Annular Shaft Kiln
The Annular Shaft Kiln is characterised by its annular shaped shaft cross section located between an outer and inner refractory lined cylindrical steel shell.
One of the main features of this kiln type is the continuous stream of exhaust gases with a high CO2-content, ranging between 26 and 32 %, depending on the type of fuel used. Furthermore the kiln allows adjusting the reactivity of the quicklime produced from soft burnt to medium burnt. These characteristics make the Annular Shaft Kiln especially suitable for producing burnt lime for the PCC and soda industries.
The Annular Shaft Kiln can be fired with a wide range of fuels. The daily output of burnt product ranges between 200 and 600 tpd.
