The Karvil 50L Kneader is a custom-engineered solution built to handle highly abrasive and high-viscosity materials with exceptional durability. It perfectly integrates powerful mixing, precise temperature control, and superior wear protection. This model is ideal for compounding Alumina (Aluminum Oxide), Bauxite, and various high-performance ceramics, refractory materials, and specialized alloy powders.
Designed for Extreme Abrasives: Specifically built to resist the intense wear characteristics of Alumina and Bauxite. All critical material-contact parts—including kneading blades and mixing chamber walls—are treated with an extremely hard Tungsten Carbide coating.
Extended Service Life: Wear resistance is dramatically increased compared to standard stainless or alloy steels, significantly reducing machine downtime and maintenance costs.
Technical Parameters
FAQ
Q1: Why is Tungsten Carbide coating necessary for this machine?A: Tungsten Carbide is applied to the mixing blades and contact surfaces to provide extreme wear resistance. It is essential when processing highly abrasive materials like Alumina and Bauxite, which quickly degrade standard stainless steel, ensuring a dramatically longer lifespan and preventing metal contamination.
Q2: What is the primary function of the vacuum system?A: The high-vacuum system (up to -0.095 MPa) serves to degas the material during mixing. It removes trapped air bubbles, moisture, and volatile components, which is critical for achieving high density and purity in end products like advanced ceramics and high-performance powders.
Q3: How does the screw discharge mechanism benefit production?A: For high-viscosity, non-flowing pastes, conventional tilting can be difficult and leave residue. The screw discharge mechanism actively extrudes the finished product quickly and completely, ensuring faster batch turnover and virtually zero material waste.
Q4: Is the 50L capacity suitable for R&D or production?A: The 50-liter working capacity is versatile. It is ideally suited for R&D departments to finalize formulas and scale-up trials, as well as for small to mid-batch specialized production where material volume is high-cost or limited.
Q5: Can this machine handle materials that generate heat during mixing?A: Yes. The machine is equipped with a Cooling Jacket around the mixing chamber. This allows for the circulation of cold water or thermal fluid to precisely manage and dissipate the heat generated by the intense shear mixing, ensuring optimal process temperatures.
Q6: Can the machine be customized beyond the Tungsten Carbide coating?A: Absolutely. While the Tungsten Carbide is a core feature for this specific application, we offer customization in several areas, including motor power, temperature control range (heating and cooling options), and PLC automation levels, to perfectly fit your unique process requirements.
Q7: What industries commonly use this specific configuration?A: This high-end configuration is mainly used in Advanced Materials, specifically in the production of:
High-performance ceramics (Alumina, Zirconia)
Refractory and abrasive compounds
Specialized powder metallurgy (MIM)
High-viscosity chemical pastes.
