Limestone mill for desulfurization

2021-9-1 · Power plants choose limestone as the desulfurization curing agent based on the fact that limestone has a wide range of sources, low price, and high desulfurization efficiency. Limestone powder for desulfurization requires a particle size of 250 mesh or 325 mesh (45 μm), of which 325 mesh limestone powder has a better desulfurization effect.
