The 15L internal mixer is a versatile piece of equipment designed for experimental mixing, kneading, and dispersing of chemical compounds including EVA, rubber, synthetic rubber, and hot melt adhesives. Test formulas prepared in this mixer can be seamlessly scaled to production processes. Its robust, wear-resistant construction ensures high efficiency, uniform material distribution, and reliable physical property improvements, making it ideal for laboratories, educational institutions, prototyping, and small-scale production applications.

The internal mixer operates with two rotors rotating at specific speed ratios within the mixing chamber. Material is fed through the inlet and drawn into the roller gap where it undergoes compression and shearing action. After passing through the gap, the material impacts the sharp edge of the "W" shaped mixing chamber, dividing into two streams that flow along the front and rear chamber walls before returning to the rotor top. This continuous cycle creates a closed mixing environment where materials experience intense shearing and mixing under controlled pressure and temperature conditions, ensuring complete dispersion and plasticization for optimal formula performance.

The mixing chamber features a "W" shaped configuration with an "M" shaped lower pressure cover, creating a fully enclosed mixing space. The prismatic spiral stirring blades eliminate dead angles, enabling comprehensive material shearing and dispersion to meet stringent physical property requirements. The hollow blade structure, constructed from high-carbon steel, undergoes quenching, tempering, and 72-hour deep nitriding heat treatment with hard chrome plating to maximize hardness, ensuring superior strength, wear resistance, corrosion resistance, and extended operational lifespan.

During normal operation, non-consumable components are guaranteed for one year. We provide comprehensive on-site installation guidance and ongoing technical support to ensure optimal performance and longevity of your equipment.
