COAL BASED THERMAL POWER PLANTS COAL MILLS FOR nbsp 0183 32 This mill uses central horizontal shaft which has a number of arms and a beater of different design is attached to these arms to beat the coal to be pulverized High speed impact mills are mainly used in pulverizing lignite Today all boiler designers opt to use ball or vertical spindle mill for coal other than lignite
Mill operating parameters determine the mill operating window which provides the limits in which a mill best operates and outside of which constraints are experienced The mill operating window is plotted using the mill operating parameters such as drying limit erosion limit milling capacity limit tampering limit flame stability limit and pulverised coal transport Fig 1 shows a typical
