What pump should you use for Thickener Underflow?
Thickener tanks are a time and space-saving way of de-watering slurry, removing the waste silt and allowing the water to be recycled.
In the quarry environment, thickener tanks are used at the end of the wash plant process, after the cyclones.
A lagoon on site can serve the same purpose, but these take up space, require maintenance, and are much slower as it takes a long time for the silt to settle out.
Thickener tanks are becoming more and more popular and are now regularly seen on inner-city sites, wharfs, quarries and on sites that are no longer able to use their lagoons.
