Abstract: A cigarette manufacturing system includes a feed hopper for feeding cut tobacco at a preselected rate to a cigarette rod forming device which in turn feeds formed cigarette rods to a filter tip attaching device. A tobacco recovery system is provided which includes air conveying conduits in flow communication with the rod forming device, the filter tip attachment device and a tobacco dust and useable tobacco particle separator wherein particles of tobacco dust and useable tobacco particles recovered from the rod forming section of the cigarette maker and the filter tip attaching device are separated. The useable particles are re-fed back into the feed hopper. The tobacco dust is transferred to a tobacco dust recovery collector. The tobacco dust and useable tobacco particles separator include a centrifugal curved conduit in combination with a classifying chamber having a bottom outlet for removing useable tobacco and a top outlet for removing tobacco dust.
