Open Mixing Mill Technical Profile
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)
