how the air swept pulverizer works. the infeed material is fed into the air stream at the mill inlet 1 in a consistent metered fashion. the beater plates 2 impact and reduce the size of the largest particles and distribute the material around the periphery of the grinding zone where product is ground against the liner 3 by the hammers 4 which are mounted on the beater plates. the
a simulation model for an air-swept ball mill grinding coal. 85007-x get rights and content. abstract. the conventional model for grinding in tumbling ball mills was modified to allow for air-sweeping, for the case where all the material is carried out of the mill in the air stream. 266 a simulation model for an air-swept ball mill
in order to avoid excess sweeping of coal from the mill, only part of the primary air, directly proportional to the boiler load demand, is passed through the mill. furthermore, to ensure sufficient velocity of pulverized fuel to avoid settling in the pipes, an additional quantity of primary air is fed into a mixing box on the seven trust coal circuit.
air-swept coal mill is a kind of mechanical equipment that crushes and grinds coal briquette into pulverized coal, which is also important auxiliary equipment of pulverized coal furnace. when grinding coal in coal mill, it is mainly through crushing, shredding and pulverizing. air-swept coal mill is main equipment of cement plant, which is mainly used for drying and grinding pulverized coal.
