Description

Technical Field

[0001] The utility model relates to the technical field of cement clinker dust reduction, in particular to a dust reduction mechanism for a cement clinker crusher. Background Art

[0002] Cement clinker is a product made of limestone, clay, iron and other main raw materials in appropriate proportions, which is partially or completely melted, fired, and cooled to a semi-finished product. In the cement manufacturing industry, silicate cement clinker is the most commonly used, and its main chemical components are calcium oxide, silicon dioxide, and a small amount of aluminum oxide and iron oxide. In the production process of silicate cement clinker, crusher is an indispensable equipment. However, when using crushers to crush clinker, there is often a lack of corresponding dust collection devices, resulting in a large amount of dust generated during the crushing process, which is not conducive to environmental protection and also has a certain impact on human health.

[0003] The existing publication number is CN217940430U, which is a low-emission dust collecting device for cement clinker production. Its dust collection hood is composed of a square hood and a conical hood.
