Different layouts in the Banbury – type mixers

1. Mixer with rolling mill directly below discharge. The trap door opens to dump the



“mix” directly into the mill.


2. Mixer with conveyer to rolling mill. The “mix” is taken to the rolling mill on a


conveyer.






3. Mixer in combination with an extruder. The “mix” is dumped directly into an


extruder.






The important specifications of a mixer include the mixing chamber volume (in


liters), batch size (in kg.), maximum rotor speed (in rpm) and installed power/rpm


(kW/rpm)
