General comment The new dry process method holds a market share of 61.82%, and the scale of the clinker production over 4000 tons per day accounts for 29.32%. In order to reflect the present environmental impact of China's cement industry, taking into account the adjustment of the industry structure and development status in recent years, and considering the differences in cement production technology and the size of different enterprises, China's cement industry is classified into four categories: large new dry process (>4000 tons of clinker per day), medium new dry process (2000~4000 tons of clinker per day), small new dry process (<2000 tons of clinker per day), and shaft kiln (<2000 tons of clinker per day). |
