Shaft kiln bauxite, the bauxite calcined by shaft kiln. The raw material – bauxite ore is loaded from the top of kiln together with coal powder and combustion improver, the fire of calcination comes from kiln bottom, about 1300-1400 degree. After the complete calcination, the bauxite is carried out from the bottom.
Shaft Kiln Bauxite:0.5-1mm,1-3mm,3-5mm,5-10mm,10-15mm and other customers size
