coal has been reduced to the desired fine powder. Some power stations crush coal into fine dust in pulverising mills. These mills work by repeatedly dropping massive steel balls on to. the coal until it is crushed into fine coal dust. The steel balls used. at Drax, for example, are hollow, about 73 cm in diameter, and weigh.

Particle sizes were varied by changing the milling time, keeping mill power, batch volume, and recirculation rate constant. As expected, mean particle size decreased with longer milling. A lignite coalbased carbon had the smallest mean particle diameter at 169 nm, while the woodbased carbon had the largest at 440 nm.
Coal dust often and interchangeably known as anthracite is a material produced by the fine milling of anthracite coal. Anthracite is regarded as the superior form of coal. Coal dust also proves its mettle as a binder in other scenarios.. As binders are added prior to compaction and are responsible for particle agglomeration, it is critical that several factors are considered and .
The powdered coal was sieved and sent off to the iron foundries. The mill was equipped with a Diesel engine before the Second World War as an auxiliary motor to keep the mill going. The mill's working parts at that time consisted of two pairs of horizontal millstones and five pairs of edge runner stones.
of hot air blasts this powdered coal from the mills through coal burners to the boiler furnace where it burns like a gas. The hot air not only transports the coal from the mills to the boiler furnace, it also dries out the coal. In a boiler, heat released by the burning coal is absorbed by many kilometres of tubing which form the boiler walls ...
