Rocktec designed and built a high-performance crushing and screening plant for Southern Quarries at their Sellicks Hill site in South Australia. This plant supports secondary and tertiary processing and includes refurbished and new equipment for improved flexibility, stockpiling, and throughput.
Project Overview: Crushing and Screening System at Sellicks Hill Quarry
- Client: Southern Quarries Pty Ltd
- Location: Sellicks Hill, South Australia
- Industry: Quarrying / Aggregates
- Scope: Design and install a crushing and screening plant including crushers, screens, conveyors, and radial stackers
The Challenge: Combining Refurbished Equipment with New Infrastructure
Southern Quarries needed a system that could process multiple grades of product, using a mix of refurbished equipment and new design. The crushing and screening plant also had to provide flexible stockpiling, consistent output, and integration with an existing barmac crusher. Most importantly, it needed to support seven distinct product splits for use in roading and concrete.
Rocktec’s Solution: Modular Screening and Stockpiling System
Rocktec delivered a complete system engineered to optimise material flow and product control. Key components included:
- Three refurbished cone crushers for secondary crushing
- Two 20′ x 8′ screens to separate core material grades
- A barmac-fed tertiary screen with flexible discharge setup
- Radial stackers and conveyors for stockpile management
- Seven finished product splits for road base, dust, and concrete aggregates
Additionally, Rocktec used process flow modelling and simulation tools to guide layout decisions and improve plant efficiency from the ground up.
Installation Process: From Design to Full Commissioning
- Planning: Rocktec modelled material flow and final output targets with the client.
- Preparation: Equipment was refurbished and adapted to the new layout ahead of installation.
- Installation: The plant was installed with radial stacking capabilities and seamless material handoff between stages.
- Commissioning: The system was tested and tuned to ensure reliable production and grading accuracy.
Results and Benefits
- Multiple Output Grades: The plant produces seven consistent material grades, ready for road and construction use.
- Increased Efficiency: Refurbished screens and crushers paired with new layouts reduced handling time and boosted flow.
- Stockpiling Flexibility: Radial stackers allow for dynamic product segregation and easier loadout.
- Process Control: Flow simulation ensured smarter conveyor routing and output accuracy from day one.
Conclusion: A Versatile Crushing and Screening Plant for Southern Quarries
This crushing and screening plant shows how Rocktec combines new design with existing resources to build systems that perform and scale. At Sellicks Hill, Southern Quarries now benefits from a reliable, multi-product setup that supports long-term production targets with confidence.
