SikaGrind® GA 1130

(former MCem GA 1130)

Cement additive engineered for reduction of unit grinding energy and increase of mill                                                                                                                                                                                                 throughput

SikaGrind® 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. Grinding efficiency is improved vs. plain control.
SikaGrind® GA 1130 improves the flow characteristics of cement with positive impact on cement conveyance and reduction of pack-set in storage silos.

SikaGrind® GA 1130 offers the following benefits to cement producers :
  • Cost reduction due to lower unit grinding energy (kWh/t) and decreased specific maintenance cost.
  • Capacity extension due to higher mill throughput.
  • 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.

APPLICATION INSTRUCTIONS

SikaGrind® GA 1130 can be metered onto the mill feeders or injected into the mill. The recommended dosage rate is between 200 - 600 g per ton of cement. Other dosages may be required in specific situations. The optimum dosage should be evaluated in plant trials. For further information please consult Sika Technical Service Department.
Calibrated dosing equipment with an adjustable flow rate and appropriate dosage range is recommended to obtain the maximum performance of the product.
