GrindingTaking the vertical roller mill as the core, a short flow primary powder collection process is adopted, which is combined with the feeding system, dust collection system and drying system. It can grind all kinds of medium and low hardness materials (coal, limestone, lime, slag, manganese ore, bentonite, etc.) from millimeter level to micron level. -

Active limeCompared with ordinary lime, the advantages of active lime are: Less volume density (1.5～1.7g/cm3) Larger specific surface area (1.2～2m2/g) Higher porosity (up to 50%） Mineral crystal of calcium oxide is finer (1-3μm) Higher chemical purity (CaO＞92%，SiO2+Fe2O3+Al2O3＜3%，S＜0.02～0.05%) Lower content of residual CO2 (LOI≤2～5%） Higher activity (up to 380ml) Most of premium active lime are being produced with rotary kiln technology in USA, -
