The power consumption of raw material vertical mill system is /t lower than ball mill, that is to say: in one year, a 5000TPD cement plant can save energy in clinker grinding system: /t * 5000t/d * 300d=14,550,000 kWh, that means the cement plant clinker grinding system can save 14,550,000 kWh electricity one year.
The grinding of the finished cement consumes approximately one third of the total electrical energy of a cement plant. Vertical roller mills (VRM) have a higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments led to the increased share of VRM for the grinding of finished cement.
