РЕОЛОГИЧЕСКИЕ ХАРАКТЕРИСТИКИ СУСПЕНЗИЙ В ПРОЦЕССАХ КИСЛОТНОЙ ПЕРЕРАБОТКИ ФОСФОРИТА ПОЛПИНСКОГО МЕСТОРОЖДЕНИЯ
Аннотация
Ориентируясь на производство сложных удобрений азотнокислотным разложением полпинского фосфорита, исследована реология суспензий на стадиях разложения, аммонизации и смешения с калийсодержащим компонентом. Показано влияние исходной концентрации кислоты, мольного отношения аммиак/фосфорная кислота, соотношения Ж/Т, хлорида калия на вязкость полученных суспензий. Получены зависимости вязкости исследуемых суспензий от скорости сдвига для вышеперечисленных стадий. Показана технологическая целесообразность азотнокислотной переработки фосфорита Полпинского месторождения на NP- и NPK-удобрения.
