Thermal Power Plants. These are normally mono chamber drum type structure, in which balls (of certain sizes) are fed and then the Drum / Mill is rotated at a critical speed such that balls stick on and reach top (theoretically) or almost top and fall with gravity on coal, there by crushing it. Tube Mills is lined with Liners so that.

Coal Pulverizer Maintenance Improves Boiler Combustion - POWER .

Dec 1, 2015 . We have found that targeting an A/F ratio around 1.8 lb of air per lb of fuel is best. For some pulverizer types, such as ball tube mills and high-speed attrition mills, often a 1.6 A/F ratio is optimum. Never have we observed good combustion conditions or good mill performance with A/F ratios of 2.5 or greater.
