Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.

The raw mill is not limited by drying capacity. The residue on 2mm/4mm before partition wall. Maintaining a proper preparation of the material before passing to the next compartment is the highest objective. Cement mill: target is to reach < 5% residue on the 2mm sieve. Raw mill: target is to reach < 5% residue on the 4mm sieve.
By using casting steel ball you can meet the major benefits such as high performance and low cost so most of the company wish to prefer such ball for the major users in the plant. Apart from that it has wide range applications but especially in the cement industry as the representative of dry grinding field. The casting steel ball has …
These interactions enable a range of processes. Depending on the particular product and task at hand, these could include size reduction, dispersion, or deagglomeration processes, as well as emulsification, cell disruption, or homogenization. As the tools of the ball mill, the media have a crucial impact on the outcome of the dispersion or wet grinding process.
The mill produces optimum-quality, high-resistance cement with a lower Blaine, and enables an exceptionally high cement/clinker ratio. The FCB Horomill® helps cement producers reach sustainability goals through: The lowest energy consumption on the market (30-65% energy savings compared to ball mills, and 10-20% compared to vertical roller …
