Ball mills have been used for the preparation of coal–oil and conventional coal–water slurry fuels, also in large sizes up to a capacity of 50 tonnes of coal per hour (Austin et al., 1984). From: Advances in Clean Hydrocarbon Fuel Processing , 2011
Jun 15, 2018 Quantitative analyses of energy-size data indicate that grinding energy efficiency could be improved if raw coal in low ash content is chosen. Except for energy saving, less associated minerals in low ash coal can reduce the abrasion of grinding roller, increase the breakage rate, and decrease the emission of harmful air in combustion process.
Three methods were used to collect data from the same coal-ball peels and were compared for data comparability and for relative time efficiency. Although the data produced by the standardly used cm 2 grid method and by the newly devised random mm 2 method were of equivalent accuracy, the newly devised method is estimated to be much more time ...
