16" Automatic Rubber Blending Open Mixing Mill
This industrial mixing mill features hard-faced rollers and a
high-horsepower motor for efficient rubber blending and
plasticizing operations.
Product Overview
The open mixing mill utilizes two hollow rollers rotating in
opposite directions to process rubber materials. The front roller
can be adjusted manually or electrically to control spacing, while
the rear roller remains fixed. This configuration creates intense
shear forces that effectively plasticize and mix rubber compounds.
Key Features
- Hard-faced rollers for extended durability
- High-horsepower motor for powerful operation
- Adjustable roller spacing for precise control
- Opposite-direction roller rotation with speed differential
- Simple structure for easy maintenance and operation
- Wide application across rubber and plastic industries
Working Principle
Raw rubber or compound is fed between two rollers rotating at
different speeds. The intense shear force generated in the gap
between rollers achieves effective plasticizing and mixing. Precise
control of temperature, rotational speed, and roller spacing
ensures optimal processing conditions.
Core Components
- Rollers: Direct contact components with precise surface treatment
- Transmission System: Provides stable and precise roller rotation
- Temperature Control: Maintains optimal processing temperature
- Control System: Advanced PLC for automated operation
Applications
Widely used in tire manufacturing, rubber product production, shoe
manufacturing, cable sheath production, plastic processing, and
floor fabric production lines.
