Pulverised Fuel Mills – Power Stations of the UK

A pulveriser or pulverised fuel mill grinds coal into a fine powder. They contain a number of steel balls inside a rotating drum, causing the balls to tumble. The coal is then in, where it is crushed between the balls. Air is blown through the drum to carry the pulverised fuel to the boilers.
