Rotary Kiln,Cement Rotary Kiln,Clinker Rotary Kiln

The kiln used in wet type production, which produces slurry with water content of 32%-40% from raw materials, is called the Wet Type Rotary Kiln. Due to the liquidity of the slurry, the raw materials are sufficiently mixed, making clinker of high quality, which is the main advantage of wet production.

Oxyfuel combustion in rotary kiln lime production

Oxyfuel combustion in rotary kiln lime production. Oxyfuel combustion aims to concentrate carbon dioxide in the flue gases enough for utilization or storage. Replacing air (79% nitrogen and 21% oxygen) with pure oxygen can decrease the volume of flue gases from the process.
