Abstract：To further achieve energy conservation and consumption reduction,multiple optimization measures were implemented for the single-drive double-circle flow cement grinding system in cement production.These included replacing overlay welded roller sleeve of the roller press with studded roller sleeves,adopting lightweight liners and"Z"-type high-efficiency activation rings in the ball mill,adjusting the grinding media gradation,upgrading to high-efficiency energy-saving fans,improving material distribution uniformity,enhancing production conditions in the grinding workshop,and optimizing system process parameters.Post-optimization,the system demonstrated stable operation and consistent product quality.When producing P·O42.5 ordinary cement,the system output increased to 260t/h,and the power consumption of the cement grinding process decreased to 24.8kW·h/t,meeting China's national first-level energy consumption limit standard.The significant energy-saving effects provide valuable reference for energy efficiency improvements in cement industry grinding systems.
