In a fast-developing construction project in South Africa, concrete supply became a critical bottleneck that directly affected project scheduling and on-site efficiency. To solve this challenge, an AJ90 concrete batching plant was introduced and successfully installed in Johannesburg, providing a stable and high-efficiency solution for continuous concrete production.
Project Overview: Increasing Demand Beyond Existing Capacity
In early 2025, our client in Johannesburg started a new project that required continuous concrete supply. As construction progressed, the existing mixing equipment became insufficient to meet growing demand, leading to production limitations and reduced efficiency on site.
To solve this issue, an AJ90 concrete batching plant was selected. The system provides a stable output capacity of approximately 70–90 m³/h and was successfully installed and commissioned in 2026, ensuring reliable concrete production for the project.
Key Challenge: Production Bottleneck and First-Time System Adoption Risk
The project faced two main challenges during execution.
A solution was required that could not only increase production capacity but also ensure ease of operation and long-term reliability.
Equipment Selection: AJ90 for Stable Medium-Scale Production
After technical evaluation of multiple options, the AJ90 stationary concrete plant was selected as the most suitable solution for the project.
The decision was based on the following key factors:
- Stable production capacity of 70–90 m³/h for continuous supply
- Twin-shaft mixer ensuring uniform and high-quality concrete output
- PLC intelligent control system enabling accurate and automated batching
- Strong adaptability for medium-scale infrastructure and building projects
This configuration provided a balanced solution between production efficiency, operational stability, and installation flexibility.
System Configuration: High-Precision Batching and Storage Design
A major advantage of this project lies in the plant’s high-precision material handling system, which significantly improves batching accuracy and reduces material waste.
The configuration includes:
3 × 100-ton cement silos, ensuring continuous cement supply and reducing downtime caused by material interruption.
4 separate aggregate bins, enabling classified storage of different raw materials for stable and controlled feeding.
Independent weighing system for all materials, including cement, aggregates, water, and additives.
This independent weighing structure ensures that each material is measured precisely before entering the mixing process, resulting in consistent concrete quality and improved structural reliability.
Installation and Commissioning: On-Site Engineering Support
The installation and commissioning in Johannesburg were completed with the support of our engineer. Our engineer were on-site to guide the installation process, carry out system debugging, and ensure all equipment operated correctly.
During commissioning, key systems were tested and adjusted to ensure stable performance and accurate batching. We also provided operator training, covering daily operation and basic maintenance to ensure safe and efficient use of the plant. With on-site technical support, the equipment was successfully put into stable operation.
Operational Performance: Stable Production and Improved Construction Efficiency
After commissioning, the AJ90 batching plant entered stable operation and successfully met the project’s continuous concrete demand.
The key performance improvements included:
- Stable and uninterrupted concrete supply during peak construction periods
- Higher batching accuracy through independent weighing system
- Reduced material waste and improved cost control
- Faster construction progress due to improved supply reliability
- Simplified operation after structured training
Overall, the plant significantly improved construction coordination and eliminated previous production constraints. The client also expressed high satisfaction with both the equipment performance and the on-site technical support provided throughout installation and commissioning.
Conclusion
This project demonstrates how a properly selected concrete batching plant can effectively resolve production limitations and improve construction efficiency. The AJ90 plant delivered stable performance and reliable concrete supply throughout the project.
For clients facing similar project requirements, we provide tailored batching plant solutions and full technical support to help ensure smooth installation, stable operation, and successful project delivery.
