SikaGrind®-455 GNT

SikaGrind-455GNT is a cost-effective grinding aid for Portland cement and other hydraulic cements. SikaGrind-455GNT improves the efficiency of the grinding process and can reduce the energy needed for grinding clinker.

SikaGrind-455GNT provides the following advantages in the cement production:

  • Increased the production rate (tons per hour).
  • Improved the grinding efficiency.
  • Improved separator efficiency due to improved dispersion.
  • Faster achievement of the desired cement fineness.
  • Reduced particle fraction > 32μ of the ground cement.
  • Reduced re-agglomeration of the cement particles.


SikaGrind-455GNT gives the following advantages to the finished cement:

  • Reduced handling costs especially on pneumatic conveying systems.
  • Easier discharge of the silos.
  • Improved self-levelling of the cement in the silo.
  • Improved cement granulometry (reduced quantity of “over-milled” particles).
