A Study on the Continuous Manufacturing Technique of A-Gypsum

Abstract:

Article Preview

The traditional manufacturing technique of “liquid phase method” used in a-gypsum producing is with a lot of defects as follows: low quality product caused by the long-time drying, high expense on the drying device and waste of energy in pulverization modification. Our research is aimed at using a continuous manufacturing method to try to fix all the defects that come along with the traditional manufacturing technique. First we heat the gypsum serofluid, causing it to flow, while the dehydration of crystallization water and the formation of hemihydrate gypsum crystal will take place at the same time. Then an instant decompression will make the serofluid blow into a drying tower, causing a vapour explosion, and finishing the two processes of drying and modification at the same time. [1]
