Exhaust from the dryer chamber and the vibrating fluid bed is drawn through the baghouse and the sock filters remove the FINES. The filters are back-pulsed with air from above the top plate of the baghouse. FINES fall to the base of the baghouse where there is a fluidised bed with an air inlet for fluidising. The FINES fall through the outlet at the base to a rotary valve and into the FINES return line where they are blown (roots blower at upstream) either back top the top of the drier chamber or to either the upstream or downstream end of the fluidised bed.
