Description

Technical Field

[0001] The utility model relates to the technical field of air ducts, in particular to an air duct with good sealing performance for a fan used in clinker production. Background Art

[0002] Cement clinker is a semi-finished product obtained by mixing limestone, clay and iron raw materials in appropriate proportions, burning them until they are partially or completely melted, and cooling them. In the cement industry, the most commonly used silicate cement clinker has the main chemical components of calcium oxide, silicon dioxide and a small amount of aluminum oxide and iron oxide. The main mineral components are tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium aluminoferrite. After silicate cement clinker is ground with an appropriate amount of gypsum, it becomes silicate cement. In English, cement is sometimes written as cement.
