METHOD AND DEVICE FOR CALCINATING PHOSPHOROUS PLASTER |
摘要 |
Method for calcining phosphogypsum or other moist synthetic gypsums comprises calcining the gypsum in a calcining unit (3) milling it post-calcining in a second reactor (6) and milling it again.The second milling step comprises fine milling and is carried out in the same reactor as the post-calcining step while feeding in a moist gas : Independent claims are included for calcination apparatus for use in carrying out the method; and an add-on reactor for calcination plant for carrying out the fine milling stage fitted with a turbomixer and a control unit for the feeding of moist gas which maintains a density in the reactor of at least 0.4 kg/m 2>. |
