Rubber Internal Mixer Series
Application
This machine is mainly used for the mixing and final refining of rubber compounds, ensuring uniform dispersion and stable product quality.
Structural Features
1. Various rotor designs are available to meet different mixing and refining process requirements. Custom configurations can be selected based on customer needs.
2. The rotor, mixing chamber, discharge door, and ram are all equipped with a circulating water cooling system, featuring a large heat exchange area. An optional temperature control system ensures stable compound quality.
3. The rotor surface, inner chamber walls, discharge door, ram, and other contact parts are overlay-welded with wear-resistant alloy and chrome-plated, significantly improving wear resistance and service life.
4. The rotor end sealing system adopts oil-lubricated sealing, with adjustable pressure and reliable sealing performance.
5. The top ram is hydraulically driven, enabling constant pressure control during mixing.
6. The bottom discharge door is driven by rack-and-pinion combined with hydraulic cylinders, ensuring smooth operation, strong locking force, excellent self-locking performance, and tight sealing.
7. The transmission system features smooth operation, low noise, and long service life. Speed and structure can be customized according to different process requirements.
8. The control system adopts PLC control, supporting both manual and automatic modes. It offers easy operation, strong anti-interference capability, and reliable signal detection and feedback functions.
The system can be integrated with upstream equipment to achieve fully automatic operation, reducing labor intensity and improving production efficiency.
Key Advantages
1. Increased rotor speed significantly shortens mixing time under the same process conditions, reduces energy consumption per unit, improves production efficiency, and enhances compound quality.
2. Equipped with high-efficiency variable frequency motors, ensuring proper power matching, energy saving, and reduced electricity consumption. Compared with DC motors, it greatly lowers maintenance costs.
3. The top ram adopts dual hydraulic cylinder drive, providing more stable operation and precise constant pressure control. The hydraulic station is controlled by a servo motor, ensuring higher positioning accuracy.
4. The discharge door is hydraulically driven with a buffering design, allowing smooth opening/closing and stable operation with minimal vibration.
5. The reducer adopts a high-strength hardened gear reducer, featuring low noise and high precision, specially designed for intensive mixing conditions with an enhanced safety factor.
6. We provide complete turnkey solutions for rubber mixing centers, including upstream feeding systems, internal mixers, open mills, rubber sheet cooling lines, and environmental dust removal systems — offering true one-stop service.
