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
