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.
mtUCC
The Up Current Classifier for sharp, single-stage classification with throughputs from 2 to 500 tph.
Every design feature contributes to maintaining a stable classification environment.
Sharper Classification. Stronger Recovery.
The Mineral Technologies Up Current Classifier (mtUCC) is engineered for simplicity and reliability – giving you sharp, single-stage separation without the usual complexity. With no moving parts and no need for constant adjustment, it delivers steady performance even when feed conditions change. It’s purpose-built to integrate with our spiral systems, helping you recover more with less effort.
- Controlled up-current A carefully regulated upward water flow creates a stable classification environment.
- Natural particle response Heavier particles settle while lighter particles remain suspended within the hindered-settling zone.
- Stable classification Consistent bed density produces repeatable separation and reliable product quality.
- Ready for downstream recovery A balanced overflow integrates directly with spiral circuits or other beneficiation stages.
Technical Features
Uses controlled upward water flow to classify particles by size and density, separating lighter material to overflow while heavier particles report to underflow.
Suitable wherever accurate particle-size or density classification improves downstream processing.
- 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.
- 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.
- 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.
- 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.
