Coal Mine Guide Bnsf

Lignite is available from BNSF-served surface mines in North Dakota. This lignite field is part of the Great Plains coal area. Heat values of the deposits in this area range from 6,500 to 7,000 BTU/lb. The lignite is primarily burned by local power plants, but can be used by any properly designed stokers, coal-fired units and cyclone furnaces.

process grinds the powder materials by impact/collision attrition. Milling can be dry milling or wet milling. In dry milling, about 25 vol% of powder is added along with about 1 wt% of a lubricant such as stearic or oleic acid. For wet milling, 30-40 vol% of powder with 1 wt% of dispersing agent such as water, alcohol or hexane is employed.
