15L Water Cooled Rubber Lab Kneader For Metal Powder Mixing
Lab Kneader featuring tungsten carbide coated pressure hammer mixing chamber and blades for effective metal powder mixing
This mixer features components that contact materials—including the mixing chamber, side plate, pressure hammer, and mixing blade shaft—coated with tungsten carbide ultra-wear-resistant, pollution-free coating. It is designed for stirring, dispersing, and mixing metal powders with binders and other formulations at controlled temperatures. Once the material forms a mud mass, it is discharged for subsequent processing. Ideal for small-batch production, prototyping, laboratories, and educational applications.

Two rotors in the mixing chamber rotate at specific speed ratios, capturing material from the feeding port and directing it through the roller gap. Here, the material undergoes squeezing and shearing. After passing the gap, it strikes the sharp edge of the "W"-shaped mixing chamber, splitting into two streams that flow along the front and rear chamber walls before returning to the rotor top. Within the sealed chamber, materials are subjected to intense shearing and mixing under controlled pressure and temperature, ensuring optimal dispersion, plasticization, and formula performance.
The "W"-shaped mixing chamber, combined with an "M"-shaped lower pressure cover, creates a fully enclosed mixing environment. The prismatic spiral stirring blade eliminates dead angles, enabling precise shearing and dispersion to meet physical property requirements. Constructed from high-quality, high-carbon steel, the hollow stirring blade and other material-contact components undergo tempering, deep nitriding heat treatment (72 hours in vacuum), and tungsten carbide coating with smooth surface finishing. This ensures wear resistance, corrosion resistance, non-stick properties, and extended service life.

The anti-leakage powder mechanism from Changfeng relies on a mechanical shaft seal that is tightened in place, featuring self-lubricating rings to maintain steady compression and a reliable seal during use. As a result, component wear is reduced and leakage-related noise is kept to a minimum. A pass-through heating system supplies faster and more evenly distributed heat, achieving around 50% higher efficiency compared with standard heating plates, and a PLC-based program control option is available on request. In the mixing chamber, the intricate tube-belt design supports outstanding heat exchange and precise temperature management, while the water-cooled rotors stop material from clinging, boost temperature accuracy, and encourage even mixing.
Non-consumable parts are guaranteed for one year under normal use. We provide on-site installation guidance and long-term technical support. Note: Electrical components and motors are sourced from Taiwan and international brands.
