Hao Laiyin speaks at the Guangdong cement energy-saving and carbon-reduction meeting
On 19 November 2025, Chairman Hao Laiyin spoke at the Guangdong cement industry meeting on energy saving and carbon reduction in Longmen, Huizhou, presenting Jinxing JX special corundum composite brick and spiral masonry for cement rotary kilns.
Hao Laiyin, chairman of Zhengzhou Jinxing Refractory Co., Ltd., focused on the technical requirements of energy saving and carbon reduction for cement rotary kilns, analysed problems still to be resolved in current kiln operation, and introduced the development and characteristics of Jinxing JX special corundum composite brick and the engineering application of spiral masonry of refractories in cement rotary kilns. Through specific application cases, he showed the notable results of this technology in improving heat exchange of kiln materials, lowering smoke-chamber temperature and reducing thick coating, offering plants a new approach to production management.
On 19 November 2025, the Guangdong Cement Industry Association held the provincial cement industry meeting on energy saving and carbon reduction in Longmen County, Huizhou. More than 80 people took part, including principal leaders of cement producers across the province, officers in charge of energy saving, safety and environmental protection and occupational health, technical staff and experts. The meeting followed its agenda closely, with in-depth discussion on policy interpretation, technical innovation and practical experience, to chart a greener and lower-carbon path for the industry.
The meeting was chaired by Xiao Huiyu, deputy secretary-general of the Guangdong Cement Industry Association. Wu Jikun, an engineer at the Guangdong Provincial Academy of Environmental Science, focused on key points of assessment and monitoring policy for ultra-low-emission upgrading in the cement industry, gave a detailed reading of the Opinions on Promoting the Implementation of Ultra-Low Emissions in the Cement Industry, and set out requirements and a roadmap, to help enterprises advance assessment, monitoring and public disclosure of ultra-low-emission upgrades.
Zhang Weijie, an engineer at the Guangdong Provincial Academy of Environmental Science, explained environmental-management requirements for cement-industry capacity-replacement projects. He gave a careful account of the main points of environmental management for capacity replacement, key areas of environmental supervision in the cement industry, post-permit management of pollutant discharge licences, and requirements for pollution prevention and control.
Li Jinbiao, chief engineer of Guangdong Tapai Group Co., Ltd., drew on plant practice to present engineering cases of spiral masonry of refractories in cement rotary kilns. After one year of using spiral-masonry refractory bricks, Huizhou Tapai effectively curbed the formation of a long secondary coating at the kiln inlet, removed a long-standing safety risk in the system, and kept calcination on a normal footing. The practical case offers a useful reference for other enterprises and for technical upgrading in the cement industry.
Xu Richang, vice president and secretary-general of the Guangdong Cement Industry Association, delivered the 2025 Report on Energy Saving and Carbon Reduction in Guangdong’s Cement Industry. The report reviewed the current work, results and remaining problems, and set out the 2026 plan, giving the industry clear goals and direction.
Li Li, executive vice president of the association, announced the results of the 2024 energy-efficiency benchmark selection for the Guangdong cement industry. After a comprehensive evaluation of participating enterprises, 24 clinker lines at 13 enterprises, including Yingde Conch Cement Co., Ltd., were selected as 2024 Guangdong cement industry energy-efficiency benchmark lines; 10 enterprises, including China Resources Cement (Zhanjiang) Co., Ltd., were named 2024 advanced enterprises for power consumption in the cement grinding section; and Guangzhou Zhujiang Cement Co., Ltd. was named the 2024 energy-saving progress enterprise. Plaques were presented at the meeting.
In the afternoon, participants visited Huizhou Tapai Cement Co., Ltd. to exchange views and study its energy-saving and emission-reduction upgrades and management practice.
The meeting further clarified the roadmap and timetable for energy saving and carbon reduction in Guangdong’s cement industry. Participating enterprises said they would take it as an opportunity to speed up policy implementation and technical upgrading. As policy support continues and technical innovation advances, the industry is expected to move toward a virtuous cycle of better capacity, higher energy efficiency and lower emissions, supporting the province’s 14th Five-Year Plan energy-saving and carbon-reduction goals.
