The lignite is recovered by surface mining using a giant electrically-powered dragline constructed at the mine site to remove 20 to 140 feet of dirt and expose the lignite below. The dragline is as tall as a 20-story building, weighs 8 million pounds, and has a 77 cubic yard bucket. The bucket holds enough dirt to fill a one car garage.

Bituminous: Even greater pressure results in the creation of bituminous, or "soft" coal. This is the type most commonly used for electric power generation in the U.S. It has a higher heating value than either lignite or subbituminous, but less than that of anthracite. Bituminous coal is mined chiefly in Appalachia and the Midwest.

2) Inner automatic Thin-Oil lubricating system: the traditional mill adopts grease lubrication, so the lubricating resistance is stronger, the temperature will be higher soon, the bearing life is shorter. MTW series mill adopts inner L.O. pumps, so the main shaft bearing and bevel gear can be lubricated without an additional lubrication system.

Lignite coal is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It is considered to be the lowest rank of coal due to its relatively low heat content. It has lowest carbon (C) content amongst all types of coals. It is mined all around the world and is mainly used as a fuel for steam and electric power generation.

The Bureau of Mines studied lignite pulverization in a laboratory ring-roller mill. Both moisture content and the source of lignite were found to be important factors in pulverizer operation. Reduction of moisture content increased capacity and reduced power consumption, but predrying is more effective than in-the-mill drying in improving pulverizer operation.

Lignite has the lowest ranking in the coal classification system, and it is mostly used as fuel in the power sector. Lignite's colour ranges from brown to black (see Figure 2.7) and its heating value is less than 19.306 KJ/Kg. Due to the fact that lignite deposits are geologically young they may contain plant debris.
