MasterCem GA 1130 - Cement additive engineered for reduction of unit grinding energy and increase of mill throughput
How does it work?
MasterCem GA 1130 is a liquid, ready-to-use Grinding Aid
for cement. It neutralizes the agglomeration forces between fractured crystalline cement particles that are produced during the milling process. The resulting dispersion
effect improves grinding and separation efficiency, thus,
promoting the development of fineness and cement powder flowability.
These benefits can be used for lowering unit grinding
energy cost and for increasing mill throughput. Typical
grinding efficiency improvement is in the range of 10-25%
vs. plain control. However, product performance is dependent on grinding equipment characteristics, process
conditions, raw material properties and cement type. To
best benefit from cement additives, mill and separator
process parameters may need to be adapted.
MasterCem GA 1130 improves the flow characteristics of
cement with positive impact on cement conveyance and
reduction of pack-set in storage silos.
What is it used for?
MasterCem GA 1130 is developed for application in the
cement grinding process in:
- Ball mills (closed and open circuits)
- Vertical mills
- Other cement grinding systems
What are the benefits?
MasterCem GA 1130 offers the following benefits to cement producers:
- Cost reduction due to lower unit grinding energy
(kWh/t) and decreased specific maintenance cost. Use
of low-cost energy tariffs and transfer of production to
more efficient mills.
- Capacity extension due to higher mill throughput.
Flexibility to satisfy peak market demands. Postponing
or avoidance of investments for grinding capacity increase.
- Improved cement handling due to faster cement
conveyance through the plant and in the distribution
logistics. Reduction of plant stops and optimized storage in silos.
