Located in Tongling, Anhui province, these two lines were invested by Conch Group which is China’s biggest cement producer. The first line of the two was ignited on May 26th and load tested on June 5th 2004. Ignition, trial operation, load test and design production output were realized nearly at the same time. Commencement to production merely took 18 months, 1 year shorter compared with the completion time for foreign projects at the same scale. This is an unprecedented success.
