Application Scenario
As core equipment in the rubber industry, open mixing mills specialize in processing high-elasticity, high-viscosity compounds, including:
Conveyor belt skim compounds
Precision pre-forming for seals/gaskets
Reinforcement layers for hydraulic hoses
Cable shielding compounds
High-temp vulcanizates for vibration dampers
Product Function
Mastication: Reduces raw rubber molecular weight, improves plasticity
Blending: Uniform dispersion of carbon black/additives (≥98% dispersion rate)
Thermal Mixing: Temperature control range 50-180°C (±2℃)
Sheet-Forming: Produces standard sheets (2-15mm thickness)
Key Features
| Feature | Technical Implementation | User Value |
|---|---|---|
| Custom Design | Modular configuration of roller size/speed ratio/power | Adapts to specialty compounds (fluoroelastomer/silicone) |
| Safety Device | Hydraulic overload protection + Mechanical shear-pin system | Shear pin fractures in 0.1s during overload, protecting rollers (↓60% repair costs) |
| Wear-Resistant Rollers | Surface hardening treatment (HRC 65±2) | Service life ≥30,000 hours |
| Smart Control | PLC + HMI (≥50 recipe storage) | Process consistency (CPK≥1.67) |
| Fast Material Change | Motorized nip adjustment (±0.1mm precision) | Material change time ≤15 minutes |
