For a given cyclone geometry, the main operating variables are flowrate, feed size distribution, and slurry rheology. Generally the slurry density (percent solids) is used to approximate the slurry rheology. However, it is known that slurry temperature can also affect the rheology. The purpose of this test program was to determine the effect of temperature on cyclone performance as measured by cyclone weight split and cut size, D50• Two samples of cyclone feed were obtained from Evtac (now Utac). The samples were taken about 6 months apart.enCyclone geometryFlowrateFeed size distributionSlurry rheologySlurry temperatureHydrocycloneTaconite industryEvtacNatural Resources Research InstituteUniversity of Minnesota DuluthTechnical Report
