Optimum Grinding

The cement industry uses a wide range of different systems in raw material, coal, and cement grinding. While new plants mainly focus on highly energy‑efficient systems, using roller comminution systems like vertical roller mills (VRMs) and high pressure grinding units (roller presses), less efficient ball mills and combined grinding systems (pre-grinder plus ball mill) are still widely used. Which option to install depends on the local cement market, the product portfolio and raw materials, as well as the relevant operational skills available to maintain such systems.The industry is facing high volumes in every global market and cement pricing is driving producers to
optimise their systems to peak performance. Rising electrical energy costs have created a trend to force plants to reduce their production costs by system and wear part strategy optimisation.
