Assess and optimise hydrocyclone performance to maximise your circuit performance.
Hydrocyclone Tests can be carried out by JKTech for cyclone characterisation, for benchmarking or to produce JKSimMet model parameters for mineral processing circuit simulation. The tests are conducted at the JKTech pilot plant using hydrocyclones of up to 380 mm in diameter.
The test cyclone is part of a closed system where overflow and underflow are collected in a common sump and recirculated. When the system is at steady state full stream samples are taken of the overflow and underflow streams. A full stream sample of cyclone feed is then taken with the cyclone out of the system. Flowrates, percent solids and particle sizings are determined for each stream.
Modifications to the standard test equipment can be made.
If simulation of an inclined cyclone is required it is best to conduct pilot testwork with the test cyclone inclined at the same angle as the proposed cyclone for simulation. Model parameters can be developed for the inclined cyclone in the same way as for a vertical unit. Vertical cyclone tests are usually also done on the same material.
Hydrocyclone Simulation Studies
The cyclone simulation study will use the results from the cyclone tests to develop
parameters for JKSimMet modelling of cyclones.
Using the results from the test work and/or surveys, cyclone models can be generated in JKSimMet. The simulation models can then be used for optimising cyclone operation or for designing cyclones.
For the smaller range of hydrocyclones, approximately 200 litres of slurry is needed for a suite of tests. According to the range of solid densities requested, this will require between 100 kg and 200 kg of dry material, depending on ore density. The larger hydrocyclones require a minimum of 800 litres of slurry supplied at the maximum possible percent solids. Alternatively, the slurry can be mixed up at JKTech. If necessary, coarse material can be crushed and then ground to a specified feed size by JKTech.
Download the Sample Transmission Forms, which include Sample Hazard Advice Form, and Quarantine Declaration Form. A completed Sample Hazard Advice Form must accompany every sample shipped to JKTech. In addition, a Quarantine Declaration Form must be completed for every sample originating from outside Australia.
