cements ground in the vertical roller mill fulfil the quality Loesche

on a century or more, ball mill systems were used for all three grinding stages, but the development of more energy efficient vertical roller mills (VRMs) led to their replacement. Initially, this focused on grinding coal and the cement raw materials, with the adoption of vertical roller mills for cement product grinding – with its 

CEMENT SikaGrind® FOR VERTICAL ROLLER MILLS

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 clearly 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
