Latest Patents

Siwei Li holds a patent for a method titled "Method for preparing cementing material by sintering activation of coal gangue." This method involves several steps: first, crushing coarse-grained coal gangue to a predetermined particle size. Next, the crushed coal gangue is mixed with a composite additive and water, followed by granulation. The granulated pellets are then ignited and exhausted in a sintering machine to produce decarburized coal gangue sinter. After cooling, the sinter is crushed and finely ground to create a coal gangue active mixture. Finally, this mixture is combined with fly ash, quicklime, and gypsum for injection molding, mold removal, and curing to yield a coal gangue-based cementitious material. Siwei Li has 1 patent to his name.
