Used Banbury mixers for sale: heavy-duty compounders for rubber, plastics and high-viscosity materials

Used Banbury mixers are powerful internal batch mixers designed for high-viscosity materials that require intensive kneading, shearing and dispersion. These mixers are a mainstay in rubber production, plastics blending and specialty chemical compounding. With more than 47 years of industry leadership, IPP supplies used, surplus and secondhand Banbury mixers from 20 global plant sites and maintains a deep inventory of 15,000+ systems ready for immediate deployment.=

IPP stocks Banbury-type mixers and compatible internal mixers from OEMs including Farrel, Kobelco, Werner & Pfleiderer, and HF Mixing Group.

Applications and industries

• In rubber processing, for blending natural and synthetic rubber with carbon black, fillers and additives
• In plastics compounding, for color masterbatches, PVC blends, and thermoplastic elastomers
• In chemical manufacturing, for resin kneading and high-torque mixing of viscous polymers
• In automotive and tire production, for preparing dense rubber compounds used in treads, seals and bushings

Types of materials processed

• Natural rubber, synthetic rubber, and elastomers
• PVC, polyethylene, and engineering plastics
• High-viscosity adhesives, sealants and molding compounds
• Reinforced polymers and filler-laden mixtures

Common materials of construction

Banbury mixers are built for strength, wear resistance and long operational life:

• Carbon steel frames and housings for rigidity under torque
• Chromed or hard-faced rotors and mixing chambers for abrasion resistance
• Jacketed mixer chambers for steam or water cooling
• Split drop doors and hydraulic drives for rapid discharge and easy cleaning

Key features of Banbury mixers

• Twin-rotor design for simultaneous shearing and folding
• Pneumatic or hydraulic ram for top pressure application
• Variable-speed motor drives for process flexibility
• Jacketed chambers to control mixing temperature
• High-torque mixing for materials that resist flow
