A beater wheel mill crushes, shatters, or pulverises lignite upon impact. The fineness of pulverised coal is usually assessed on the basis of the residues on the 1 mm sieve. The typical values for pulverized lignite are well below 10% (usually between 3% and 6%), depending on quality of coal, the combustion system and boiler size [33] .
