basic calculation cyclone

The nomographs by Zanker can be used to make a preliminary estimate of the size of cyclone needed. The specialist manufacturers of hydrocyclone equipment should be consulted to determine the best arrangements and design for a particular application. Zanker’s method is outlined below and illustrated in the Example below and based on an empirical equation by Bradley (1960):

Where:

d50 = the particle diameter for which the cyclone is 50 per cent efficient, Micron

Dc = diameter of the cyclone chamber, cm,

u = liquid viscosity, centipoise (mN s/m2),

L = feed flow rate, l/min,

pD = density of the liquid, g/cm3,

ps = density of the solid, g/cm3.

                                           Determination of d50 from the desired particle separation

furthermore, we can see the different variable that determines cyclone such as viscosity, density, flow rate, diameter inside the cyclone.

after define Dc, we can find another dimension base on the below picture.
