Mill Design

May 16, 2007 The extension of the model to air-swept coal mills described by Austin et al. was used to simulate results from a 2.75 m diameter by 3.51 m air-swept ball mill and it also gave good agreement with actual plant data, for product size distribution and capacity in tph. The characteristic AKL breakage parameters determined in laboratory tests were
