SikaGrind®-425

SikaGrind-425 is a cost-effective grinding aid for Portland cement and other hydraulic cements. SikaGrind-425 is non chloride based grinding aid. SikaGrind-425 improves the efficiency of the grinding process and can reduce the energy needed for grinding clinker.

SikaGrind-425 provides the following advantages in the cement production:

  • Increased the production rate (tons per hour).
  • Increased mechanical strength at 28 days.
  • 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-425 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).
