As an important basic industry of the national economy, the green development of cement industry is of great significance to realize the goal of “dual carbon”. This report systematically reviews the technological development history of China's cement industry, and focuses on analyzing Sinoma's current innovative achievements and application practices of advanced pyro, grinding and environmental protection technologies and equipment. Research and practice show that through low resistance and high efficiency preheater, gradient combustion self-denitrification precalciner, new heat insulation materials and other pyro technologies, the heat consumption of the pyro system can be significantly reduced; the application of grinding technologies such as roller press finished grinding and vertical mill significantly reduces the system's power consumption; the vertical mill technology has been widely used in metallurgy and sand making industry by virtue of its characteristics of low energy consumption and high stability; the environmental protection technologies such as dust removal, SCR denitrification and wet desulfurization have realized ultra-low emission of dust, NOX and SO2 in cement factories; low energy consumption suspension calcination activation technology developed based on precalciner technology has been widely used in water purification agent, clay calcination and gangue calcination. In the future, Sinoma will continue to push forward technological innovation and green intelligent equipment upgrading to promote the green development of cement industry.
