中国水泥工业生产技术发展与展望

Development and Prospect of China′s Cement Production Technology

中国水泥工业经过近５０年的发展已有７０００多家水泥厂，产量占世界总产量的１／４强，达４亿多吨。技术上吸收了国外的先进技术，开发了自己的实用技术和装备。目前水泥的产量和品种已基本上能满足国内市场需求，部分技术和装备已向外出口。但在生产技术、技术经济指标、环境保护及现代化程度方面与国外先进水平比较尚有较大差距。今后将进一步吸收国外的先进技术，发展自己的工艺技术和机电装备，逐步缩小与国际先进水平的差距。

s a result of the development in recent 50 years,more than 7000 cement plants are now existing in Chinawith an annual output of over 400 million tons,which are slightly more than one fourth of the total worldprOduction.Chinese own practical technology and equipment have been developed while introducing advancedforeign technology. At present China′s cement can basically meet the demand on the domestic market while partof technology and equipment have been exported.However,there are still fairly big gaps in respects of processtechnology,technico-economicaI targets,environmental protection and modernizatiOn as compared with theadvanced world levels.China will further take in advanced foreign technology,develop its own technology andequipment so as to shorten the gap gradually.
