    Air from a centrifugal fan is made to flow from the cooler bottom through the layer of pellets. As in the vertical cooler, air is discharged into a dust-collecting system which removes the "fines" or particles which separate from the pellets. These are returned to the mill continuously for re-pelleting. 4.4 CrumblesPrimary and Secondary Air Measurement,Primary and Secondary Air Measurement Clearwater Clean Coal Conference June 6, 2010 Michael Higgins, P.E.
