煤矸石制砖余热发电研究
煤矸石是煤炭开采及加工过程中排出的主要固体废弃物,其组成为多种岩石的混合物。煤矸石的生产与煤炭产量分布具有密切联系,中国的煤矸石产生量相当于煤炭产量的10%～15%,2007年中国共生产原煤25.2亿吨,同期煤矸石产量约为3亿吨,

高含量蒙脱石煤矸石制砖工艺的研究及实施
The montmorillonite content was as high as 42% for the coal gangue in Inner Mongolia Dayan Coal Co., so it was difficult to manufacture brick with this coal gangue. The production technology was reconstructed in order to resolve these difficulties. The reconstruction included materials mixing, improving raw materials fineness, extending ageing period, reducing forming resistance,increasing extrusion stress, low temperature drying and long period firing, etc. After the reconstruction, the production ability and qualified products were also improved.
