gypsum powder plant/plaster powder machinery
1. Crushed process flow introduction
Crusher breaks up large sized gypsum ore to small granule less 25mm. and then, separator mil 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 production workshop for producing.
2.Boiling furnace process flow introduction
(1) Working theory
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.
(2) Simple and sustainable structure
Because of the fluidization material, funace doesn't need rotatable component so that it easy to 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 not only less space but also avoids condensation of the dust catcher.
(4) Low energy consumption
The heat energy, passed form 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 form the bottom of the heating furnace radiated form the furnace body. Since the boiling furnace uses twice heat source, the final heat efficiency should be boiler's heat efficiency ride stove's heat
(5)Good quality, ideal composition of Paris, stable physical
Property due to the low temperature heat source, the plaster does not tend to be over calcined. Only if controlling the discharte gypsum and with less than 5% anhydrite. And the spare is all hemihydrates gypsum. This composition is very ideal and with stable physical property.
