 Fluidized bed calcining process:
As the gypsum industry developes, the gypsum powder demand becomes larger and larger in many fields.Meanwhile the requirement for gypsum powder quality becomes more strict. Therefore the gypsum power process improves grandualy. Drying and dehydrating the raw gypsum powder is a critical process and the most difficult to control. After many years of research and experiment we have successfully developed the advanced calcining device-fluidized bed calciner, suitable for all kinds of gypsum powder prodution.
The Function principle
The fluidized bed calciner mainly is composed of dense small diamter piping coils which radiates heat of enclosed thermal oil through heat exchanger. At the bottom of the calciner a Roots blower is installed.
The blower suckes cold air into the calciner through the grid plate.The blown raw powder inside the calciner becomes boiling. At certain temperature the dried and dehydrated gypsum powder turns lighter and overflows out. The finish powder has a stable quality,and its cristal water content and final setting time are easy to control. The calciner is equipped with high efficienct (more than 95%) dry electrostatic precipitator to control air pollution.
