Treatment process of industrial waste phosphogypsum
The invention discloses an industrial waste phosphogypsum treatment process which comprises the following steps: grinding phosphogypsum for 10-15 minutes at the grinding rotating speed of 200-300 r/min; uniformly mixing phosphogypsum and quick lime at the mass ratio of quick lime to phosphogypsum being 1: (30-40); then carrying out aging treatment; adding water into the phosphogypsum, filtering and drying; grinding the phosphogypsum for 20-30 min at the grinding rotating speed of 400-500 r/min; and adding water, filtering and drying; grinding the phosphogypsum for 20-30 min at the grinding rotating speed of 400-500 r/min; and adding water, filtering and drying. The phosphogypsum can be treated, and the recycling problem of the phosphogypsum is solved. The phosphogypsum provided by the invention has excellent mechanical properties.
本发明公开了工业废磷石膏的处理工艺，包括：对磷石膏进行研磨处理，研磨转速为200‑300r/min，研磨时间为10‑15min；将磷石膏与生石灰混合均匀，生石灰与磷石膏的质量比为1:30‑40；之后进行陈化处理；向磷石膏中加入水，过滤，干燥；将磷石膏进行研磨处理，研磨转速为400‑500r/min，研磨时间为20‑30min；加入水，过滤，干燥；将磷石膏再次进行研磨处理，研磨转速为400‑500r/min，研磨时间为20‑30min；加入水，过滤，干燥。本发明可以实现对于磷石膏的处理，解决了对于磷石膏的回收利用问题。本发明的磷石膏具备优异的力学性能。
