In a trial, brown coal was pre-crushed and ground before elemental analysis to demonstrate the influence of sample preparation on the analytical results. 4 kg of brown coal (pieces of approximately 130 mm) were pre-crushed with the BB 300. Crushing obtained particle sizes of <8 mm, which were suitable for elemental analysis using for …Web
