Gypsum Powder Equipment Production Craft Introduction 1. Crushed process flow introduction Crusher breaks up large sized gypsum ore to small granule less *5mm. And then, separator mill the granule to powder with required fitness and deliver to boiling furnace to calcine. The calcined gypsum powder is delivered to grog bin for saving or to production workshop for producing. 2. Boiling furnace process flow introduction 1) Principle of work The main part of boiling furnace is composed of thin and dense radiator pipes, which is filled with conduction oil to release the heat to the inside of the furnace. Equipped at the bottom of the furnace, the Roots blower makes the powder inside the furnace into the boiled state. The powder material, baked and dehydrated with crystallization water at certain temperature, flows out through the outlet automatically. The gypsum powder produced by this procedure has stable quality and well controlled crystallization water rate, initial and final set time. Further more, by using dry electrostatic cleaner, the equipment has over *5% dust collection efficiency and eliminate the dust pollution. 2ï&frac*4;‰Simple and sustainable structure Owing to the fluidization of material, furnace doesn’t have rotatable component so that it‘s easy to be built and almost free of maintenance. Thanks to the low temperature heat source, the furnace won’t be damaged by over heating and has longer operating life. 3) Compact design and less space requirement With vertical arrangement, the dust catcher on the top of the furnace body is integrated with the boiling furnace compactly. The system occupies less space and avoids condensation of the dust catcher. 4) Low energy consumption: The heat energy, passed from the heat source to the material, is almost all used for material’s dehydration, except a small part is used to heat the cold air blew from the bottom of the heating furnace and radiates from the furnace body. Since the boiling furnace uses twice heat s
