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
