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.
