A process for preparing a briquette is disclosed. The process comprises a coal with a caking substance having a softening point of 20 DEG -40 DEG C. or with a caking substance having a softening point of above 40 DEG C. and a solvent which has fluidity at normal temperature and is compatible with the caking substance to a coal for making briquettes, powerfully mixing at a temperature of above 10 DEG C., preferably of 20 DEG -50 DEG C., for 1-10 minutes, by using a mixer provided with a mixing tool which is rotated at a speed of more than 5m/sec. peripheral velocity and/or a mixer provided with a mixing tool which applies a pressure of more than 45kg/cm2; and briquetting by using a roll press, whereby a briquette is obtained having a shutter strength of more than 80 and a trommel strength of more than 90. |
