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.
- 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.
- Reduced quantity of “over-milled” particles in the cement granulometry;
- Easier discharge of the silos;
- Increased strengths;
- Economic cement design with clinker replacements.
