Gypsum is a kind of monoclinic mineral ,whose main chemical component is calcium sulfate (CaSO4) hydrate. Gypsum is a widely used industrial materials and building materials, before which, we should use Gypsum Powder Processing Machine to process it into Powder. It can be used for cement retarder, gypsum building products, model making, medical food additives, sulfuric acid production, paper filler, paint fillers.For gypsum ore, it is widely existed in the world, the existed molecular formula includes: CaSO4, CaSO4.0.5H2O, CaSO4.2H2O,CaSO4.αH2O,CaSO4.βH2O, the difference is inner crystal water, but the application and function is quite different.
Stefan Liu, gypsum processing sales engineer of Shanghai Clirik Machinery company, who has many years experience for gypsum processing , up to now, he has clients in Turkey, USA, Germany and Oman.
The Gypsum Powder Processing Line step normally includes: crushing→calcining→grinding→packing, you can choose to calcine first , then grind , then you need use kiln, which is the most clients’ choice , since it is more easier to control temperature , so it is very popular in the world. Another way is grinding first , then use boiler to calcine it , less clients choose this one because not easy to control qualified finished product.
Different temperature , different output product of Gypsum Powder Processing Machine:
170-190 degrees:CaSO4.2H2O changed to CaSO4.0.5H2O, powder used for construction painting.
320-360 degree:CaSO4.0.5H2O changed to CaSO4,but this gypsum easy to absorb water.
450-750 degree:this CaSO4 not easy to soluble in water, ,the powder used for cement retarder.
