SikaGrind®-180 MY

Grinding aid for the production of cement

SikaGrind®-180 MY is a liquid cement grinding aid with performance enhancing properties. SikaGrind®-180 MY has been specifically designed to increase the output of cement grinding plants and obtain improved strength development for cements.

SikaGrind®-180 MY is a dispersant with the following characteristics:
  • Neutralisation of electrical charges on the surface of the cement particles
  • Separation of the cement particles
  SikaGrind®-180 MY provides the following advantages in the cement production:
  • 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
  • Improved powder flow characteristics
SikaGrind®-180 MY gives the following advantages to the finished cement:
  • Reduced quantity of “over-milled” particles in the cement granulometry
  • Easier discharge of the silos
  • Increased early strengths
  • Economic cement design with clinker replacements

Application

Application Information

Compatibility

Cements treated with SikaGrind®-180 MY are compatible in concretes produced with all commercial admixtures including air entrainers, water reducers, retarders and superplasticizers. The performance of concrete admixtures is not adversely affected by the use of SikaGrind®-180 MY.

DISPENSING

SikaGrind®-180 MY is added onto the clinker feed shortly before the mill entrance or directly into the grinding mill (first or second compartment). Suitable dosage pumps with adjustable flow rates shall be used for accurate dosing.

Note: Periodically, the end of the additive tube/hose shall be checked to ensure that it is not blocked!
Consumption

Recommended dosage

Typical dosage rates of SikaGrind®-180 MY is between 0.5–2.0 kg per tonne of cement (0.05–0.20 % of total weight = cement clinker + additions). The optimum dosage to achieve the desired characteristics shall be determined in Plant trials. Influencing factors are e.g. the properties of clinker source, type of cement and other plant variables.

For consistent results, SikaGrind®-180 MY must be accurately dispensed.
