Product Dewatering – KISA bucketwheels • Extremely low energy demand – 50hp installed for 1300 stph • Models to ~1700 stph • Excellent sand capture: >98.5% to >99.5% for extended bath models • Low residual moisture c.f. dewatering screen • Very low maintenance costs Superior sand dewatering
Simple Design & Operation • PU drainage mats • Leading edge Hardox 500 • Sliding chutes UHMWPE • SEW planetary drive • Standard pillow block bearings
Product Dewatering – KISA bucketwheels • Custom designs are available • Bath sized to give ~>99.5% recovery of down to 270 mesh sand – free settling conditions • Options : load sensitive VS automation, exotic materials of construction
Tailings Dewatering – case study • Up to 165 stph fine sand 70x270# in ~3,000gpm flow • Installed Price : Savings >$100k vs. pump/cyclones/DW screens • Energy: Savings ~$60k p.a. @ 6000 hrs, 10c/kWh • Annualized spares savings ~$7k • Similar sand recovery & cake moisture • Simplicity! • Superior investment
FUTURE DEVELOPMENTS • Enhanced washing of manufactured sand – or well liberated natural sand • Use of polymers to co-dispose clay/silt fractions with sand-size tailings • Multiple wheels in one bath to effect classification & dewatering in one simple device • PHOENIX has invested in a demonstration machine – up to ~40stph capacity
Enhanced washing with bucketwheel • Wash water passes counter-current to settling sand. • Can reduce entrained “fines” to very low levels. • Minimal wear & low energy demand. • Easy to understand & operate. • Simplicity! • Superior investment
Multi Product Wheels • Feed at one end, effluent a the other end • “Trajectory” classifying tank • Independent drives on 2 or more wheels • Classifying & dewatering in one unit • No support structure needed. • Simplicity! • Superior investment
