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.Hydrocyclone separators are used worldwide in the mining and mineral processing industries for classification, de-sliming and de-watering applications.

According to the particle tracking inside the hydrocyclone, the erosion location and its density rate on the wall surfaces were predicted with the Grant-Tabakoff erosion model and presented in Fig. 16 as an ...Aug 06, 2015 Hydrocyclone Working Principle. The centre of this spiral is called the VORTEX. The purpose of the apex is to cause internal pressure for the cyclone and to create a vortex that extends all of the way to the top of the cyclone. In all hydrocyclones there are two outlets, one for the coarse material, this is the APEX, and the other for the fine ...Jan 12, 2021 The classification process. A hydrocyclone is designed to separate particles of different sizes, utilising centrifugal acceleration in a swirling flow field. Centrifugal acceleration is made possible through tangentially introduced velocity, which is the motion of an object moving along the edge of a circular path or in the case of a hydrocyclone, along the outside wall of the equipment.
