Product Details
Product Positioning
In compound rubber lines or any process involving thermal milling, the post-treatment cooling machine is a critical unit following heat treatment equipment like dry mixers or internal mixers. It rapidly and uniformly cools activated high-temperature rubber to a safe level, preventing accidental early vulcanization (scorch) and creating ideal conditions for subsequent baling, storage, or further processing.
The primary role is to provide forced, rapid cooling for compound and mixed rubber immediately after thermal processes like dry mixing, internal mixing, or calendering. High-temperature rubber is placed on a slow-moving stainless steel mesh belt conveyor and enters a sealed cooling tunnel. A group of axial fans at the top blows powerful cold air downward, while side exhaust fans quickly remove hot air that has absorbed heat from the rubber, forming an efficient, circulating forced air cooling system.
Product Advantages
Rapid Forced Air Cooling: Uses a 'powerful blow + powerful exhaust' circulation system with high air convection speed and heat exchange efficiency, cooling rubber to near room temperature in a very short time.
Premium & Durable Materials: The conveyor system uses high-strength chains and stainless steel mesh belts, which withstand high temperatures and offer excellent corrosion resistance.
Uniform Cooling & Quality Assurance: The mesh belt ensures the bottom of the rubber also has full contact with cold air, achieving three-dimensional cooling and avoiding internal-external temperature differences.
Continuous Operation & High Efficiency: The continuous transport feature allows for seamless integration with upstream equipment, automating the entire flow from heat treatment to cooling.
Applicable Product Types
Compound Rubber, Mixed Rubber, Reclaimed Rubber (after thermal milling), Natural Rubber (NR) (after specific thermal processing).
Application Scenarios
Compound Rubber Production Lines: Positioned after the dry mixer for rubber cooling.
Mixed Rubber Workshops: Used for cooling sheets after internal or open milling.
