200-400mm Two Roll Mill Machine With PLC Control System
Product Introduction
Two roll mixing machines are engineered to provide unmatched performance for masticating and kneading natural rubber, synthetic rubber, EVA, or PVC pellets with various chemical materials. This machine is primarily used for plasticizing, hot milling, and mixing of natural and synthetic rubber in rubber product manufacturing facilities.
Key Features
- Automatic feeding oil or grease lubrication system for easy maintenance and machine protection
- Brake and emergency stop devices to ensure personnel and equipment safety
- Frame, frame cap, and base are welded and treated by annealing for stress relieving
- Multiple roll nip adjustment methods: manual or electric operation
- Rolls manufactured from chilled cast alloy iron with hardness reaching 70HB
- Various roll constructions available: drilled roll, bored roll, grooved roll
- Customizable speed ratio design based on customer formulas and processing requirements
Intelligent Control Panel & PLC Control System
- Real-time data recording and export of kneading time, temperature (mixing chamber and front/rear rotors), ram pressure, current, torque, and recipe code
- Control system supports up to 20 mixing steps and 20 recipe storage spaces
- Remote process recipe import and data monitoring capability, communicating with MES via Ethernet communication interface
- Ethernet communication interface with 20% reserved control points and touch screen interface
