ue to that, the capacity of the mill is increased. In the two Indian grinding stations, the fly ash is fed to the machine via two air slides. However, other setups allow for at least four inlets giving more even distribution of the fly ash over the circumference of the classifier. Summary Loesche received the order for the two grinding systems in April 2 and the FOB delivery was in November 2. Erection started in December 2 and commissioning commenced in December 2 with the first feed in February 2. By April 2, 2tph of PPC had been reached and in September 2 further optimisation was done leading to stable mill operation without any water injection for grinding bed stabilisation. As result no hot gas generator was required. The specific power consumption achieved was 5kWh lower than expected. That was in part due to the easier-to-grind clinker and fly ash compared to the assumed values, both of which had an impact on the grindability of the feed mix and the related specific energy consumption. ______________________________ IOPTIMISED GRINDING JUNE 2 INTERNATIONAL CEMENT REVIEW Figure 7: Nalagarh grinding plantFigure 6: gypsum and fly ash feed system to the mill LOESCHE Mill Type LM 5.3+3, Nalagarh, India Loesche GmbH Hansaallee 2 DsseldorfTel. +4 - 2 - 5 5 - 0Fax +4 - 2 - 5 5 - 5E-Mail: loesche FLENDER GRAFFENSTADEN loesche.de FLENDER GRAFFENSTADEN loesche speed reducers OPTIMISED GRINDING OPTIMISED GRINDING To crea Te The worlds fines engineering we are prepared To Think like no one Though before Now its time for our grinding technology.
