Gypsum powder production process can be divided into direct and indirect calcining calcination two, direct firing of flue gas is about fluidized bed for media on the heating furnace and desulfurization gypsum plaster powder of the dust in the flue gas to the quality have certain effect, but investment, low production cost less; Indirect calcining is using the hot air as medium of heating furnace and desulfurization gypsum calcination process quality of gypsum intermediary epicuticular negative impact, but greater investment, production cost is higher; This process is the main advanced technology, using heat source, can provide about fluidized bed to minimize the coal consumption, and make full use of hot, daily output 100 ~ 1000 tons, is currently in the process of industrial gesso firing the ideal equipment. Total power: 120 KW. If you want to seek advice or need the equipment can phone or email to contact
