two-compartment cement mills, the ﬁrst compartment (for coarse grinding) has a step lining suitable for large grinding media. it protects the shell while ensuring optimum lifting of the mill charge. in the second compartment (and also in our one-compartment ﬁne-grinding cement mills) we use a corrugated lining designed to obtain the maximum
grinding media compartment 2: fine – grinding smaller size of grinding media • once the material has gone through the mill it is transported to a separator where it is divided into two fractions. • the finer fraction being the product and the coarser being the return to the mill for further grinding. closed circuit grinding

although it was developed nearly 50 years ago, bond‘s method is still useful for calculating necessary mill sizes and power consumption for ball and rod mills. this paper discusses the basic development of the bond method, the determination of the efficiency correction factors based on mill dimensions and feed characteristics, and the application of the results to designing grinding circuits.
recently, the vertical roller mill having great grinding performance is widely applied to the raw material grinding process. however, tube mill, which has about 30% poor grinding performance as power consumption, has been still used many existing cement plant. the improvement of this tube mill grinding system is highly expected. descriptions
raw mill grinding media dry chamber dry raw mills are the normal technology installed today, allowing minimization of energy consumption and co2 emissions. cement raw materials are mainly quarried, and so contain a certain amount of natural moisture. attempting to grind a wet material is unsuccessful because an intractable

the motion of grinding charge inside the mill. he also verified his approach with various plant data (napier-munn et. al., 1996). in this study, power draw of 14 multi-compartment cement grinding mills were calculated based on morrell’s approach. design and operational parameters for the mills were collected from operating plants.
grinding plant, separator speed and fresh feed are the main control parameters. the mpc controller frequently calculates new set points for the two parameters. the calculation is based on minimizing a so called 'cost-function' meaning minimum deviation from production targets and minimum changes of separator speed and fresh feed.
the capacity of grinding and drying of mill. the grindability affects the capacity of grinding, type of mill and roller pressure. the capacity of the mill is calculated using g k * d 2.51 where, g is capacity of the mill, k1 is roller mill coefficient and d is table diameter. 2. process control of vrm the conventional control system of vrm
addition of grinding balls watch raw mill sec daily and add grinding balls in right timing →10% energy saving expected ball diameter shrinks as time passes due to erosive effect. this leads to gradual increase of raw mill sec. filling level of grinding balls is also important in grinding efficiency. optimum level of filling should be maintained.
