In intermediate grinding to approximately 75 μ m, the Bond equation (Eq. [ 1 ]) is used to relate feed size, product size, and mechanical energy applied. Below 75 μ m, correction factors can be applied to extend its range of validity. [ 4]
Step by step evaluating the each equation would finally end up with the Eq. (9), which provided the proportion of the specific energy efficiencies for the conditions (for bead size and 4 mm) (See Eq. (9) ). (9) S E e 2, 5 S E e ( 4) = E cb ( 4) E cb ( ) = = 3. Results and discussion

Efficiency = Wio/Wi x 100 When (Wio/Wi)x100 is less than 100 this indicates the circuit, based upon this comparison, is operating efficiently. When it is greater than 100 this indicates the circuit is operating inefficiently. A large difference, either low or high, could indicate that the two work indicies are not on the same basis.
mining ball mill full image x . Ball Mills . 8 3 2 2 Ball mills The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 11 5 times the shell diameter Figure 8 11 The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 2040 water by weight .
The coarser ash particles, known as bottom ash or slag, fall to the bottom of the combustion chamber. The lighter, finer ash particles, known as fly ash, remain suspended in the flue gas. The disposal of fly ash presents a challenge because of the staggering amount produced by coalfired power plants and because of the heavy metals ...
