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

Collieries and Coal Breakers Up the Woods
Once the coal was cleaned and sized as best as possible, the remaining dirt, slate and other impurities were dumped outside the breaker in a large refuse pile known as the culm bank. Often these culm banks in time grew in size to dwarf the adjacent coal breaker. The breaker process was far from perfect with much coal crushed beyond practical use.
Coal National Geographic Society
However, coal releases impurities such as sulfur when it is heated, which can make the resulting metal weak. As early as the 9th century, chemists and engineers discovered a way to remove these impurities from coal before it was burned. Coal is baked in an oven for about 1236 hours at about 1,0001,100 °C (1,8002,000 °F).
