Therefore, dust removal devices are equipped in light calcium carbonate processing workshops.

[0003] Since calcium carbonate is in powder form and floats in the air, it is easy for calcium carbonate to adhere to the filter elements in the dust removal device. Therefore, the filter elements need to be cleaned a certain number of times to maintain their filtering performance. After retrieval, prior art 1: a utility model with the application number CN202221384746.3 discloses a dust removal device for calcium carbonate powder production.
