grinding system is applied if a production increase of 20 – 30 % is required. Energy saving of 15 % to 20 % is achieved depending on material to be ground. With semi-finish grinding an increase in production capacity depends essentially on the size of the high pressure grinding rolls. The finish grinding system is the most advanced grinding ...
Despite concerns faced by consumers about cement produced from a finish grinding roller press, the results of a performance test on concrete produced from combined-grinding cement and finished-grinding cement showed an equivalent water demand and a similar liquidity. The particle size distribution of products from both methods is also equivalent.

Roller presses grind raw materials and cement in a cost-efficient way. However, the highly dynamic process causes excessive stress on the bearings of the grinding rolls and the two drive trains, which ultimately fail and lead to unplanned stoppages. An online condition monitoring system that uses acceleration sensors can help avoid such stoppages.
