Abstract:
    The invention relates to a process for crushing raw lignite. The raw lignite is dried with an exit temperature after drying of approximately 70 DEG to 85 DEG C. The dried raw lignite is then crushed. This crushing of the dried raw lignite is performed in an air-swept roller mill, in which the crushing and cooling of the lignite particles is brought about by the inflowing cold and/or ambient air to a temperature range of below 60 DEG C.
Time: 10
