What Affects The Mineral Processing Cyclone Cut Size

What Affects The Mineral Processing Cyclone Cut Size

As such, the cyclone diameter selected for a given application is associated with the desired size separation. In mineral applications. it is generally stated that a certain size cut is desired which would imply that the majority i.e., 95 of underflow solids has a size greater than the target cut point and the overflow has a majority less than the desired cut point.

  • Partition Curve An Overview Sciencedirect Topics

    The commonest approach to describe the efficiency of a cyclone is through its partition or performance curve in which the mass fraction of each particle size in the feed that reports to the underflow is related to the particle size itself, as indicated in Figure 3. The sharpness of the cut is indicated by the slope of the central portion of the graph, and the larger this slope the closer to the vertical, the more efficient the

  • Cfd Modelling Of Hydrocycloneprediction Of Cut Size

    Jan 06, 2005 The cut size of the hydrocyclone, operated at very low pulp density, has been predicted using discrete phase modeling technique. The studies revealed that with an increase in feed flow rate and decrease in spigot diameter the cyclone sharpness of separation improves. These predictions were found similar in line with the experimental observations.

    Multiple, smaller Hydrocyclones operating at the same pressure as one large Hydrocyclone will have a finer cut point. Without going too deep into the math, the two forces that have the most impact on the cut point are centrifuge CF and drag DF. With the CF directly affected by the radius of the Hydrocyclone, the cut point changes.

Although slime is deleterious to metallurgical performance in gravity concentration devices, its effects are an inverse function of the gravitational field applied. In gold grinding circuits much of the free gold can lie in the finer size fractions and is amenable to concentration using
