limestone powdering machine in South Africa. By Brad Buecker, Contributing Editor. Stricter environmental regulations are forcing many utilities to install flue gas desulfurization (FGD) systems to control sulfur dioxide (SO 2) emissions below levels that can be attained by burning Powder River Basin (PRB) coal choice for many appliions is wetlimestone scrubbing, a proven technology.
The desulphurization limestone powder furnace burns fully and generally uses tail flue gas desulfurization directly. 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.
