CO-NELEMixing & Granulation
Explore our premium range of asphalt and concrete mixers engineered for heavy-duty operational stability, high thermal retention, and micro-homogeneous dispersion.
Argentina's civil engineering landscape is undergoing a decisive transition. As key transportation networks such as Ruta Nacional 40, Ruta Nacional 9, and strategic energy haul routes surrounding the Vaca Muerta shale formation undergo major expansion, road contractors face unyielding demands for asphalt quality, production rate, and thermal consistency.
Hot Mix Asphalt (HMA), Stone Matrix Asphalt (SMA), and polymer-modified bitumen mixtures required across Argentine provinces must endure severe microclimatic variations—from the freezing, high-altitude alpine shear of the Andes to the humid, heavy-tonnage logistics corridors connecting Greater Buenos Aires, Rosario, and Córdoba. Modern asphalt mixing equipment must achieve absolute homogeneity without thermal degradation or aggregate segregation.
Why compulsory synchronized double-shaft mixing surpasses traditional drum or single-shaft systems in high-spec bitumen coating efficiency.
CO-NELE twin shaft asphalt mixers utilize synchronized counter-rotating shafts with offset paddle geometry. This creates an intense 3D turbulence zone where aggregate particles are dynamically suspended, enabling instant bitumen envelope encapsulation within seconds.
Equipped with multi-point high-pressure bitumen spray bars, the system delivers liquid asphalt uniformly across the fluidized particle cloud. This prevents localized bitumen pockets, reduces binder usage variance, and minimizes dynamic viscosity breakdown.
Mixing arms and wear liners are cast from Ni-Hard alloy and High-Chrome cast iron (hardness exceeding HB 650). This guarantees extreme resistance against abrasive crushed granite, basalt, and silica sand typical of South American quarry feeds.

| AMS1500 | 1500 kg / batch | 2 x 30 kW | 35 - 45 s | ± 0.2% | High-Temp Thermal Shield |
| AMS2000 | 2000 kg / batch | 2 x 37 kW | 30 - 40 s | ± 0.15% | Thermostatic Oil / Electric Heat |
| AMS3000 | 3000 kg / batch | 2 x 55 kW | 30 - 40 s | ± 0.15% | Fully Automated Thermal Loop |
Combining 20+ years of industrial mixing expertise, heavy industrial machining infrastructure, and seamless international shipping logistics.
Unlike standard machinery assemblers that outsource critical drivetrain components, CO-NELE designs and manufactures specialized heavy-duty planetary gearboxes and twin-shaft sync gearboxes in-house at our Qingdao production complex. Each unit undergoes 100% full-load torque testing and thermal benchmarking prior to export.
This eliminates common drivetrain failures caused by the severe shock-loads of dry aggregate charging, securing uninterrupted plant operation during high-tonnage paving schedules in remote locations across Argentina.
Importing directly from China allows Argentine infrastructure firms to eliminate intermediate agency markups, reducing capital expenditure (CapEx) by 30% to 45% compared to European alternatives while preserving top-tier component quality (Siemens PLC, Schneider electronics, SKF bearings, Hardox liners).
In mountain projects across Salta and Jujuy, low ambient temperatures accelerate hot asphalt cooling. CO-NELE twin shaft mixers feature insulated mixing chambers and automated thermal control to maintain ideal discharge temperatures (160°C - 175°C).
Oilfield access highways require ultra-dense, rut-resistant SMA asphalt mixes containing high polymer content. Twin shaft compulsory kinematics guarantee thorough dispersion of SBS polymers and mineral fillers without clumping.
Urban paving demands fast batch turnarounds and rapid plant setup. CO-NELE compact asphalt batching units integrate seamlessly with mobile batching infrastructure for quick deployment across Greater Buenos Aires municipal paving contracts.
All exported CO-NELE asphalt and concrete mixing machinery is built to strictly align with local electrical regulations in Argentina:

Twin shaft batch mixers provide precise control over binder proportioning, mixing duration, and aggregate thermal equilibrium. While drum mixers rely on continuous tumbling where bitumen coating uniformity can fluctuate, twin shaft compulsory mixers force aggregate particles into a 3D fluidized bed. This achieves micro-homogeneity with a Coefficient of Variation (CV) below 3% in just 35 seconds—critical for passing strict Vialidad Nacional (National Highway Department) specs in Argentina for Stone Matrix Asphalt (SMA) and polymer-modified friction courses.
CO-NELE AMS series asphalt mixers support indirect or direct RAP entry points up to 40% batch proportioning. The twin shaft kinematics quickly transfer heat from super-heated virgin aggregate to the cold RAP particles without overheating the fresh bitumen. This prevents thermal degradation (aging) of the bitumen binder while ensuring uniform rejuvenator dispersion throughout the recycled blend.
Equipped with high-chrome alloy wear plates (hardness > HB 650) and Ni-Hard paddle tips, CO-NELE twin shaft mixers typically deliver 90,000 to 150,000 batch cycles on standard stone aggregates, and 40,000 to 60,000 cycles on highly abrasive quartz-rich stone or refractory castables. All liner tiles are modular and bolt-on, enabling targeted replacement during routine maintenance shifts without complete lining teardown.
All machinery is custom-built to match Argentina's 380V/50Hz industrial electrical grid and supplied with bilingual CE/IRAM compliant electrical documentation. Shipments depart directly from Qingdao Port to the Port of Buenos Aires or Port of Rosario in standard flat-rack or open-top containers. CO-NELE provides complete shipping manifests, certificate of origin (Form A/CO), and tariff classification guidance to streamline customs clearance through Argentine customs (AFIP/DGA).
Yes. In addition to remote telemetry diagnosis via cloud-connected PLCs, CO-NELE dispatches experienced field commissioning engineers for on-site plant assembly, calibration, trial batching, and operator safety training. Resident engineering support can be arranged across provinces ranging from Neuquén to Santa Fe.
