Quadra SA Brings MCT & Sicoma Mining Solutions to South Africa
South Africa’s mining sector remains a foundational driver of the national economy—accounting for over 6% of GDP and serving as the global hub for Platinum Group Metals (PGMs) from the Bushveld Complex, alongside historic ultra-deep gold extraction across the Witwatersrand Basin.
However, as subterranean operations extend deeper, mines face severe geomechanical stress, requiring robust structural ground control and rapid backfilling.
Long recognised as an industry leader in turnkey concrete brick, block, and paving manufacturing equipment, Quadra South Africa has expanded its reach into the mining sector. Through strategic partnerships, Quadra SA supplies South African mines with world-class technology from two industry leaders: Sicoma Heavy-Duty Twin Shaft Mixers and MCT Advanced Underground Backfilling Systems.

Heavy-Duty Mixing Technology: Sicoma Twin Shaft Mixers
In South African underground mining, twin shaft mixers are the industry benchmark for processing paste tailings, hydraulic backfill, and structural shotcrete. High-tonnage mining environments require robust mixing action capable of handling dense, highly abrasive slurries under continuous, heavy-duty operational cycles.
Through its partnership with Sicoma, Quadra South Africa supplies the globally proven MAO Twin Shaft Mixers and MAO C Continuous Twin Shaft Mixers, specifically engineered for these harsh conditions:
Rapid Slurry & Paste Homogenisation: Dual counter-rotating shafts equipped with synchronised paddles generate intense mechanical shear, ensuring complete cement hydration and uniform mixture density in short cycle times.
Superior Wear Protection: Mine tailings cause severe abrasive wear. Sicoma twin shaft units feature extra-thick Ni-Hard cast iron liners and heavy-duty steel paddles built for maximum operating life in aggressive SA mining environments.
High-Volume Continuous Output: For high-capacity shaft operations, Sicoma’s continuous units deliver outputs exceeding 300 m³/hr to match large-scale production requirements.
Heavy-Duty Planetary Gearboxes: Engineered to withstand high shock loads when starting under full slurry load, minimising operational downtime and lowering the total cost of ownership.
Underground Stabilisation Technology: MCT Backfilling Systems
While high-efficiency mixing is vital for slurry preparation, achieving structural safety underground requires dedicated backfill batching, storage, and injection systems. Maintaining stope stability and filling void space are critical to worker safety and ground control in deep-level shaft mining.
Through MCT (Marcantonini Concrete Technology), Quadra South Africa delivers complete bi-component backfill batching and transport plants engineered specifically for subterranean civil and mining environments:
Automated Bi-Component Batching: Modular mixing units precisely proportion water, bentonite, cement, and retarder/accelerator additives with throughput capacities between 20–50 m³/hr.
High-Capacity Agitated Storage: Big-tank agitators equipped with continuous recirculation prevent slurry separation, settlement, and bleeding prior to subterranean injection.
High-Pressure Injection: Integrated with Clivio high-pressure grouting pumps (delivering working pressures up to 230 bar), MCT systems transport primary mixtures cleanly and reliably to the stope interface or TBM annular void.
Wireless Real-Time Telemetry: Remote digital management tracks grouting pressure, volume, W/C ratio, and cycle counts in real time, streaming critical operational data directly to central mine control rooms.
