Published on: July 11, 2023 by Naresh Bhakar. Size Separation involves the separation of a mixture containing particles of various sizes into two or more portions. This can be done through the use of screening surfaces or by shifting the mixture. It is also commonly known as sieving, sifting, or screening. The technique of size separation is ...

Advantages of using steam separators. 1. Provides quality steam. The steam separators are installed on the boiler output to ensure that the steam provided to the turbine or point of application is dry. As we have seen, steam separators remove moisture from the steam and this clearly tells us that the steam will be dry.

A comprehensive numerical analysis of the fluid flow and dilute particulate flow in the LD9 spiral separator is presented in this work. The air–water flow field on a coal spiral is simulated using the volume of fluid (VOF) coupled with RANS turbulence models. Water depth and flow field predictions by RSM show close agreement with experiments.

Working Principle. Spiral Separators, which are also called Spiral Concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium. The heavy frictional forces slow their velocity. As a result, faster particles higher up in the flow.
