Principle of Operation of Hydrocyclone

A hydrocyclone (often referred to in the shortened form cyclone) is a device to classify, separate or sort particles in a liquid suspension. Hydrocyclones are preferred units for sizing or desliming large slurry volumes cheaply and because they occupy very little floor space or headroom.

Air core formation in the hydrocyclone ScienceDirect

1. Introduction. Air is the often the neglected third phase of the 3phase flow in the hydrocyclone. The air core at the center of the hydrocyclone is an unavoidable phenomenon in the rotational flow field which does not directly influence the classification process in the apparatus.

HYDROCYCLONES Thermopedia

The hydrocyclone is a simple piece of equipment that uses fluid pressure to generate centrifugal force and a flow pattern which can separate particles or droplets from a liquid medium. These particles or droplets must have a sufficiently different density relative to the medium in order to achieve separation.

theory,applications,and practical operation of hydrocyclones?

Apr 03, 20060183;32;hydrocyclone represents a sensitive process variable for separation in the hydrocyclone. On this basis, a new control concept for a hydrocyclone battery has been developed. As the solids concentration in. the feed increases, the combined overflow of all the hydrocyclones in the battery is throttled. At the. same time, the feed pump speed is increased.

Hydrocyclone Working Principle

PurposeThe third type of classification used in mining is the Hydrocyclone, commonly called a Cyclone. Unlike the others it has no moving parts and is worked in conjunction of another piece of equipment, a pump. To understand the Hydrocyclone Working Principle we must first know its components. Beginning at the top, there is the OVERFLOW DISCHARGE.

VWS STREAMLINER Deoiling Hydrocyclones

The purpose of the VWS STREAMLINER deoiling hydrocyclone is to separate free oil from produced water prior to discharge or injection. Usually situated after the primary separators, deoiling hydrocyclones are normally regarded as the first stage in the treatment process.

Hydrocyclone

A hydrocyclone (often referred to by the shortened form cyclone) is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance.This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles.

Tutorial Model Flow in a Hydrocyclone

Cyclones are used in a variety of applications ranging from the mining industry to vacuum cleaners. The flow in a cyclone is characterized by a very strong swirl, which makes it difficult to simulate. In this tutorial example, the v2f turbulence model is used to simulate the flow in a hydrocyclone.
