In the remote and rugged terrains of Papua, Indonesia, PT Freeport—one of the country’s most reputable mining companies—is laying the foundation for a new power plant. Faced with a hardened project floor and high-volume concrete requirements, the client needed a dependable and high-efficiency concrete solution. To meet these needs, Aimix delivered and installed the AJ-90 stationary concrete batching plant, providing a reliable on-site concrete supply that now powers their critical infrastructure development.
Challenge: Complex Ground and High Concrete Demand
The construction site posed two major challenges: a hardened base that required reinforced foundation work, and a high, consistent demand for quality concrete throughout the development of the power plant. The customers needed more than just raw production capacity—they required precision, efficiency, and reliability to ensure project continuity without delays or material loss.
Tailored Solution: AJ-90 Stationary Batching Plant
To address these challenges, Aimix supplied an AJ-90 stationary concrete plant equipped with a high-performance SICOMA twin-shaft mixer, four independently weighed aggregate bins, and two vertical cement silos. This robust configuration provided the production strength needed to handle the demanding work environment while delivering consistent, high-quality concrete.
Smart Integration: Advanced Control for Smarter Operation
The AJ-90 plant features an integrated control system that simplifies the operation. With one-click start/stop functionality and dual operation modes—via both PLC touchscreen and manual button panel—the system offers flexibility and operational reliability.
- 30% reduction in startup time
- 50% decrease in operational error rates
- Enhanced adaptability for operators with different skill levels
These capabilities ensure uninterrupted concrete production while minimizing human error and training overhead.
Precision Feeding System: Reducing Waste, Increasing Output
The plant’s automated feeding system includes remote control and smart calibration functions. Operators can fine-tune material ratios and feeding speeds through mobile terminals, supporting:
- 20% increase in production continuity
- 10% reduction in raw material waste
- Real-time material stock warnings and automatic refilling
This system ensures that concrete quality remains consistent while reducing environmental and operational costs.
Premium Mixing Technology: Built to Last
At the heart of the plant lies a SICOMA twin-shaft concrete mixer, a globally recognized brand known for its superior durability and mixing precision.
- 50% longer lifespan of critical components
- Maintenance intervals extended to over 6,000 hours
- Lower long-term ownership and servicing costs
This mixer guarantees high homogeneity of concrete and supports the continuous, high-output operation demanded by the power plant construction project.
Outcome: Plant in Full Operation and Meeting Site Needs
The AJ-90 concrete plant has now been fully commissioned and is operating smoothly at the Papua site. It is successfully fulfilling the on-site demand for quality concrete, contributing to the fast and efficient construction of the power plant.
PT Freeport is now empowered with a solution that not only meets today’s project needs but also offers long-term reliability and operational efficiency. Through innovation, advanced control, and premium components, we’re proud to support the company in powering Indonesia’s future—starting from the ground up. Facing a challenging build?
