Coal Breaker

A coal breaker was a coal processing plant which broke coal into various useful sizes. Coal breakers also removed impurities from the coal (typically slate) and deposited them into a culm dump. The coal breaker is a forerunner of the modern coal preparation plant.

Generally speaking, a coal tipple was typically used at a bituminous coal mine, where removing impurities was important but sorting by size was only a secondary, minor concern. Coal breakers were always used (with or without a tipple) at anthracite mines. While tipples were used around the world, coal breakers were used primarily in the United States in the state of Pennsylvania (where, between 1800 and the mid-20th century, nearly all the world's known anthracite reserves were located). At least one source claims that, in 1873, coal breaking plants were found only at anthracite mines in Pennsylvania.

Famous quotes containing the word coal:

    Mr. Christian, it is about time for many people to begin to come to the White House to discuss different phases of the coal strike. When anybody comes, if his special problem concerns the state, refer him to the governor of Pennsylvania. If his problem has a national phase, refer him to the United States Coal Commission. In no event bring him to me.
    Calvin Coolidge (1872–1933)
