The COSMA material analyser now accurately measures fly ash and slag simultaneously in real time. Through advances in x-ray technology the COSMA online powder analyser now measures fly ash and slag contents up to 70% in blended cement.

When used in a cement mill application, COSMA provides a full analysis of the cement, ie C3S, C2S, C3A, C4AF, CaO, CaSO4.2H2O, CaSO4. ½H2O, CaSO4, K2SO4, Na2SO4, CaCO3, MgO, flyash and slag. The results are immediately available in the control room and are used to control the feed rate of gypsum, limestone, flyash and slag to the cement mill. Its role has been to more accurately control additives like gypsum and limestone addition, however, it is now also able to control flyash and slag or mixtures of both.
