Product Description

Custom 3L Metal Powder Kneader Machine

Product Overview

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.

Product Advantages

Advanced powder leak-proof design for easy replacement and removal
Enhanced heating and cooling system with faster warming and superior cooling performance
Utility model patents for ceramic and metal applications; interior contact surfaces coated with ultra-wear-resistant alloy to significantly extend service life

Operating Principle

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.

Mixing System

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.

Technical Advantages

Changfeng's anti-leakage powder device uses mechanical shaft seal tightening with self-lubricating seal rings, maintaining compression and sealing during operation. This reduces wear and minimizes noise from leakage.
Through-type heating system provides faster, more uniform temperature transfer, offering 50% greater efficiency than traditional heating plates. Optional PLC program control system available.
Complex tube belt design in the mixing chamber ensures excellent heat exchange and precise temperature control. Water-cooled rotors prevent material sticking, enhance temperature accuracy, and promote even dispersion.
