In the increasingly competitive refractory industry, product homogeneity and stability are crucial to its service life and performance. Recently, industry-leading CO-NELE launched the CR11 Series Intensive Mixer. With its superior design and efficient mixing capabilities, it is becoming the preferred equipment for global refractory manufacturers seeking to enhance the quality of their castables.
Why do refractory castables require "intense" mixing?
Challenges of Traditional Mixing Methods
Traditional twin-shaft mixers or drum mixers often face the challenge of uneven mixing when processing refractory castables. Aggregates, fines, micropowders, and binders in castables vary significantly in density and particle size. Gentle mixing methods struggle to achieve the desired microscopic uniformity, resulting in performance fluctuations, poor workability, and even compromised corrosion resistance and service life of the final product.
CO-NELE's Solution: Combining Strength and Precision
The CO-NELE CR11 Intensive Mixer utilizes a unique "three-dimensional countercurrent" mixing principle, combining high-speed mixing tools with counter-rotating feed plates to create intense convection, shearing, and diffusion within the mixer. This multi-dimensional, compound motion instantly breaks down material agglomerates, ensuring that every aggregate particle is perfectly encapsulated by the binder slurry. This results in ultra-high-quality uniformity from macro to micro, perfectly meeting the production requirements of refractory castables.
Core Technical Innovations of the CO-NELE CR11 Intensive Mixer
High-Efficiency Three-Dimensional Countercurrent Mixing System
The core of this system is a mixing star that orbits around its main axis while simultaneously rotating at high speed. This motion ensures seamless mixing, enabling thorough mixing of high-viscosity, multi-component refractory castables in a very short time, significantly shortening production cycles and demonstrating the high efficiency of CO-NELE mixing equipment. Rugged and Durable Structure and Sealed Design
Recognizing the high wear resistance of refractory materials, the Co-Nel CR11 Intensive Mixer's impellers and linings are constructed of high-chromium, wear-resistant alloy steel, ensuring an extremely long service life. Furthermore, an advanced sealing system effectively prevents leakage of fine powders, protecting the working environment and reducing material waste.
Intelligent Control System
The integrated PLC control system allows the operator to precisely set mixing time, speed, and feed sequence. Recipes can be stored and recalled, ensuring consistent product from batch to batch, providing a solid foundation for standardized and automated refractory production.
Practical Benefits for Manufacturers
Improved Product Quality: Significantly improved mixing uniformity directly translates into better flow properties, more stable bulk density, and enhanced corrosion resistance for the castable.
Increased Production Efficiency: Compared to traditional equipment, the Co-Nel CR11 Intensive Mixer can shorten mixing time by 30%-50%, achieving higher output per unit time.
Reduced Production Costs: Uniform mixing reduces binder usage and reduces scrap rates due to uneven mixing.
Enhanced Flexibility: This CO-NELE equipment can easily handle a wide range of refractory castable formulations, from ultra-low cement to cement-free, adapting to future product upgrades.
The CO-NELE CR11 refactory mixer is more than just a mixing device; it serves as a strategic partner for refractory manufacturers on their journey toward high-quality, efficient, and intelligent manufacturing. Its widespread application is redefining the production standards for refractory castables and driving technological advancement across the industry.
