FGD: KREBS hydrocyclones are used to classify limestone ball mill discharge in the reagent preparation area of wet flue gas desulfurization (WFGD) scrubbers in coal fired power plants. In the forced oxidation process,the limestone reagent reacts with absorbed SO2 from the boiler exhaust, forming gypsum as a byproduct.

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.

Furthermore, Wang et al. (2005) highlighted the systems commonly adopted for the grinding of limestone such as long drum or tube mill and the Hardings ball mill. Generally, these ball mills consist of a rotating drum loaded with steel balls that crush the limestone by the action of the tumbling balls as the cylindrical chamber rotates, until ...
