Hot fine coal briquetting with using double roll press in diameter 400 mm in several briquetting conditions were tested in order to research fundamental phenomena in SCOPE process. Effects of hot briquetting conditions and coal qualities to briquetting yields and briquette strengths were researched. The followings were found that : (1) Briquetting yields and briquette strengths were increased with the increase of briquetting temperature, and with the decrease of cup volume. (2) Briquetting yields and briquette strengths were increased with the increase of the number of rotation of screw feeder, which was used to supply compulsorily coal. (3) Briquetting yields and briquette strengths were decreased with the increase of the number of rotation of rolls. But increasing the number of rotation of screw feeder was recovered briquetting yields and briquette strengths. (4) Briquette strengths were increased with using more fluidity coal for coking and non- or slightly coking coals. (5) Briquetting yields and briquette strengths were increased little in wider coal diameter distribution.
