The work demonstrates the application of the population balance model in the optimization of a full-scale ball mil circuit grinding pellet fines with the ...

These forces responsible for the agglomeration of iron ore fines are generated in the balling disc due the rotational movement in the balling disc. When the solid particles come in contact with water, the ore surface is wetted and coated with water film. Because of the surface tension of the water film, liquid bridges are formed.
