Lignite, or brown coal, is the lowest rank of coal. Because of its low energy density, lignite coal is inefficient to transport and is not traded extensively on the world market compared with higher coal grades. About 79 percent of lignite coal is used to generate electricity, 13.5 percent is used to generate synthetic natural gas, and 7.5 percent is used to produce fertilizer products (anhydrous ammonia & ammonium sulfate). A very small percentage is used as home heating fuel, for use as fertilizer and for use as oil well drilling mud.
You can use jaw crusher for the primary lignite crushing. The final size can be adjusted according to your requirement. For higher capacity, just choose higher model of jaw crusher. Lignite coal mills vary from traditional ball mill to the modern series vertical mill. Especially in the lignite coal grinding process, we have made special treatment to improve the coal quarry quality considering the environment protection.
