How Gypsum is Made - AWCIcally combined in the gypsum itself. The result is stucco, a very dry powder that, when mixed with water, will quickly rehydrate and “set up,” or harden. The stucco is fed into large bins, which then feed it into the pin mixer, the first step on the “wet end” of the manufacturing process. The stucco is blended with water and other.Gypsum powder production line,Gypsum powder process line .Apr 28, 2015 .
