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.
