effect of cone lifters on the discharge capacity of the mill

Effect of cone-lifters on the discharge capacity of the ...

Feb 01, 2007  Based on this result, it is postulated that the cone-lifters have some classifying effect on the material inside the mill. Thus the use of cone-lifters may be one possible way to enhance the proportion of mill charge exposed to the sweeping air, which would in turn enhance the discharge capacity of the mill fine product.
