    Closed circuit grinding vs open circuit grinding

    An increase in the diameter of a mill gives greater economy in two ways in the first place, the balls do more effective work in a large than in a small mill, because, falling from a greater height, they shatter the pieces of ore with greater force in the second place, the ratio of the deadweight of the mill to the weight of the ball charge
