SikaGrind®-728 VN

EFFICIENT GRINDING AID FOR THE PRODUCTION OF CEMENT

SikaGrind®-728 VN is a chloride-free liquid cement grinding aid with performance enhancing properties.
SikaGrind®-728 VN has been specifically designed to increase the output of cement grinding plants and obtain improved strength development for cements with high amount of clinker replacements

SikaGrind®-728 VN is a dispersant with the following characteristics:
  • Neutralisation of electrical charges on the surface of the cement particles;
  • Separation of the cement particles.
  SikaGrind®-728 VN provides the following advantages in the cement production:
  • Enhanced grinding properties of the cement mill due to less accumulation of material on grinding balls and mill-liners;
  • Higher separator efficiency due to improved cement particle dispersion;
  • Reduced relative power consumption per ton of cement due to increased output of the grinding system (tons per hour);
  • Easier achievement of the desired cement fineness (Blaine, particle fraction > 32μm, granulometry) due to reduced re-agglomeration of the sufficiently ground cement particles;
  • Minimized problems with “plugging” due to improved powder flow characteristics.
SikaGrind®-728 VN gives the following advantages to the finished cement:
  • Reduced quantity of “over-milled” particles in the cement granulometry;
  • Easier discharge of the silos;
  • Increased strengths;
  • Economic cement design with clinker replacements.
