A new model-based approach for power plant Tube-ball
网页2014年4月1日The working principle of the coal mill is illustrated in Fig. 1 [25].In normal practice, there are two coal feeders for each mill. Once the raw coal flows into the mill barrel with hot primary air, the iron balls inside the rotating barrel will continuously crash the coal until it is fine enough to be blown out the mill to the furnace.
