Named after English scientist and engineer Fernley Banbury, the Banbury mixer has been used in industries including food, pharmaceutical, plastic and chemicals, but its most widespread use is with rubber. In fact Banbury was awarded the Charles Goodyear medal. In the rubber and tyre industry in particular the Banbury mixer uses a twin rotor churning action to blend different natural and man-made rubbers with additives such as oil and carbon black. A powerful and geared drive is required. Heat is often produced and fumes rise on the thermal currents out of the mixer. A close fitting canopy hood can be employed and short duct work to a suitable scrubber. Because of the sticky nature of the constituents the duct work length should be minimized and kept straight where possible.The ideal collector is the AAF RotoClone type N wet scrubber
