The preparation of pulverized coal refers to the process of processing raw coal into coal powder with the same particle size and moisture content as the blast furnace coal injection requirements by the coal mill. The requirements for pulverized coal in the blast furnace injection system are: 80% or more with a particle size of less than 74 μm

pulverized mineral roller mill. The mineral to be pulverized enters the grinding chamber through an automatic feeder and falls onto the mill floor whereby it is scooped up by steel ploughs into the nip space between the rollers and the bull ring where grinding takes place a constant quantity of air is circulated through the mill and system

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.

Pulverized coal injection (PCI) is a process which involves injecting large volumes of fine coal particles into the raceway of the blast furnace (BF). Pulverized coal is an important auxiliary fuel used in the BF ironmaking. PCI provides auxiliary fuel for partial coke replacement and has proven both economically and environmentally favourable.

Pulverized-coal firing is especially suitable for very large boilers and cement kilns. A wide range of coals can be burnt, but coal preparation and gas cleaning are major cost items. 70% < 75 μm is required for bituminous coals, 80% for anthracite. Coal dried with air at 250–350°C for milling in low-, medium- or high-speed mills.
