Gypsum plaster making machine  Introduction
  With the development of gypsum industry, there is a large demand for quantity  and high quality of gypsum powder. Therefore, the high level of gypsum powder production technology is required. In the process of gypsum powder production, drying and dewatering is the key link, which is also the most difficult one to control. In order to solve this problem, we develop a new type of drying and dewatering equipment---ebullience calciner, which is produced based on the exploring of the gypsum production filed. Following is the brief introduction of the gypsum production technology and ebullience calciner working principle.

The working principle of ebullience calciner
The main working principle of the ebullience calciner drying system: the main part of the ebullience calciner is formed by the small-diameter cooling coil pipes. The heat transfer oil is piped into coil pipe and releases heat into the internal of furnace after exchanging heat. Roots blower which can blow the cold wind into the furnace by air distribution plate is equipped at the bottom part of the ebullience calciner, by blowing let the powder in  furnace boiling. And under certain temperature, the powder which has been dried and without crystallization water becomes light, so it can flow to the outlet automatically. The quality of the gypsum powder produced in this way is stable and the content of crystallization water is large, so it is easy to control the time of solidification. In addition, the dry electrostatic precipitator was equipped to this machine, the efficiency of dust removal can reach more than 95% after the dust removal, eliminating the dust pollution.
