ABSTRACT:
The present invention is directed to a method for compressing and agglomerating coal dust without the use of bonding agents in which the coal dust is passed through a conventional roll press operating at a compressive force of at least 20 kilonewtons (kN) per centimeter (cm) of roll width. The high pressure conditions make it possible to secure suitable compression and agglomeration at temperatures below 200.degree. C.
