Why it matters
Sharp Separation.No Fuss.
The mtUCC gives you fine particle classification in one clean step – improving recovery, product consistency, and circuit stability.
Where others rely on intricate valves and constant tuning, our design keeps things simple. By maintaining a stable hindered settling zone inside the unit, the mtUCC ensures dense particles settle where they should, while lighter material is cleanly removed. It’s stable, scalable, and perfectly at home in your MT circuit.
How it Works
Up Current.Steady State.Better Separation.
Slurry enters the UCC where an upward flow of water is introduced through the teeter zone. This controlled up-current creates a hindered settling environment in which particles experience both gravitational and drag forces.
Dense or coarse particles overcome the upward drag and settle downward into the underflow. Finer or lighter particles are suspended or carried upward with the water and report to the overflow.
By precisely regulating the rise rate and bed pressure, the UCC maintains a stable and uniform hindered-settling zone. This stability ensures predictable cut points, consistent bed density, and reliable separation performance – even when feed solids, particle size distribution, or throughput vary.
The result is a steady-state operating condition with defined stratification layers, allowing the UCC to deliver accurate, repeatable separations suitable for downstream spiral circuits or other beneficiation stages.
Technology
Unique Nozzle System – Purpose-designed teeter-water nozzles eliminate slurry back-seepage into the injection lines, maintaining clean water delivery and stable bed-pressure control. The geometry ensures even distribution across the teeter zone, improving separation consistency.
Refined Cone and Underflow Control – The cone profile, washwater locations, and valving arrangement are engineered for hydraulic stability and reliable underflow discharge. The design avoids the complex, failure-prone valve configurations seen in other classifiers—no bridging, no choking, just smooth, predictable operation.
Optimised Overflow for Downstream Spirals – Overflow launders can be configured to feed multiple MT spiral starts directly, offering a simple, integrated flow path. When paired with our MK9 riser tubes, the system delivers uniform head, balanced slurry distribution, and improved spiral performance.
Benefits
The result is a separator that not only classifies, but also enhances process efficiency and product consistency – making it a critical enabler of outcome certainty in modern mineral processing plants.
Stable, Predictable Operation
The simplified underflow control and uniform teeter-water distribution maintain a consistent hindered-settling zone, delivering reliable cut points and steady performance across variable feed conditions.
Direct Spiral Integration
Designed to interface seamlessly with MT spirals, the UCC provides balanced, controlled overflow via our MK9 riser tubes – minimising redistribution equipment and simplifying circuit layout.
Flexible Plant Fit
The compact body and configurable launder/underflow arrangements allow the UCC to slot into tight spaces or be retrofitted between existing spiral banks without major structural changes.
Extended Wear Life
Strategic use of wear-resistant materials in high-velocity and high-impact zones ensures long service intervals and reduced downtime in abrasive mineral environments.
Low Operating Cost
Efficient water usage, minimal instrumentation, and a mechanically simple discharge system reduce maintenance requirements and keep OPEX low over the equipment lifecycle.
Applications
The mtUCC is used wherever accurate density and size classification is essential:
Mineral Sands
Removal of silica and upgrading of heavy minerals.
Silica Sand
Particle sizing for high-purity industrial applications.
Iron Ore
Desliming and beneficiation.
Coal
Separation of low-density, high-ash material.
Frequently asked questions
Our UCC features a self-closing nozzle that ensures even water distribution and prevents back-seepage into the teeter water chamber, maintaining consistent fluidisation volume and pressure.
Depending on the duty and material characteristics, we use either dart valves or pinch valves to provide precise underflow control and reliable operation across a wide range of particle sizes and densities.
Yes. While we offer a standard instrumentation package, we can customise components to align with your site standards or project requirements.
Yes. We have field service and process specialists located globally who can assist with installation, commissioning, and performance optimisation.
The mtUCC model sizes vary from ~ 0.4 m2 to 12m2 open area. The throughput per unit area depends on the particle size and density in the feed as finer feeds generally require larger machines.
