Classification performance of model coal mill classifiers

Mar 01, 2020 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] ]

A Comparison of Three Types of Coal Pulverizers

A Comparison of Three Types of Coal Pulverizers

As the mill rotates, the balls cascade and pulverize the coal by impact and attrition. The pulverized coal is then conveyed by air to centrifugal classifiers. Properly sized pulverized coal exits the classifier into coal piping for transport to the furnace. Oversized pro- duct is, however, separated and returned to the mill for further grinding

he Flapper Valves on the MPS and MBF are designed to catch coal that has been rejected at the classifier level. The weight of the accumulated reject coal trips the Flapper Door and releases it for regrind. Air flow studies show that coal released from the Flapper Assembly falls into the air stream and can be carried back through the classifier to be rejected again, thus short circuiting the
