Hydrocyclone separators are used worldwide in the mining and mineral processing industries for classification, de-sliming and de-watering applications. The main purpose is to separate a stream of particles into different size fractions. However, there are also applications where a fine slime fraction requires removal or where the solids need to be dewatered as much as possible.
