    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 is typically half that of a ball mill. However, the narrowness of the particle size distribution of the cement is problematic, and the process has yet to receive wide acceptance.

  • Separators in the cement industry

    * Suppliers propose generally a version for raw and cement mill circuits where the gas and the material are going out together of the mill and enter from the bottom of the separator. * Some suppliers propose also special versions for circuits with pre-grinding systems (Roller Press).

  • Cement Seperator for Cement Grinding System

    Application: In cement industry production, in order to improve the efficiency of the grinding system and reduce the energy consumption of the product, a circulating grinding system is now widely used. As an important part of the system, the advanced performance of the classifier directly affects the efficiency of the system.

    Optimization of Cement Grinding Operation in Ball Mills. Internal inspection of the mill can reveal a lot of important and vital information about the performance of the grinding system such as the separator’s behavior, influence of grinding media and the mill ventilation.

  • Separators in the cement industry

    To avoid dust emissions, the separator system must be underpressure (±50 mmH2O). In order to maintain that target, an additional filter must be installed in case of cyclones design. The additional air flow corresponds to ±10% of the separator air flow.
