Способ получения гранулированного фосфогипса относится к промышленности строительных материалов. Гранулированный фосфогипс применяется в качестве регулятора сроков схватывания цемента и других вяжущих взамен природного гипсового камня. Сущность способа заключается в том, что сырьевую смесь, состоящую из фосфогипса и цементной пыли, подвергают прессованию и окатыванию, а затем поверхность гранул опудривают минеральным тонкодисперсным порошком, имеющим удельную поверхность 300 - 500 м2/кг. В качестве минерального порошка применяется пыль электрофильтров вращающихся цементных печей или зола-унос ТЭС. Этим достигается полная нейтрализация кислотных остатков, содержащихся в фосфогипсе, высокая начальная прочность гранул, улучшается их транспортабельность.The method of obtaining granulated phosphogypsum relates to the building materials industry. Granulated phosphogypsum is used as a regulator of the setting time of cement and other binders instead of natural gypsum stone. The essence of the method lies in the fact that the raw material mixture consisting of phosphogypsum and cement dust is pressed and rounded, and then the surface of the granules is powdered with mineral fine powder having a specific surface area of 300 - 500 m 2 / kg Electrostatic dust dust from rotating cement kilns or fly ash is used as a mineral powder. This is achieved by the complete neutralization of the acid residues contained in phosphogypsum, the high initial strength of the granules, and their transportability is improved.
