Coal, coke and fly ash all have one thing in common – they need to be milled before use. Milling these materials to a finer particle size facilitates the removal of contaminants. Union Process designs and manufactures several dry grinding Attritors that are well suited for this application, including the SD Series and HSA Series.

The grinding process is controlled to obtain a powder with a broad particle size range, in which typically 15% by mass consists of particles below 5 μm diameter, and 5% of particles above 45 μm. The measure of fineness usually used is the ' specific surface area ', which is the total particle surface area of a unit mass of cement.
