Description
The Buss Ko-Kneader Extruder is a type of extrusion equipment used in the plastics and rubber industries for compounding, mixing, and processing of high-viscosity materials. It was developed by the Swiss company Buss AG and is known for its unique kneading disc design, which provides excellent mixing performance, efficient heat transfer, and low shear stress on the material being processed.
The Ko-Kneader Extruder operates with a reciprocating screw that moves back and forth in a specially designed barrel, while the kneading discs rotate at a different speed. This process generates high shear forces and intense mixing action, resulting in a homogenous blend of materials.
The Buss Ko-Kneader Extruder can be used for a wide range of applications, including compounding of thermoplastic elastomers (TPE), hot-melt adhesives, masterbatches, polymer alloys, and high-filled systems. Its advanced technology and performance have made it a popular choice for various industries, including automotive, construction, packaging, and medical products.
