SikaGrind®-455 GNT

Grinding aid

SikaGrind®-455 GNT is a cost effective grinding aid for portland cement and other hydraulic cements. SikaGrind®-455 GNT is non chloride based grinding aid. SikaGrind®-455 GNT improves the efficiency of the grinding process and can reduce the energy for grinding clinker. SikaGrind®-455 GNT meets requirements of ASTM C 465.

SikaGrind®-455 GNT 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.
  • Less accumulation of material on grinding equipment (grinding balls and mill).
  • Reduce relative energy consumption per ton of cement.
  • Easier handling and minimized problems with “plugging” due to improved flow characteristics.
   SikaGrind®-455 GNT 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).
