CEMENT MILLING AND SEPARATION EFFICIENCY M. Magistri1, P. D''Arcangelo1, R usually carried out in ball or vertical roller mills. Efficiency of grinding (in terms of energy actually used to increase cement fineness over total energy) is usually very low and reported to be in the range 1030%. Due to increasing interest in energy savings and high fineness cement production, it is mandatory

· 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.

calculated and gives a value of the load ''expansion''. (Figure 4.) It is well known that ball milling efficiency varies during the lifetime of the shell liner. For instance, the mill performance could become worse or better by putting in a new shell liner. Data from pilot plant test work illustrates the influence of the shell lifting effect on the grind for a primary grinding duty

consisting of a tube ball mill and a high efficiency separator was introduced through the matrices of grinding and classification. The grinding matrix was calculated using the selection and breakage functions, whereas the classification matrix was defined from the Tromp curve of the separator. The results of field experiments carried out at a pilot cement plant were used to identify the model

For many decades the twocompartment ball mill in closed circuit with a highefficiency separator has been the mill of choice. In the last decade vertical mills have taken an increasing share of the cement milling market, not least because the specific power consumption of vertical mills is about 30% less than that of ball mills and for finely ground cement less still. The vertical mill has a

· Due to limitation of the mill''s rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (58 mm range) improves grinding energy efficiency up to 50% using stirred mills. For specialized types of cement, which are finer than Portland, this figure would be even higher
