Product Description
Low Price Rubber Open Mill / Rubber Mixing Mill Customized To Different Sizes
Our rubber mixing mill with 450mm roller diameter is a versatile and reliable rubber processing equipment designed for various industrial applications.
Machine Structure & Components
Roller: Core component with 450mm diameter working surface, featuring hollow structure for heating/cooling operations and specially treated high-hardness, wear-resistant surface.
Frame: Welded steel structure providing high strength and rigidity to support and fix all components, ensuring overall stability.
Transmission System: Efficient power transfer from motor to rollers using gear transmission for smooth operation and high efficiency.
Gap Adjustment: Worm gear or hydraulic adjustment system for precise control of roller spacing to meet different processing requirements.
Safety Features: Emergency brake system with quick-stop functionality and emergency stop button for operator protection.
Temperature Control: Electric or steam heating with water cooling capability to maintain optimal processing temperatures.
Working Principle
The mixing mill operates with two counter-rotating rollers at different linear speeds. Rubber material is fed into the roller gap where it undergoes strong shearing and extrusion forces. This mechanical action breaks molecular chains and distributes components evenly, achieving thorough plasticization and mixing through repeated processing cycles.
Performance Specifications
- Roller Linear Speed: Front roller 18-25m/min (varies by manufacturer)
- Speed Ratio: Front to rear roller ratio approximately 1:1.27
- Batch Capacity: 25-50kg per cycle (depending on rubber type and formula)
- Motor Power: 45-75kW driving motor for optimal working capacity
Applications
- Rubber plasticization to reduce molecular weight and increase processability
- Rubber mixing for uniform dispersion of compounding agents (carbon black, sulfur, accelerators)
- Hot refining to improve rubber fluidity and temperature uniformity
- Rubber sheeting for producing consistent thickness rubber sheets
Advantages & Limitations
Key Benefits:
- Simple operation with minimal training requirements
- Strong applicability for various rubber types and formulas
- Open structure allows direct process observation and adjustment
Considerations:
- Manual material handling requires operator effort
- Working environment may include dust and exhaust emissions
- Production efficiency lower compared to internal mixers
