Embodiment Construction

[0053] The present application relates to a stability control system for a hydrocyclone which facilitates the separation of a liquid or semi-liquid material mixture into two phases of interest. The stability control system is arranged to allow detection of unstable operation of the hydrocyclone (with respect to the separation process) at an early stage and appropriate adjustments to return the hydrocyclone to stable operation.

[0054] refer to figure 1 A, shows a schematic cross-sectional view of a hydrocyclone 10 of conventional design comprising a main body 12 defining a chamber 13 therein. The chamber 13 comprises an inlet portion 14 and a conical separation portion 15 . The hydrocyclone also includes a feed inlet (not shown) for feeding the particle-laden mixture in the form of a particle slurry to the inlet portion 14 of the chamber 13 . An overflow outlet (hereinafter "upper outlet") 18 is centrally provided in the upper wall 20 of the chamber 13 to discharge the firs...

Abstract

A method of operating hydrocyclone comprising a separation chamber which in use is arranged to generate an internal air core for affecting a material separation process, comprises measuring both a vibrational parameter of the separation chamber and a stability parameter of the internal air core during operation of the hydrocyclone. The measurements are compared against predefined corresponding parameters which are indicative of a stable operation of the hydrocyclone and an operational parameter of the hydrocyclone is adjusted dependent on the comparison.

Description

technical field [0001] This application relates to stability control systems for hydrocyclones, and more particularly, but not exclusively, to stability control systems suitable for use in hydrocyclones in the minerals and chemical processing industries. Background technique [0002] Hydrocyclones are commonly used to separate suspended matter in a fluid into two discharge streams or "phases" of different densities. In the mining industry, for example, hydrocyclones are commonly used for separation purposes in slurries to separate the separated particles in a slurry into a heavier ("coarser") solid phase and a lighter ("finer" )Solid Phase. [0003] In normal "steady" operation, the slurry enters through the upper inlet of the inverted cone-shaped hydrocyclone separation chamber, where the heavier solids are expelled through the lower outlet and the lighter solids through the upper outlet and was expelled. However, the stability of the hydrocyclone can easily be disrupted...
