On October 10, 2019, Shandong Zibo Bofeng Lizhong Chemical Co., Ltd. marked a significant milestone by successfully commissioning two new production lines in its hydrogen fluoride division. Each line boasts a capacity of 50,000 tons and is equipped with state-of-the-art φ2 × 18m fluorogypsum cooling machines. The cooling efficiency of these machines surpassed initial expectations, consistently achieving a discharge temperature of less than 60°C. This outstanding performance not only enhances the operational efficiency but also ensures superior product quality.
