  200951 · For coarse particle grinding in tumbling mills Eq. (1) is written as: (4) W a = K 1 M ia 4 x 2 f (x 2)-x 1 f (x 1) where. K 1 = 1.0 for all circuits that do not contain a recycle pebble crusher and 0.95 where circuits do have a pebble crusher.x 1 = P 80 in μm of the product of the last stage of crushing before grinding. x 2 = 750 μm.
