Background

The wet calcium carbonate production is that the low-mesh calcium carbonate (generally 325-400 meshes) prepared by dry grinding and water are prepared into slurry with certain solid content, and then the wet grinding and drying are carried out to prepare the superfine calcium carbonate. The wet-process calcium carbonate is widely applied to industries such as films, cables, plastic pipelines and the like due to the advantages of fine fineness and large specific surface area.

The process of preparing the slurry by the wet method of the calcium carbonate is to stir and mix calcium carbonate powder, tap water and the pretreated dispersing auxiliary agent in a stirring barrel for a certain time according to a certain proportion.
