During operation, the two rotors of a Banbury mixer rotate in opposite directions, clamping and drawing the material into the roll gap. The material is subjected to compression and shearing forces from the rotors. This powerful action causes continuous deformation of the material, achieving efficient mixing. As mentioned in "Banbury Mixer (machinery used for rubber plastic refining and mixing) - Encyclopedia," the shearing action on the material during mixing in a Banbury mixer is much greater than that of an open mill, resulting in higher rubber processing temperatures and significantly higher mixing efficiency compared to an open mill. The two rotors rotate in opposite directions, shearing and compressing the material to achieve efficient mixing.

The material undergoes complex movements within the Banbury mixer to achieve uniform mixing and plasticization. The material undergoes a complex movement process within the Banbury mixer to achieve uniform mixing and plasticization. On the one hand, the material is subjected to compression, shearing, and stirring between the elliptical rotors and the mixing chamber walls; the kneading and tearing action brought about by the counter-rotation of the two rotors; and the axial kneading and material turnover action between the rotors. As described in "Exercises and Answers for Plastic Molding Machinery (2)_word document online reading and download - Worry-free Documents," the Banbury mixer utilizes the pressure from the upper ram, the special shape of the rotors and the mixing chamber walls to create special movement changes, and multiple actions such as axial force, heating, and plasticization exerted by the rotors to promote uniform mixing and plasticization of the material. On the other hand, the rubber in the Banbury mixer flows in different regions, enabling material exchange and mixing. For example, in the transitional area connecting the two halves of the mixing chamber, the rubber is compressed by the pressure of the upper ram on the one hand, and on the other hand, under the action of two rotors rotating at a certain speed ratio, it moves across this connecting transition area under the action of the left (right) rotor ridge, depending on the corresponding position between the two rotors, and enters behind the right (left) rotor, achieving the flow and exchange of rubber in the two halves of the mixing chamber. At the same time, the reasonable selection of the filling factor plays an important role in the exchange of rubber in the two halves of the mixing chamber.
