In 2011, the world cement production was approximately Bt/ Bt (clinker) (, Survey. 2014 ), requiring more than Bt of limestone for the manufacture of clinker ( Schneider et al., 2011). However, large material flows solely related to cement production have a significant impact on society and the environment.
The formula for calculating critical mill of speed: N c = / √ (D d) Where: N c = Critical Speed of Mill. D = Mill Diameter. d = Diameter of Balls. Let's solve an example; Find the critical speed of mill when the mill diameter is 12 and the diameter of balls is 6. This implies that;

The original ball load in the mill was 6614 lb. (3000 kg.) and the load at the end of the 694 hr. was 6338 lb. ( kg.). During this time, 590 lb. ( kg.) of balls less than 3 in. ( mm.) in diameter were discarded from the mill. The screen analysis of the ball charge at the end of the operation is shown in Table 20.

Raw mills usually operate at 7274% critical speed and cement mills at 7476%. Calculation of the Critical Mill Speed: G: weight of a grinding ball in kg. w: Angular velocity of the mill tube in radial/second. w = 2** (n/60) Di: inside mill diameter in meter (effective mill diameter). n: Revolution per minute in rpm.
Figure 3a and 3b gives the results of the computer calculation. The mill power at the pinionshaft for a 30% volume charge is the sum of: Figures 3a 3b give the power for an autogenous mill. Figures 4a and 4b are for the same size mill with a ball charge of 6% of mill volume (290 lbs. per cubic foot).
In terms of this concept, the energy efficiency of the tumbling mill is as low as 1%, or less. For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is % of the total energy supplied to the mill setup.
