A large-scale building materials production base in São Paulo,Brazil,has officially launched a fully automated concrete paving brick production line.The line's core equipment utilizes the CMP1000 vertical-shaft planetary concrete mixer and CMPS250 planetary concrete mixer(with a high-speed fly-knife mechanism)from Qingdao Conele Machinery,China,in conjunction with a high-end brick-making system from Besser,USA.This marks the deep penetration of mid-to-high-end concrete product equipment technology into the Latin American market.

Project Background and Challenges

Brazil's accelerated urbanization is driving infrastructure upgrades,surging demand for high-quality concrete paving bricks.Traditional production lines face three key challenges:
Poor material adaptability:Local aggregates are complex and contain significant amounts of industrial solid waste(such as slag and construction waste),leading to segregation and insufficient homogeneity with conventional mixing.
Efficiency bottlenecks:Low fiber dispersion efficiency in the production of fiber-reinforced paving bricks slows overall production.
High operation and maintenance costs:Frequent equipment leaks and wear lead to frequent maintenance stoppages.

The new production line,centered on"efficient mixing+intelligent molding,"addresses these challenges through collaborative equipment design between China and the United States.

Co-Nele Planetary Concrete Mixer for Brick making:Technological Breakthroughs
1.CMP1000 Planetary Concrete Mixer(1 cubic meter mixer):Large Capacity and Powerful Mixing
Planetary Motion Trajectory:Through a combination of rotation and revolution(25 rpm),it covers 100%of the mixing drum area,ensuring over 98%concrete homogeneity per cubic meter and completely eliminating aggregate segregation.
Wear-Resistant Design:The patented parallelogram blade structure allows 180°rotation and reuse,extending its lifespan by 40%.A hydraulically sealed discharge door prevents slurry leakage.
Suitable for Solid Waste Materials:The 37kW high-torque reducer crushes slag agglomerates and supports a 1500L feed capacity,meeting required solid waste blending ratios.
2.CMPS250:Flying Cutter Device Enhances Fabric Uniformity
Independently Driven Flying Cutter Unit:Adds a High-Speed Flying Cutter Shaft(over 500 r/min)
A Co-Nele engineer noted,"Dual machine synergy is key—the CMP1000 focuses on large-volume base material mixing,while the CMPS250 specializes in the concrete brick surface layer.This flexible configuration accommodates the production of multiple product categories."
3.Bessel Brick Machine:Innovative Forming Process
The production line is equipped with a Bessel vibrating machine,achieving seamless mixing and forming:
Servo Vibration Technology:Four-axis synchronous vibration(synchronization error 0.001 degrees)with 10,000 rps acceleration increases brick density by 30%,achieving a surface finish that meets stone-like standards.

Intelligent Material Adaptation:Dynamically adjusts feed rate and vibration frequency through an aggregate property sensing system,compatible with recycled aggregates from construction waste.

Quick Mold Change System:A pneumatic clamping device enables mold changes for curbstones,permeable bricks,and slope protection bricks within 15 minutes,supporting flexible production of"small batches and multiple categories."
Three Key Significances of the Project in Brazil
Environmental Benefits:The production line utilizes recycled aggregate from local construction waste,processing over 20,000 tons of solid waste annually.
Economic Benefits:Maintenance costs for Conele equipment are reduced by 60%(no slurry leakage,and reversible blades),while the Bessel table vibration system saves 30%energy.
Technical Demonstration:This is Latin America's first fully automated"planetary mixing+servo forming"paving brick production line,with a production capacity of 40 m³/h,a 200%increase over the existing line.
