Technical Field

[0001] The utility model belongs to the technical field of gypsum processing, in particular to a pulsator structure for homogenizing and stirring. Background Art

[0002] Gypsum is a monoclinic mineral and a hydrate whose main chemical component is calcium sulfate. Gypsum is a widely used industrial material and building material. It can be used as a cement retarder, gypsum building products, model making, medical food additive, sulfuric acid production, paper filler, paint filler, etc. In the gypsum production process, auxiliary materials need to be added to the gypsum according to the type of gypsum produced.
