Description of Desulfurization Gypsum Powder Production Line
Production line of chemical gypsum powder: β building-specific gypsum powder
Chemical gypsum powder refers to industrial products formed in the process of industrial production, such as desulfurized gypsum, phosphogypsum, fluorgypsum, lemon gypsum etc. Material features: surface water is more than 20%; relatively unstable composition;
Production process for β building-specific gypsum powder
It adopts the two-step calcination production process which involves material pre-drying and combustion of furnace in fluid bed. Put the raw material on the loader and ship it from the stock dump to the hopper. Convey the material uniformly to the rotary dryer through thrasher and belt conveyer (The heat source hereof comes from the coal hot air furnace.) The material, after being discharged, shall be transferred by the powder conveying equipment to the vertical furnace in fluid bed for calcination (The heat source hereof comes from the thermal oil furnace.) The material, after the calcination process, shall be put into the ball grinder for modification and cooling and then be optimized and transferred to the finished product and packing warehouse.
Features of Desulfurization Gypsum Powder Production Line:
1. Simple structure, small floor space
2. Free of moving parts, low operation cost
3. Because of the thorough fluidization in the production process, the calcined gypsum is of a relatively ideal phase composition, and with stable product quality.
