Client Overview
Our client is a South African construction company planning to expand into commercial concrete production. They required a reliable, efficient, and mobile solution to support multiple project sites while maintaining consistent quality and throughput.
Project Requirements
- Capacity: 20–30 m³/h
- Mobility: Easy to transport between sites
- Quality: Consistent mix with minimal downtime
- Commercial Viability: Suitable for small-scale commercial production and potential business expansion
Solution Provided
We supplied our 20–30 m³/h mobile concrete batching plant, designed for rapid setup and flexible operation. Key features include:
- Modular Design: Quick assembly and disassembly to move between sites efficiently
- Precision Weighing: High-accuracy aggregate, cement, and water dosing for consistent concrete quality
- Automation: PLC-controlled batching system for ease of operation and reduced labor
- Durability: Robust components suitable for South Africa’s demanding construction environments
Mobile Batching Plant — 20–30 m³/h Configuration
After a comparative evaluation of five equipment suppliers, the client selected a twin-shaft mixer mobile batching plant rated at 20–30 m³/h. The unit was chosen for its rapid site setup (under 8 hours), and integrated automation for mix design control.
| Parameter | Specification |
|---|---|
| Theoretical output | 20–30 m³/h (rated); 25 m³/h consistent commercial output |
| Mixer type | Twin-shaft compulsory mixer, 500L discharge volume |
| Aggregate storage | 3 × 8 m³ aggregate bins (19 mm, 13.2 mm, crusher dust) |
| Cement silos | 2 × 50-tonne bolted steel silos |
| Weighing system | Electronic load cells, ±0.5% accuracy |
| Control system | PLC-based with touch screen, mix design memory & batch reporting |
| Water supply | 2,000 L on-board tank + mains/borehole connection |
| Power requirement | 45 kW; compatible with 3-phase generator (diesel backup) |
| Transport configuration | Semi-trailer mounted |
| Setup / breakdown time | 4–8 hours (levelling, silo connection, calibration) |
Results
- The plant successfully produced high-quality concrete across multiple sites, supporting the client’s initial commercial projects.
- Setup and relocation time reduced significantly compared with conventional stationary plants.
- The client reported improved operational efficiency, reduced labor costs, and high customer satisfaction from their end clients.
Client Feedback
“The mobile batching plant has allowed us to launch our commercial concrete business quickly and reliably. Its mobility and consistent performance exceeded our expectations.”
Why Mobile Suits the South African Market
South Africa’s construction market presents a distinctive case for mobile batching: projects are widely dispersed, infrastructure for permanent plant establishment is often unavailable, and the cost of purchased ready-mix is high relative to raw material inputs. A 20–30 m³/h mobile plant sits at the optimal intersection of output capacity, capital cost, and logistical flexibility — large enough to service commercial pours and small housing estates, compact enough to relocate within a business day. For contractors exploring the same path, the critical success factors are rigorous mix design calibration from the outset, investment in a reliable water supply strategy, and a clear sales pipeline before commissioning to ensure utilisation targets are met from month one.
Conclusion
Our 20–30 m³/h mobile concrete batching plant proved to be an ideal solution for South African companies seeking flexible, commercial-grade concrete production. Its combination of mobility, quality, and efficiency enables construction businesses to scale operations without compromising performance.
