摘要
通过对我国首家磷矿重介质选厂花果树矿选矿厂的技术改造,引进煤炭选矿中广泛应用的重介质三产品旋流器,以全粒级不分级入选,在较高分选密度(2.88～2.90)下,对微差比重矿物分离获得成功.经对常用的旋流器进行改造内置高耐磨材料,从而极大地减少了运行成本.完善了介质控制、回收与净化系统,有效地减少了介质污染、密度变化、矿介分离的不稳定性,确保工业化正常生产,并形成了120万t/a的洁净生产规模,对同类矿的选别起到了良好的引领作用.
Three-products heavy-medium cyclone which is applied in coal concentration widely was introduced in transformation of the first phosphate heavy-media separation concentrator in China.Separation of slight gravity difference minerals was got ahead in high separation density（2.88～2.90）without classifying.Operation costs was decreased greatly by promotion of high wear-resistant materials built-in common heavy-medium cyclone.The medium controlling,recycling and purification systems was improved.Medium pollution,density change,instability of separation of minerals and medium was reduced effectively.Normal production and industrialization was ensured,and a 1.2 million t/a of clean production scale was formed to play a good leading role in the same type mineral processing.
