A wet overflow mill of dimensions 3.05 mx3.05 m was charged with Nickel ore of density 4.2 having a F80 value of 2.2 mm. The mass of balls charged for grinding was 32t with a density of 7.8t/m3. The mill was rotated at 18rpm. The Bond's work index for Nickel ore is 11.88kWh/t and bed porosity inside ball mill is 40%. Calculate: (a) The fraction ...
Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …
ABC closed circuit, Autogenous-Ball-Mill-Crusher. Another similar technique is the ABC open circuit where the crusher product feeds the ball mill rather than the autogenous mill. Crusher product is typical feed to a ball mill using large diameter balls but not much grinding of 20-25 mm ore can be accomplished in an autogenous mill.
