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.
The particle size of limestone powder for desulfurization is 250 mesh or 325 mesh (45 μ m), and the desulfurization effect of 325 mesh limestone powder is better. To prepare such fine limestone powder, the mill mainly adopts Raymond mill, pendulum mill, ball mill or European mill. In the past, Raymond mills and ball mills were used more.
