Longshan Cement Plant belongs to Changxing Mining Group and has no affiliation with Conch. Yingde Longshan Cement Plant has three production lines with an annual output of 6 million tons, which basically runs on the same plot as the four production lines of Yingde Conch. Changxing's management comes from the former management of Conch, and has been authorized by Conch to sign the trademark, and also sells products under the brand trademark of Conch. Therefore, the scale of the seven production lines of Yingde Longshan and Conch is already the largest cement plant in Asia. They are partners, mutual benefit and win-win situation. Yingde is now the largest cement production base in Guangdong, and it is also because of the scale operation of Conch and Changxing Mining.
