Lignite Grinding Machine Process2019-10-19


Coal is classified into three major types namely anthracite, bituminous, and lignite. Lignite is the youngest coal from geological perspective. It is a soft coal composed mainly of volatile matter and moisture content with low fixed carbon. Fixed carbon refers to carbon in its free state, not combined with other elements. Volatile matter refers to those combustible constituents of coal that vaporize when coal is heated.

The sizing of lignite

Proper coal sizing is one of the key measures to ensure efficient combustion. Proper coal sizing, with specific relevance to the type of firing system, helps towards even burning, reduced ash losses and better combustion efficiency.

Lignite grinding process

Big lignite materials are fed to the jaw crusher evenly and gradually by vibrating feeder through a hopper for primary crushing.

After first crushing, the lignite material will transferred to impact crusher or cone crusher by belt conveyor for secondary crush; the crushed lignite materials will then transferred to vibrating screen for separating.

After being separated, the parts that can meet standard will be taken away as final products, while the other parts will be sent to grinding mills for further grinding. Size of final lignite products can be combined and graded according to customer’s specific requirement.
