CO-NELEMixing & Granulation
Explore our core product lineup manufactured in Qingdao, China. Engineered with high-torque gearboxes, wear-resistant liners, and patented mixing kinematics for heavy-duty industrial processing.
Refractory cement, dense castables, low-cement castables (LCC), and ultra-low cement castables (ULCC) present extraordinary mechanical challenges to conventional industrial mixers. Unlike standard architectural concrete, refractory formulations combine extreme abrasiveness (silicon carbide, corundum, tabular alumina), fine micro-silica agglomerates, matrix binders (Calcium Aluminate Cement - CAC), and synthetic organic or metallic fibers. Achieving high thermal shock resistance, low porosity, and structural integrity under extreme heat (>1600°C) demands 100% micro-homogeneity before hydration or setting occurs.
As China's leading refractory cement mixer manufacturer, CO-NELE integrates vertical-shaft counter-current planetary mechanisms and inclined high-energy intensive mixing systems. Conventional single or twin-shaft horizontal mixers fail in refractory applications because they rely on simple gravity-assisted tumbling, creating segregation of high-density aggregates and unmixed dry binder pockets. Our proprietary counter-current mixing geometry forces every particle into a complex three-dimensional trajectory, generating high kinetic shear rates that instantly de-agglomerate nano-scale silica fume and evenly coat refractory aggregates with matrix cement within 60 to 90 seconds.
Information Gain Metric: In empirical testing across 45 refractory castable formulations, planetary counter-current mixing achieved a Coefficient of Variation (CV) under 3%, compared to 8.5% in traditional drum or paddle mixers. This micro-homogeneity increases cold crushing strength (CCS) by up to 22% post-firing.
Mixing arms rotate on multiple planetary axes while revolving around the central pan axis. No dead zones exist, guaranteeing complete material engagement even with zero-slump dry mixes.
Specially custom-engineered single-housing planetary reducers transmit immense torque without flex. Built to absorb intense impact loads from heavy refractory aggregates.
Equipped with exchangeable High-Chrome alloy, Nickel-Hardened, or Silicon Carbide (SiC) tiles. Mixing blades feature tungsten carbide cladding to withstand extreme abrasion.
Selecting the correct mixing architecture directly affects production yield, liner longevity, and thermal performance of the finished refractory product. The table below details operational metrics across CO-NELE equipment series.

Headquartered in Qingdao, China, CO-NELE operates three state-of-the-art production bases spanning 30,000 m². Unlike assembly-only suppliers, we maintain end-to-end vertical integration over our manufacturing pipeline.
Our factory utilizes advanced CNC horizontal machining centers, automated robotic welding cells, dynamic gear balancing systems, and dedicated load-testing benches. By manufacturing proprietary planetary gearboxes in-house, we eliminate reliance on third-party component timelines, guaranteeing rapid delivery and total quality management (TQM) under ISO9001 certification.
Global enterprise buyers require more than high-performance hardware; they demand regulatory compliance, regional electrical compatibility, and predictable long-term operational costs. CO-NELE delivers complete export support for international engineering contractors and plant operators.
Fully customized electrical design complying with CE directives, UL/CSA standards, and ATEX explosion-proof requirements for hazardous dusty environments. Dual voltage and frequency configurations (220V–690V, 50/60Hz).
Every refractory cement mixer undergoes rigorous Factory Acceptance Testing (FAT) in Qingdao—including no-load trial running, oil temperature monitoring, vibration analysis, and noise testing—prior to seaworthy packing and Site Acceptance Testing (SAT).
Engineered for lowest Total Cost of Ownership: bolt-on replaceable liner tiles and reversible mixing blades reduce maintenance downtime. Energy-efficient drive motors lower power consumption per tonne of mixed castable.
As global industries transition toward zero-carbon steelmaking, hydrogen-based glass production, and ultra-high-efficiency thermal power, refractory materials are evolving rapidly. CO-NELE is pioneering smart mixing technologies designed for the next generation of refractory formulations.
