Banbury mixer
The internal rubber mixer, internal mixer for short, is mainly used for rubber plasticating and mixing. The internal mixer, equipped with a pair of rotors which perform relative rotation with the specific shape, is a kind of machine for intermittently plastic and mixing the polymer materials under the enclosed condition with adjustable temperature and pressure. The mixer is mainly composed of the chamber, rotors, rotor sealing devices, charging & pressing devices, discharging devices, gearing, base, etc.
