Small plants should preferably use production lines with preheater kilns. 2 Restrict the construction of backward production processes, and prohibit the construction and expansion of production processes with high energy consumption such as wet-process rotary kilns, Lipol kilns and dry-process hollow kilns. 3 Prohibit the construction and expansion of various vertical kiln production lines and the expansion and transformation of vertical kilns with a diameter of 2.2m or less. Eliminate earth (egg) kilns, ordinary vertical kilns, mechanical vertical kilns with a diameter of 2.2m or less, and dry-process hollow kilns and wet-process kiln production lines with a diameter of 2.5m or less (except for those that have produced special cement before the end of 1997).
4 The determination of process equipment and automation control level should be based on national conditions and comprehensive benefits, and combined with the international level of technological development, while ensuring the realization of various technical and economic indicators.
5 Equipment, components and instruments that need to be purchased from abroad should be determined after technical and economic demonstration.
