Mining currently progresses in a south- erly direction across 11 production benches, with the southern end of the pit reaching depths of approximately 110 m. Bench heights range between 10 m and 13 m, while some bench lengths extend up to 400 m. One of the operation’s key design advantages is the long-bench layout, which allows both blue and brown rock to be mined simultaneously from the same bench. “The bench layout gives us the flexibility to manage material flow far more efficiently,” he explains. “It allows us to optimise blend- ing while minimising unnecessary move- ment of equipment.” Large-scale production capability Peninsula Quarry’s installed crushing and screening infrastructure is designed to produce approximately 1,2 million tonnes of aggregate annually, placing it among the country’s highest-volume hard-rock aggre- gate quarries. The operation runs multiple crushing circuits configured to maximise throughput while maintaining product quality and operational flexibility. Primary Plant A consists of a 38/48 Osborn jaw crusher fed by apron feeder and supported by a Sandvik H6800 cone crusher. Material is delivered to the plant by 35 t articulated dump trucks operat- ing at feed rates of approximately 450 t/h. Primary Plant B incorporates a 30/42 Osborn jaw crusher with vibrating grizzly feeder, together with a Sandvik CH440 cone crusher and a VSI crusher. Operating at feed rates of roughly 250 t/h to 275 t/h, this circuit produces a wide range of products including G1 to G7 layer-work materials, 20 mm concrete stone and road stone products. The inclusion of the VSI crusher is par- ticularly important for improving particle shape in concrete aggregate applications, where cubical stone plays a major role in achieving quality concrete performance. Further downstream, the tertiary plant includes multiple screens, Sandvik H4800 and H3800 cone crushers and a Barmac VSI crusher to produce aggregate fractions ranging from 7 mm through to 53 mm con- crete stone. Additional infrastructure includes a sand plant, washing plant and an onsite AfriSam ready-mix facility, all of which contrib- ute towards improving product value and reducing waste. Kruger notes that there are already plans under consideration to increase produc- tion capacity even further in response to
Peninsula Quarry’s integrated approach to mining, crushing and material handling supports consistent production performance across its extensive aggregate operations.
AfriSam’s Peninsula Quarry demonstrates how world-class aggregate production can successfully coexist with strong environmental performance, maintenance discipline and uncompromising safety standards.
