CO-NELEMixing & Granulation
Engineered to deliver micro-homogeneity, rapid discharge, and low wear rates across diverse Brazilian industrial applications.
Brazil's construction and industrial sectors are undergoing a structural transformation. Driven by federal initiatives such as the Novo PAC (Programa de Aceleração do Crescimento), social housing expansions through Minha Casa, Minha Vida, and massive private investments in renewable energy infrastructure, the demand for high-spec concrete has reached an all-time high. From wind turbine foundation gravity rings in Bahia to metro tunnel linings in São Paulo and precast logistics hubs in Santa Catarina, engineering requirements are shifting rapidly from basic ready-mix concrete to high-performance, durable, and sustainable concrete formulations.
However, Brazilian concrete producers face unique geological and operational challenges. Aggregate properties vary widely across provinces—from hard, abrasive basaltic crushed stone in the Southern region to highly porous quartz sand in Minas Gerais and tropical clay-contaminated aggregates in North-Northeast Brazil. Traditional horizontal twin-shaft mixers and single-axis drum mixers frequently suffer from aggregate segregation, incomplete dispersion of fine cementitious additives (such as silica fume and fly ash), and premature wear of pan liners.
As a leading China Planetary Concrete Mixer Manufacturer, CO-NELE provides state-of-the-art compulsory counter-current mixing technology specifically engineered to solve these localized challenges. By combining German-inspired mechanical design with robust Chinese supply chain efficiency, CO-NELE delivers planetary concrete mixers that achieve micro-homogeneity with a Coefficient of Variation (CV) below 5%, ensuring compliance with Brazilian ABNT (Associação Brasileira de Normas Técnicas) standards NBR 6118 and NBR 12655.
Understanding the physics of forced vertical-shaft planetary motion vs. twin-shaft horizontal mixing.
Unlike twin-shaft mixers where aggregate accumulates along shaft ends or center discharge troughs, a planetary mixer operates with dual motion: the mixing arms rotate around their own axis while simultaneously revolving around the central axis of the mixing pan. This guarantees 100% swept coverage of the pan floor every 4 revolutions.
For recipes containing steel fibers, synthetic micro-fibers, or color pigments (common in dry-cast paving blocks produced in Paraná), CO-NELE planetary mixers can be equipped with high-speed fly-cutters. These auxiliary rotors generate intense localized shear forces, breaking up agglomerates in seconds without damaging fragile additives.
Energy consumption in Brazilian industrial plants is subject to strict peak-load tariffs. CO-NELE's custom-engineered heavy-duty planetary reducers transmit mechanical torque with over 94% efficiency. This yields up to 20% lower kWh power consumption per cubic meter mixed compared to European pan mixers.
From metallurgical refractories in Minas Gerais to precast block factories in Rio Grande do Sul.

Dry-cast concrete for pavers and retaining wall blocks demands extremely low water-cement ratios (w/c < 0.32) and rapid cycle times. CO-NELE MP and CMP planetary mixers ensure uniform moisture distribution across the entire batch in less than 60 seconds, eliminating density variations between molds and minimizing scrap rates.

UHPC requires mixing fine silica powder, quartz sand, high-dose superplasticizers, and steel fibers. CO-NELE CMPS series mixers with planetary fly-cutters prevent fiber balling, producing a self-consolidating batch with ultra-high compressive strength (>150 MPa) ideal for harsh marine corrosion environments along Brazil's coastline.

Brazil's steel and mining sector relies heavily on refractory castables for furnace linings and ladles. CO-NELE intensive planetary mixers handle highly abrasive high-alumina and silicon carbide raw materials, fitted with diamond-hardened chromium carbide wear plates to endure thousands of operating hours.
Location Focus: Industrial Hubs in Campinas & Joinville
Uniform raw material mixing (silica sand, soda ash, limestone, cullet) is essential for glass melt quality. CO-NELE specialized glass industry batch mixers provide dust-tight sealings, stainless steel option liners, and automated liquid spraying bars to meet high international standards.
Unlike assemblers who buy standard off-the-shelf gearboxes, CO-NELE designs and machines its planetary gearboxes in-house across three production bases in Qingdao. Each reducer is subjected to rigorous bench-test load trials to handle sudden torque spikes caused by heavy concrete batches.
Brazilian buyers traditionally faced high CAPEX when sourcing premium mixers from Western Europe. CO-NELE provides equivalent mixing performance and mechanical longevity at significantly optimized costs, giving Brazilian contractors a clear competitive edge in public tenders.
Wear parts (mixing blades, scrapers, liner plates) are engineered with modular bolt-on designs using high-chrome alloy steel (HB > 600). Spare parts are kept in standard stock for immediate air/ocean dispatch to major ports such as Santos, Paranaguá, and Rio de Janeiro.

Send Inquiry NowFuture concrete manufacturing requires real-time feedback loops. CO-NELE is pioneering the integration of high-frequency optical and microwave moisture sensors directly into the planetary pan floor. By measuring slump changes during the live mixing cycle, our Siemens-PLC integration automatically adjusts water and admixture dosing to guarantee consistent slump for every truck load leaving the plant.
With remote telemetry modules, Brazilian plant operators can monitor gearbox temperatures, oil viscosity, vibration spectrums, and motor currents in real time via cloud platforms. Predictive maintenance alerts notify managers before mechanical failures occur, minimizing unplanned downtime in critical concrete batching projects.
CO-NELE customized electrical control cabinets meet Brazilian safety standard NR-12 (Segurança no Trabalho em Máquinas e Equipamentos) and NR-10 (Instalações e Serviços em Eletricidade), featuring safety interlocks, emergency stop circuits, and dual-channel safety relays.
Recognizing Brazil's diverse regional grid voltages (220V, 380V, 440V at 60Hz), CO-NELE offers premium WEG electric motors or custom-wound IP55/IP65 heavy-duty motors certified for continuous duty under tropical temperature conditions.
We provide comprehensive export documentation, including Form E/CO certificates, Bill of Lading, custom HS code classifications (8474.31), and detailed English/Portuguese operation manuals to ensure fast customs clearance through Brazilian customs.
