混合晶种配料节能效果明显何诗新中国建材研究院发明的“添加晶种水泥立窑煅烧技术”经山东博兴水泥厂、广西灵山水泥厂等四家水泥企业的生产实践证明，经济效益十分明显。但是实施该项新技术需要挑选优质熟料按３～３．５％的比例返回生料配料，这样熟料重复返回，花工多... The energy saving effect of the mixed crystal seeding ingredients is obvious. The production technology of the “adding seed cement shaft kiln” invented by He Shixin China Building Materials Research Institute has proved that the economic benefits are obvious through the production practices of four cement companies including Shandong Boxing Cement Factory and Guangxi Lingshan Cement Factory. However, the implementation of the new technology requires the selection of high-quality clinker to return raw meal ingredients at a ratio of 3 to 3.5%, so that the clinker is returned repeatedly.
