Method for reducing water content of phosphogypsum retarder finished product
The invention discloses a method for reducing the water content of a phosphogypsum retarder finished product. The method comprises the following steps: S1, reducing the water content of phosphogypsum;S2, increasing the conversion rate of the crystal transformation reaction; S3, controlling the content of water attached to the retarder discharged from a kettle; S4, increasing the cooling rate of the retarder discharged from the kettle: additionally arranging an axial fan on a finished product belt for cooling; arranging a drum screen is additionally on a finished product belt, and subjecting powdery finished products with high water content to scattering and cooling; storing the finished retarder in piles, and turning the piles by a forklift for cooling. According to the invention, the water content of the cement retarder can be controlled within an ideal interval in the production process, and the high-quality cement retarder is obtained.
本发明公开了一种降低磷石膏缓凝剂成品含水量的方法,包括以下步骤：S1、降低磷石膏含水量；S2、提高转晶反应转化率；S3、控制出釜缓凝剂附着水含量；S4、提高出釜缓凝剂降温速率:在成品皮带上加装轴流风扇降温；在成品皮带加装滚筒筛，将含水量高的粉状成品抛撒冷却；将成品缓凝剂分堆存放，通过铲车翻堆进行降温。本发明实现了水泥缓凝剂在生产中水分能控制在理想区间内，获得高品质的水泥缓凝剂。
