SikaGrind®-455 is a high-performance grinding aid for Portland cement and other hydraulic cements. SikaGrind®-455 is a non-chloride based grinding aid developped to improve the efficiency of the grinding process. Its use can reduce the energy needed for grinding clinker and significantly increase mill through-p

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

  • Increased the production rate (tons per hour)
  • Improved the grinding efficiency
  • Higher 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)
  • Cost savings due to a lower energy consumption per ton of cement
  • Easier handling and minimized problems with “plugging” due to improved flow characteristics

SikaGrind®-455 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 silos
  • Improved cement granulometry (reduced quantity of “over-milled” particles
