CFD modeling of MPS coal mill with moisture evaporation

 — While the coal is being moved upward, gravity separation occurs due to decreased velocity with increased area of the mill. Final separation of coal, termed as secondary separation, occurs in a classifier by centrifugal force induced by tilted vanes of the classifier. Reject coal from the classifier falls into silos with flapper gate valves.

 — The modern coal mill classifier, however, often has an impeller mounted close to the exit of the mill chamber. The impeller is a cage with a set of blades installed around its outer ring. It introduces a secondary classification by the collision effect in addition to the primary classification by centrifugal force [[11], [12], [13]].

Bowl Mill Coal Pulverizer

 — 2. The hot air is used for transportation of the recirculating coal within the mill and also for transporting the coal from the pulverizer to the furnace. As the coal is continuously reduced in size, the smaller/lighter particles are swept from the bowl by the hot air. Hot air (and cool tempering air) is provided by the primary air fans.
