If circulating load in the second ball mill is kept constant, any variation in the fresh feed will ultimately be reflected in the product particle size of Cyclone 2. Water addition to Cyclone 1 feed sump therefore not only controls the Cyclone 1 product particle size, but ultimately also Cyclone 2 product particle size. Size ratio control A new variable, called the particle size ratio was
