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.
