6 Factors Affecting Hydrocyclone Efficiency

2020-5-14  If particle size of the ore feed is fine and the feed pressure is high, the ratio of the feeding port to the diameter of the hydrocyclone is usually maintained at 0.14 to 0.16. In addition, the shape of the feed port (often rectangular) and the feeding method (tangent or involute) also have some effect on the classification efficiency.

Hydrocyclone Separator Multotec

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.
