WesTech HiFlo™ high-rate thickeners are used in many types of process circuits to separate liquids and solids at very high rates. They are highly effective in coal refuse thickening, gold recovery, CCD circuits, copper leaching, molybdenum processing and other mining and chemical flowsheets. Separation is effected rapidly because of the system hydraulics, which can be in excess of twenty times the hydraulics of conventional thickeners.
As a result of the innovative design and associated hydraulic efficiency, the plant area for the HiFlo high-rate thickener is greatly reduced, even making indoor installations practical. The smaller equipment size substantially reduces capital, installation costs, and plant space when compared with conventional thickening units sized for the same production rates.
WesTech’s technical staff can assist in testing process practicality, equipment sizing, and aid in solving other problems encountered in today’s sophisticated and automated flowsheets. Pilot or laboratory size equipment is available for testing or purchase. WesTech’s design provides for deaeration of the thickener feed prior to flow into the feedwell. Proper level of the flocculation can be carefully controlled. Feedwell design enhances the separation and pulp bed interface sensors are utilized for optimum performance. WesTech drives with lifting capability and high torque capacity contribute to the machine’s superior performance.
Flocculation, pulp level, underflow density, overflow quality, torque, and rake lift position can all be easily managed. HiFlo sensor outputs are used in many installations by distributed control systems to integrate thickener control with other plant functions, resulting in improved clarification of overflow and high solids concentration of underflow.
