### SEPARATOR'S EFFICIENCY AND CIRCULATING LOAD | VDChari

Vf is normally a constant for all the dimensions of particles; but calculations being based on sieving, we will use an average Vf . From Vf, we define Vr: Vr = 1 – Vf(average) C = 100 /Vf(average) C is called the circulating load of the separator. It can also calculated by. C = F/P or (p – r) /(f – r)
