The processing technology of gypsum powder
The process flow of gypsum powder mainly includes four steps: crushing, grinding, grading, and powder collection. The first stage is fragmentation. The large gypsum blocks are crushed by a crusher to a feed fineness that can enter the grinding machine, usually between 15 millimeters and 50 millimeters. The second stage is grinding powder. The crushed small pieces of gypsum are se
