SikaGrind®-180 MY NG

Strength enhancing grinding aid for the production of cement

SikaGrind®-180 MY is a liquid cement grinding aid with
performance enhancing properties 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 and 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 and easier discharge of the silos
▪
Increased early strengths and economic cement
design with clinker replacements
▪

System 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.

Application

Application Information

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).
Prior plant trials are necessary to determine optimum dossage because
of variables such as clincker properties, cement type, and others.
