The briquetting process includes pulverizing raw coal to produce a feed, feeding the feed into a feed bin for degassing, adjusting the temperature and the water content of the feed in the feed bin, and feeding the feed in the feed bin into a briquetting apparatus for briquetting to form coal briquettes. The raw coal briquetting process of the preparation method is suited to a wide variety of coal, including non-caking coal.
