High Moisture Coal Mill - ledermann-bruengger.ch

Jun 07, 2018 Higher moisture content requires temperature extremes inside the mill. High moisture, high volatile matter and highly reactive coals are prone to self heating and can spontaneously ignite due to rewetting. Rehydration is exothermic and dried coal that is stagnate anywhere in the coal mill can begin to smolder and burn.
