Each nozzle is equipped with multiple air outlets, which can freely adjust different wind directions of each nozzle, so that the moisture content error of the same gypsum board in different parts does not exceed 1%Forced dehumidification by fan is conducive to the drying of gypsum board.When adjusting the temperature of the dryer, the cooling and heating adjustment reaction is rapid.The hot blast stove automatically adjusts the coal feeding amount according to the flue gas temperature, with high thermal efficiency.

If the flue gas desulfurization gypsum and coal powder from power plants are not treated in a timely and reasonable manner, a large area of land will be utilized, and even unnecessary secondary pollution will be brought to the environment. Desulfurization gypsum from power plants has the characteristics of high taste and small particles. However, with the widespread application of gypsum method and limestone/wet lime in thermal power plants in China, the production of desulfurization gypsum has rapidly increased due to its by-products.

This method is still widely used in the domestic ceramic industry.Pressure steaming method for frying pasteThis method first preheats the raw Plaster with a block size of 25-50mm after coarse crushing in hot air at 60 ℃, and then places it in a pressure cooker for 5-7 hours with saturated superheated steam at 1,3 atmospheric pressure (125 ℃). Then, hot dry gas at 200 ℃ is introduced until hot dry gas is discharged, resulting in a vapor pressure of hemihydrate Plaster.

Phosphogypsum is a by-product of ammonium phosphate production in phosphate fertilizer enterprises, mainly containing impurities such as fluoride, phosphorus pentoxide, and organic matter. It is highly acidic and has a pH value as low as 1.9. Research has shown that these harmful impurities are important factors leading to low comprehensive utilization rate of phosphogypsum.

Gypsum that has been overwhelmed and heated to cast off 75% of its water content material is acknowledged as plaster of Paris. When water is delivered to this first-class white powder, the ensuing cloth is without difficulty molded into any favored shape. Upon drying, the reconstituted gypsum regains its rock-like characteristics whilst preserving the favored shape.
