cement ginding aids for cement plant

Description
HW-CGA Cement Grinding Aids offer all the benefits of traditional grinding aids, such as increased grinding
efficiency and cement flowability. In addition, they offer a unique ability to improve cement strengths which might
otherwise be deficient due to mechanical, physical or chemical shortcomings. Advantages include either
reduced cost of production or increased cement strengths.
Primary Benefit
The HW-CGA series of Cement Grinding Aid consists of tailor-made formulations to optimize performance and
meet specific requirements at each plant. The use of HW-CGA allows the cement producer to reduce fineness
and achieve lower unit power costs without sacrificing strength. Compared with conventional grinding aids,HW-CGA offers unit power savings of *0% ~ *5% with no loss of strength. And the resulting production increases
can greatly benefit plants operating at or near their grinding capacity.

Advantages
The chemical action of HW-CGA cement griding aid decreases the interparticleattraction between cement grains
and increases the rate of hydration of cements.
The key advantages of HW-CGA cement grinding aid include:
1 Increased grinding efficiency with resulting increased mill output, higher cement fineness and/or reduced unit
power and grinding costs.
2 Increased workability (flow) of cement mortars and concretes.
3 Increased cement flowability and reduced pack set or silo set of cements resulting in lower handling costs
and reduced waste.
4 Increased early and long-term compressive strengths for production of better quality cements.
5 Reduced cost of cement production through reduced unit grinding costs and through replacement of clinker
with reactive additions such as pozzolans, blast furnace slag and fly ash or with fillers such as limestone.
HW-CGA cement grinding aids are most effective in enhancing compressive strengths of blended cements
increasing to 5~8% limestone filler.
When cement particle size is not reduced, the addition of HW-CGA improves both early and long-term strength
and produces higher quality cement. Strength increases ranging from 5% to *0% have been demonstrated
during plant trials.
Packaging
HW-CGA is supplied in **0 L drums. HW-CGA may also be supplied in bulk in certain locations. It contains no
flammable materials.
Storage
Protect from freezing. Once frozen, the product should be thawed out slowly and re-mixed thoroughly prior to
use. Shelf life is minimum *2months in manufacturer's containers.
