on 70% of the coal passing through a 200 mesh screen. Mills are capable of grinding harder coal with higher percentage moisture content and can reduce the product fineness in excess of 90% passing a 200 mesh screen at a reduced output capacity. The feed size of the coal to the mill should be precrushed to 1 top size. Available capacity size
Improved mill availability Longer acceptable coal fineness results from longer lasting grinding surface profile Reduced frequency of grinding roll to grinding segment gap adjustments No spauling which can occur with other materials Maintains grinding surface
