Annular shaft kiln
The art of modern lime calcining
This kiln technology produces lump lime and dolime of high to medium reactivity. Based on the original technology of Beckenbach Wärmestelle, the thyssenkrupp kiln combines tradition with modern design features to present an annular shaft kiln that is easier to handle and much more reliable ever.
Unlike other shaft kilns even problematic limestone is usable in applying gentle burning. The almost stoichiometric combustion conditions produce an off-gas owning the highest contents in Carbon dioxide, ready for PCC production and the soda industry.
