Description

Screening plant for cement

Technical Field

The utility model relates to the technical field of cement production equipment, in particular to a screening device for cement.

Background

The cement is a powdery hydraulic inorganic cementing material, is added with water and stirred to form slurry, can be hardened in air or water, and can firmly bond materials such as sand, stone and the like together.

Finished cement of a cement manufacturing enterprise generally needs to be stored in a cement warehouse for several days before leaving the factory, so that the stability of the cement is ensured, and the temperature of the cement is further reduced. However, in some areas, due to the long-term humid climate and the characteristics of cement, micro water molecules in the cement can automatically adsorb a large amount of moisture in the air to form particles and even agglomerate, and if the water molecules are directly screened and discarded, the water molecules are inevitably wasted, and if the water molecules are directly used, the quality of the cement is affected, so that the screening device for the cement needs to be provided.
