Optimized hydraulics and tailored metallurgy across the entire ore beneficiation flowsheet: from grinding mills to hydrocyclones, froth flotation banks, and deep tailing disposal.
Operating Challenge: The most aggressive pumping duty in any concentrator plant. Ore pulp exits primary grinding mills with coarse unground rocks (up to 50-75 mm), sharp quartz fragments, and slurry density exceeding 60-70% solids by weight.
Deploy extra-heavy KY-10/8ST-AH or KY-14/12TU-AH fitted with high-wall Ultrachrome A05 castings (27% Cr, 62+ HRC). Impellers feature wide open passages and deep expelling vanes to prevent localized gouging and tramp metal cavitation.
Operating Challenge: Cyclone separation efficiency depends on non-pulsating, rock-steady inlet pressure. Any hydraulic surging causes coarse solids to contaminate cyclone overflow or fines to recycle into underflow, directly hurting mineral recovery.
Equipped with KY-8/6E-AH or KY-10/8ST-AH operating at optimum BEP (Best Efficiency Point). Precision CNC dynamically balanced impellers ensure zero hydraulic pulsation and sustained high mechanical efficiency (up to 78%).
Operating Challenge: Tenacious air bubbles trapped within flotation concentrates cause standard slurry pumps to air-lock, cavitate, and lose prime, causing flotation troughs to overflow valuable metal concentrate.
Deploy KY-AF Vertical Froth Pumps featuring integrated conical collection tanks and tangential vortex inducer blades. Air is continuously vented from the impeller eye, preventing air binding and ensuring smooth, uninterrupted froth delivery.
Operating Challenge: Pumping high-density thickened tailings across 5 to 15 kilometers to tailings storage facilities (TSF). Demands high discharge pressure (up to 4.5 MPa in multi-stage booster configurations) with extreme structural safety against casing burst.
Deploy KY-HH Multi-Stage Heavy Duty Slurry Pumps or high-pressure rated AH casings reinforced with ductile iron outer housings (QT500-7). Hydrostatically tested up to 6.0 MPa before shipment.
