The influence of hydrocyclone diameter on reduced

1974. 5. 1.  It has been found (Rao, 1966) that for a given operation the reduced-efficiency curve is constant for wide changes in flow rate and solids content of the pulp, and diameter of the vortex finder and spigot of the hydrocyclone, but the effect on the reduced- efficiency curve of maintaining geometrical similarity of cyclones and changing the cyclone diameter is not known.

Fundamentals on the spigot capacity of dense medium cyclones

2012. 4. 26.  The capacity of dense medium cyclones is often restricted by the solids-carrying capacity of the underflow, referred to as spigot capacity. Cyclone manufacturers normally recommend the spigot capacity for a cyclone of a particular size; however, it is not clear how these capacities are determined and whether they can be increased. In the literature,

Particle Size Effects on Hydro-Cyclone Performance

Finally, the effect of particle size on hydrocyclone performance has been studied. It was found that the grade efficiency and number of particle that exit from underflow of the hydrocyclone is increased when bigger particles is used. A series of experiments has been carried out in a laboratory with a hydrocyclone.

AMIT 145: Lesson 2 Classifying Cyclones Mining Mill

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.

Larger vortex finders or inlet areaswould increase the capacity, whereassmaller vortex finders or inlet areas woulddecrease the capacity. The shaded area inFigure 9 corresponding to each standardcyclone gives the approximate range ofcapacity for each cyclone.

The Effect of Rheology on the Performance of Hydrocyclones

Abstract. The experimental work has been carried out on range of spigot diameters and two hydrocyclone sizes. The slurries used were mixtures of ball clay and silica which have been used as models for industrial slurries. Variations in the rheological properties were effected by varying the concentration of each of the components and with the use of viscosity modifiers.
