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

Safety Operating Procedures

Pre-Startup Preparation:

Inspect all equipment components for normal condition
Verify electrical system functionality and instrument accuracy
Clear work area debris and ensure clean environment
Adjust roller spacing according to process requirements
Wear appropriate personal protective equipment

Startup Operation:

Ensure no personnel or obstacles near equipment before starting
Start main motor gradually and monitor for normal operation
Add rubber materials according to process specifications after stable operation

During Operation:

Maintain safe positioning - never place hands or body parts in roller gap
Add materials evenly and appropriately to avoid equipment overload
Continuously monitor rubber mixing and stop immediately if abnormalities occur
No maintenance or adjustments during equipment operation
Use emergency stop button immediately in case of emergencies

Shutdown Procedure:

Stop material addition after mixing completion
Discharge all rubber from rollers before stopping main motor
Shut down electrical system and clean equipment/workspace
Perform daily maintenance including lubrication and cleaning

Additional Safety Requirements:

Only trained personnel permitted to operate equipment
No unauthorized personnel near operating equipment
Regular equipment inspection and maintenance for optimal condition
Strict adherence to operating procedures and safety regulations
