In 2025, Uruguay is experiencing a “green-digital infrastructure boom,” with major projects like the Paysandú green hydrogen power plant and Montevideo light rail system commencing construction. This has driven a surge in demand for efficient, flexible concrete production equipment. Recently, EPDAS successfully completed production and full-unit testing of its YHZM35 mobile concrete batching plant, which has now departed for construction sites in Uruguay.
The client’s projects primarily involve municipal road rehabilitation, small-scale bridge and culvert construction, and supporting infrastructure development. These projects are geographically dispersed with relatively tight construction schedules. Consequently, the client explicitly requested equipment with excellent mobility and rapid relocation capabilities. This would enable flexible deployment across different construction sites according to project progress, thereby enhancing equipment utilization efficiency and reducing redundant investment costs. Against this backdrop, the EPDAS technical team further recommended and optimized the YHZM35 mobile concrete batching plant solution, laying a solid foundation for the project’s subsequent smooth implementation.
The mobile batching plant employs a modular manufacturing and assembly approach during production. Core components—including the mixing main unit, aggregate batching system, conveying devices, electrical control system, and mobile chassis structure—are processed and pre-assembled at distinct production stations.
Functional testing is conducted on components such as the mixing main unit, batching and metering system, and electrical system to ensure safe and stable operation. After completing all testing procedures, the equipment passes final factory inspection. Relevant technicians verify the equipment’s appearance, connection points, electrical markings, and accompanying documentation to ensure complete configuration and good condition.
A “modular packaging and precise securing” plan is formulated based on the structural characteristics of the concrete plant. The mixing main unit is mounted on a custom solid wood pallet base, wrapped externally with five layers of waterproof and rust-proof film. Critical components are fitted with impact-resistant guards, and the unit is secured to the pallet with four sets of bolts to prevent movement during transport. The electrical system is shipped in a separate crate filled with foam cushioning material. The crate is labeled “Moisture-proof, Fragile” and equipped with a hygrometer for real-time monitoring of internal conditions.
The YHZM35 employs a JS750 twin-shaft forced-action mixing drum with a theoretical hourly output of 35 cubic meters of concrete. In the Uruguay project, after adjusting for aggregate moisture content, it achieved a stable hourly output of 25-28 cubic meters. Operating on an 8-hour shift, its daily production capacity exceeds 200 cubic meters. This output level perfectly aligns with the construction pace of Colonia’s modern new city development—where daily concrete demand averages approximately 180 cubic meters. A single unit can fulfill core supply needs, eliminating the capital investment required for multiple units compared to traditional stationary batching plants.
Equipped with a PLD1200 triple-bin batching machine, it simultaneously stores three aggregates—sand, gravel, and crushed stone—with ±1% batching accuracy, ensuring precise mix ratios for C30-C50 concrete grades. Field tests conducted by the Uruguay team demonstrated that the produced C40 concrete achieved a 28-day compressive strength of 48.2 MPa, exceeding local standards by 10% and fully meeting the requirements for pouring beams and columns in high-rise buildings.
For energy efficiency, the ready mix concrete plant employs variable frequency motor technology, reducing standby energy consumption by 70%. It consumes only 5.2 kWh per cubic meter of concrete produced, compared to an average of 6.5 kWh/m³ for similar equipment in the Uruguayan market. This translates to annual electricity savings of approximately $12,000 (calculated based on 300 operating days per year). Additionally, the equipment is equipped with a dust recovery system achieving a 98% dust recovery rate, complying with Uruguay’s Environmental Air Quality Standards.
Compared to the fixed-type mixing plants commonly found in the Uruguayan market, the portable concrete batching plant eliminates foundation construction costs and allows flexible adjustment of its operating location based on construction progress, reducing concrete transportation distances. Calculated at the local concrete transportation cost of $0.8 per cubic meter-kilometer, this feature alone saves customers approximately $30,000 per month.
The successful export of the mobile concrete batching plant to Uruguay represents more than a simple equipment transaction; it demonstrates the core competitiveness of Chinese-made construction equipment in emerging South American markets. Moving forward, EPDAS will continue to deepen its presence in South America, developing highly adaptable construction equipment tailored to local climate, power supply, and construction practices. The company will provide South American clients with full lifecycle services, spanning equipment procurement to post-delivery operation and maintenance.
