Calcination equipment is the key link of gypsum powder production, our company has independently developed a new generation of dewatering equipment suitable for various gypsum powder production requirements - boiling furnace. The main body of the boiler is mainly composed of thin diameter dense cooling coil, at a certain temperature, after drying to remove the powder of crystal water, the weight becomes lighter, the automatic flow to the discharge port, so that the quality of the produced gypsum powder is stable, the content of crystal water, the initial and final coagulation time is easier to control.
