Loesche recently received an order from the cement manufacturer Seven Circle Bangladesh Ltd. (SCBL), part of the holding company Shun Shing Group (SSGIL)/Hong Kong, for a vertical roller mill for its new grinding plant in Gazipur, near the capital Dhaka.
With four main and four support rollers, the mill will be used for grinding clinker/slag and will have a throughput capacity of 400 t/h. This makes it the largest Loesche cement mill in the emerging Bangladeshi market.
A mill of the same type has already been successfully installed at DG Khan Cement in Pakistan and with a grinding table diameter of 7.2 m, it is one of the world’s largest cement mills. This mill has now been successfully put into operation and in the first 30 operating hours had already ground an average of 400 t/h of Ordinary Portland Cement at a fineness of 3950 Blaine.
The cement mill for SCBL is equipped with the compact COPE drive (Compact Planetary Electric Drive) and has a drive power of 9.2 MW. The COPE drive concept was specially developed by Loesche together with Renk for powerful vertical roller mills with drive power of above approx. 8.0 MW. Up to eight drive units drive the mill’s grinding table via a planetary stage. The drive units can each be engaged or disengaged.
At the same time as the order for the new grinding plant in Gazipur, Loesche also received an order for a further mill for end customer Shun Shing Cement Mills Ltd. (SSCML), also part of the Shun Shing Group. An LM 53.3+3 CS will be used, with three main and three support rollers and a drive power of 4650 kW. The mill will grind clinker and slag at a capacity of 180 t/h in a newly-built grinding plant belonging to SSCML in Shikalbaha near Chittagong.
The scope of delivery for both mills includes the complete mill as well as the static mill components. Both mills will continue to be equipped with Pronamic wear parts, developed by Loesche, for the main rollers, support rollers and the grinding table.
It is anticipated that commissioning of both grinding plants will take place in autumn 2019.
