Abstract:
The invention relates to a process for processing brown coal for combustion and/or gasification for the purpose of power generation, wherein the brown coal moist from the pit is firstly subjected to preliminary crushing and is subsequently comminuted. The milled coal is then fed to drying in a fluidized-bed dryer. The process is characterized in that the milling apparatus is followed by a control sieving facility, with the sieve opening being selected so that essentially 100% of the brown coal passes the sieve.
