Calcination is an important part of gypsum processing, quality of calcination directly determines quality of the final product.
Gypsum powder enters the fluidized gypsum boiling furnace for calcination after being pre-dried.
Discharge temperature of calcination process is 150-160 °C, by adjusting boiling furnace internal temperature, etc.,
parameters of the finished building gypsum can be adjusted to meet different requirements.
Coal and gas (light oil) burns serve as heat source, hot air as heat exchange medium, thermal efficient > 85%; preheating utilization system is applied, leading exhaust gas to the outlet position, getting it mixed with the high temperature flue gas stroke, to effectively save energy.
