Running continuously since its installation in 1988, the control system utilises industrial IBM 80286 personal computers to regulate a grinding circuit comprising twelve 16.5 ft x 24 ft single stage ball mills in closed Circuit with inclined hydrocyclones
 applied the numerical simulation method that simulated the efficiency for particles with low concentration in a hydrocyclone
. The result showed the modified k-[epsilon] model produces results in good agreement with experimental data.
Managing Director, Greg Cochran said the testwork demonstrates that the TRS low grade deposit can be beneficiated, in an economical and chemical free process, to produce a low carbonate, uranium rich concentrate with the use of hydrocyclones
; effectively upgrading the material to suitable feedstock for the proposed Omahola Metallurgical Plant.
--ensuring permanent work of hydrocyclones
during separation of sand and overflow;
Experimental testing of a hydrocyclone
in the separation factory of the Estonia mine demonstrated the possibilities to separate the slime whose heating value is low, and add to the production about 1% of material with high heating value .
The MCRRS vehicle uses hydrocyclone
technology; which does not require soap; uses only pressurized water; and reclaims and recycles the spent cleaning water.
The GEM (gas, energy, mixing) System is a hybrid centrifugal--dissolved air flotation (DAF) process that utilizes extremely energetic hydrocyclone
mixing to nucleate bubbles and forms flocs simultaneously.
Other topics include inflections in hydrocyclone
efficiency curves, the influence of slurry theology on stirred media milling of limestone, the selection of mill liners, the gearless mill drive, and ball mill circuit models for improving plant performance.
In these experiments, the hydrodynamic characteristics of individual wood fibers were measured under conditions simulating those in a real hydrocyclone
are used to group fibers by their characteristics to improve sheet formation.
