You may calculate the cyclones dust collection efficiency by theoretical way.

Thanks Raj and Harald for the Answers. 

sir , for this cyclone efficiency calculation ,  differencial pressure of cyclone is important or not?  

if yes ,  which points to be measured for the Dp in cyclone,  and if any calculation is there ?

pl  send me.

thanks in advance

I am having calculation sheet for dust load calculation.You will also get cyclone efficiency through CFD analysis.
