China: Loesche GmbH has completed work on the largest slag mill in the world for Shanxi Taigang Stainless Steel Co (TISCO) in Taiyuan, China achieving a new record product rate of producing 255t/hr blast-furnace slag meal. The Loesche type LM 63.3+3 vertical mill for grinding granulated blastfurnace slag was originally ordered by the Taigang Group International Trade Co in September 2011. It started operation in March 2014.

At the TISCO steelworks the LM 63.3+3 has now been used for the pure grinding of granulated blast-furnace slag for the first time. The mill is driven by a motor with an output of 7400kW, the most powerful motor to have been installed so far by Loesche in a mill. The projected guarantee values of 255t/ hr granulated blast-furnace slag at a fineness of 4400 Blaine are reliably attained here. This is also ensured by the newly developed Loesche LDC classifier, used in the grinding plant and ideally customised to the Loesche mills.

The first Loesche LM 63.3+3 mill started production at Nallalingayapalli, India in 2009. It attains a peak value of 367t/hr ordinary portland cement at 3000 Blaine or 371t/hr portland pozzolana cement at 3400 Blaine.
