The High Rate Thickener Solid Liquid Separation
Tailings from coal washing plants; Recycled water from aggregate washing . The Thickener Components. As mentioned previously most of the high-rate thickeners subassemblies are similar to those of conventional thickeners except for lifting devices that are not available on all units due to design restrictions.

High Rate Thickeners High rate thickeners are designed specifically to maximise the flocculation efficiency of flocculants. They differ from conventional thickeners in feed well design, size and control. Unlike conventional thickeners, high rate thickeners must use flocculants. The basic design of a high rate thickener is below.

Why high-rate thickeners are now preferred by the gold
LETTER FROM AUSTRALIA Why high-rate thickeners are now preferred by the gold industry by Allan Waters BHP Research & New Technology, Shortland, NSW High-rate thickeners have shown themselves to be more cost-effective than conventional thickeners in recovering water and cyanide in gold mines, and other mineral processing plants.
Pulp, paste and putty: thickeners and flocculants for high
Care needs to be taken with the nomenclature of conventional or high rate thickeners. The critical difference is the use of feed dilution and flocculation in high rate thickeners over conventional thickeners; however, the high rate thickener has become so ubiquitous in the mining industry it has become the ‘conventional’ choice.
Conventional Thickeners Solid Liquid Separation
Conventional Thickeners are generally incorporated in heavy duty applications when the underflow density is high and substantial torques are required to convey the settled solids from the periphery to the central outlet for pumping away.
HiFlo High Rate Paste Thickeners WesTech Engineering, Inc.
