ANDE metallurgical provides high quality crushing and pelletizing equipment and system solutions for global customers
-
Pulverized coal injection (PCI) for furnace & kilnANDE has about 150 employees, total of them about 40 with middle and senior professional titles, majored in metallurgy, mining, mechanical engineering design, mechanical process, welding, electrical, instrumentation, automation control and etc. It has strong research and design ability in metallurgy & mining equipment and system.
-
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,
