The types of mills are distinguished by their working principles: by pressure, impact, hammer, or shear. Mills could be equipped with a screen for grain size control and separation. The FAM product range includes impact mills, roller mills, hammer mills, ball mills and rod mills.
For a lime FGD system, a lime slaker processing pebble lime is required in place of the limestone wet ball mill. To facilitate the disposal of the solid waste, or to produce a saleable product in the form of high quality gypsum, a forced oxidation system may be utilized to oxidize the main reaction product, calcium sulfite, to gypsum.
A ball mill consists of a rotating drum loaded with steel balls that crush the,limestone by the action of the tumbling balls as the cylindrical chamber rotates. Ball mills used in FGD systems fall'into two categories.
