Method for producing building gypsum powder from ardealite
The invention relates to a method for producing building gypsum powder from ardealite, which comprises the following steps: carrying out cyclone separation on ardealite slurry by a cyclone to obtain an overflow product and an underflow product; and filtering the overflow product to obtain a filter cake, and drying and calcining to obtain the building gypsum powder. By controlling reasonable particle size grading, the building gypsum prepared from the ardealite with lower quality also has higher strength, and the recycling rate of ardealite can be increased. The method is simple in process operation and low in calcination temperature, and does not generate waste gas and waste water in the production process.
本发明涉及一种磷石膏生产建筑石膏粉的方法，包括以下过程：磷石膏浆料经旋流器旋流分离，得到溢流产物和底流产物；将溢流产物过滤得到滤饼，经干燥、煅烧得到建筑石膏粉。本发明通过控制合理的粒径级配，使得通过较低品质的磷石膏制备的建筑石膏也具有较高的强度，能够提高磷石膏的回收利用率。并且本发明的方法工艺操作简单，煅烧温度低，在生产过程中不产生废气废水。
