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.
