Used Rubber Internal Mixer Supplier in China

Product Overview

We supply overhauled rubber internal mixers for tire compound mixing. This type of banbury mixer is widely used for mixing and remilling raw materials for large tires and general rubber compounds. It meets the process requirements of large tire factories and features low energy consumption and eco-friendly operation.

The internal mixer works in a closed mixing chamber to knead raw rubber, carbon black, oil and additives into consistent, homogeneous rubber compound. We have both tangential rotor and intermeshing rotor models in stock. The hydraulic ram, floating weight and discharge door maintain stable mixing pressure and consistent fill factor, so batches stay repeatable for tire production.

Advantages of Our Refurbished Tire Rubber Internal Mixer

• Fits large tire production processes Ideal for mixing and remilling tire raw materials. It handles tire tread, sidewall and common rubber formulations steadily to match production standards of large tire plants.
• Energy saving & low pollution Closed mixing design reduces dust leakage and material splashing. It cuts power consumption compared with old mixing equipment and keeps the workshop cleaner.
• Stable temperature control The mixing chamber is lined with wear-resistant alloy and equipped with circulating water cooling. It keeps compound temperature within the required range and avoids rubber scorch.
• Optional PLC control system Available PLC units record rotor speed, mixing time, ram pressure, discharge temperature and power curve. Operators can save tire compound recipes and switch formulations quickly.
• Flexible discharge for easy line integration Drop door and sliding door discharge options are available. The mixer can connect directly with screw conveyors or two roll mills to fit your existing tire compound line.

Auxiliary Equipment & Available Models

We also provide matching auxiliary units including stock blenders, dust collection systems and screw conveyors. We can build a complete second-hand mixing line if you upgrade or set up a tire compound workshop. Our inventory covers 110L and 160L used rubber internal mixers. These two sizes are popular choices for tire tread compound lines and expanding compounding capacity.

Every used mixer goes through full disassembly, overhaul, pressure testing and dynamic balancing before delivery. We can supply spare rotor seals, control cabinet repair service and English operation manuals as requested.

Typical Applications

Our refurbished banbury mixers are mainly used for:

• Large tire tread and sidewall compound mixing
• Remilling of general rubber compounds
• EPDM, NBR, reclaimed rubber and conveyor belt cover rubber
• Shoe sole compound and color masterbatch mixing
