the inner edges of the impact plates. At the same time, the pulverised lignite is mixed thoroughly with flue gas, resulting in a high drying efficiency due to the abrupt increase in the surface of the lignite particles. Model of beater wheel mill N 200.45 built by Alstom Power Stuttgart Rolling Bearings in ALSTOM Beater Wheel Mills
This mill uses central horizontal shaft which has a number of arms, and a beater of different design is attached to these arms to beat the coal to be pulverized. 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.
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.
Tests on the boiler were performed during low load operation and the lignite share reached over to 36% by mass. The predried lignite, kept in dedicated separate bunkers, was mixed with bituminous coal just before the coal mills. Computational fluid dynamic (CFD) simulation of a cofiring scenario of lignite with hard coal was also performed.

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.
Turbo Mill REF Turbo Mills, type REF are impact mills for medium fine to finest grinding and fine fiberizing of soft to medium hard materials (about 4 according to Mohs) to a particle size up to 5 micron: Typical materials to be processed are: Medium hard Minerals Raw gypsum, anhydrite, bentonite, dry and wet clay, talc, medium-hard ores, graphite, micra, diatomaceous earth, fluorspar, chalk ...
These mills are produced with capacities up to 100 t h − 1 and wheels with a diameter of 4 m. They are mostly used for high-moisture coals, lignite (brown coal), limestone, and other soft materials. The authors are not aware of any case where this type of mill has successfully been used to fire neat biomass.

The high-speed mills are used mainly for lignite. Operation Of Bowl Mill Pulveriser . ... Larger pieces of coal are broken by impact and the fine grinding is done by attrition and crushing as the balls roll and slide within the charge. Hot air flow is induced through the mill in order to dry the coal and remove the fines from the pulverizing zone.
