Lignite contains 25%–35% carbon and has the lowest energy content of all coal ranks. Lignite coal deposits tend to be relatively young and were not subjected to extreme heat or pressure. Lignite is crumbly and has high moisture content, which contributes to its low heating value. Lignite accounted for 9% of total U.S. coal production in 2020.

High speed impact mills are mainly used in pulverizing lignite. Today all boiler designers opt to use ball or vertical spindle mill for coal other than lignite. While selecting the type of mill boiler designers must clearly understand the coal characteristics, the overall system being used, and the maintenance requirement.

Also, the high ash/moisture content of lignite makes its long distance transport very costly and increases overall environmental impacts. Consequently, the use of lignite has been, in the past, limited to power generation at, or close, to the mining site. Another important issue regarding the use of lignite is its environmental impact.

High speed impact mills are mainly used in pulverizing lignite. Today all boiler designers opt to use ball or vertical spindle mill for coal other than lignite. While selecting the type of mill boiler designers must clearly understand the coal characteristics, the overall system being used, and the maintenance requirement.

The Stora Enso Sunila mill is designed to produce 50,000 metric tonnes of lignin per year, or 22 percent of the lignin. Lignin lean black liquor and wash water can be evaporated like a normal black liquor, and if the production of pulp is increased and the mill's energy consumption is reduced, up to 70 percent of the lignin can be removed .
