Second: Because limestone and related materials have a high 'lubricity' value compared to clinker, these materials exhibit a 'fluxing' effect in the finish mills, further reducing the . specific milling energy. required for the resulting discharge of the finish mills (the 'finished-cement') to meet QC specifications.
taken care of by the use of grinding aids and also by optimizing the cement mill technology. The latter will not be considered in detail in this state of the art report. Reducing energy consumption is therefore another main driving force in the field of cement mill technology.
Vertical roller mills (VRM) can replace ball mills or tube mills used for preparing coal. Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding. According to MIIT, grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder, as compared to 100 g/ton of coal powder in a ball mill.
Schneider et al. [11] [12][13] improved the energy utilizing efficiency of the raw mills to reduce the energy consumption in cement plants. Besides, some other researchers studied the energy ...
ABB drives reduce energy consumption and improve productivity of cement plant Indian cement industry The Indian cement industry has experienced a continuous growth since its deregulation in the 1980s. India is now the world's second largest cement producing country after China. The industry is characterized by a high degree of fragmenta-
Traditionally, ball mills are used in cement industry for raw material, fuel and product grinding. Ball mills use an established technology and offer certain advantages.
