Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    The Effects of Temperature on Cyclone Performance
    (University of Minnesota Duluth, 2006-03) Benner, Blair R
    The cyclone is widely used in the taconite industry to close grinding circuits. 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.
