Get priceThe REFLUX classifier incorporates the new ''laminar high shear rate'' mechanism: the latest in fine particle gravity based separation technology. This, along with advancements in channel spacing and width mean that REFLUX classifiers are more efficient and more compact than competing fine coal and mineral processing equipment.
Get pricehe 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 ...
