All except soft materials are first crushed, often in two stages, and then ground, usually in a rotating, cylindrical ball, or tube mills containing a charge of steel grinding balls. This grinding is done wet or dry, depending on the process in use, but for dry grinding the raw materials first may need to be dried in cylindrical, rotary

Any action aiming at reducing the consumption and cost of grinding media is welcome. To achieve this goal, it is necessary to understand the wear mechanisms that take place in grinding process and to consider the details of such process like the interaction between mineral slurry and grinding media.

This work deals with the energy consumption in cement grinding section and an attempt to improve the performance of ball mill in Cement consumes 83% of total energy which is used in the production. Energy has influence of 20% to 40% on cement cost. Main energy consuming process is the grinding of cement and.

These have been used for many years for the less exacting raw-milling process, but recently roller mills, in combination with high-efficiency separators, have been used for cement grinding. The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient. Energy consumption

Various degrees of wet processing exist, e.g. semi-wet (moisture content of 17-22%) to reduce the fuels consumption in the kiln. Clinker plants with wet kilns use more water per ton of cement than plants with dry kilns.

In Germany, an excess figure of 10 % is generally considered for dry grinding in contrast to the energy consumption for wet grinding [69b]. The increased metal wear of grinding media and mill liners for wet grinding equalizes the additional energy costs of the dry grinding procedure. When dry grinding cement raw material,
