120mm Rubber Lab Two Roll Mixing Mill With Electrical Heating
This precision-engineered two roll mixing mill delivers exceptional performance for masticating and kneading natural rubber, synthetic rubber, EVA, or PVC pellets with various chemical materials. Designed primarily for plasticizing, hot milling, and mixing of natural and synthetic rubber in rubber product manufacturing facilities.
Applications
This rubber plastic open two roll mixing mill is extensively utilized in the rubber and plastics industry for polymer mixing applications including PVC, color master batch production, and carbon powder processing. The system comprises rolls, bearings, gap adjusting mechanisms, electric control systems, and comprehensive safety features.
Key Features
- Multiple roll construction options: drilled roll, bored roll, grooved roll
- Customizable speed ratios tailored to specific formulas and processing requirements
- Anneal-treated frame, frame cap, and base for stress relief and durability
- Chilled cast alloy iron rolls with hardness reaching 70HB
- Integrated brake and emergency stop systems for personnel and equipment safety
- Automatic oil or grease lubrication for easy maintenance and machine protection
- Ergonomically designed control system ensuring operator safety
- Flexible roll nip adjustment: manual or electric operation
Intelligent Control System
Advanced PLC control system with real-time data recording and export capabilities for kneading time, temperature (mixing chamber and rotors), ram pressure, current, torque, and recipe codes. The system supports up to 20 mixing steps and 20 recipe storage spaces, with remote process recipe import and data monitoring via Ethernet communication interface compatible with MES systems.
