    Phosphogypsum Waste Processing,stone crushing,mineral processing


    Rock crusher: is mainly used for processing crushed rock crushing equipment. Common rock crusher including: jaw crusher, impact crusher, cone crusher and so on.


    Small sand production line price


    Rock crusher is widely used in water and electricity, highway, artificial aggregate, crushing and other industries.


    Phosphogypsum Waste Processing Serious problem


    Phosphogypsum is a kind of solid waste produced in phosphoric acid production. The main component is calcium sulfate, and a large number of insoluble impurities. Phosphogypsum contains fluoride, free phosphoric acid, P2O5, phosphate and other impurities, that are the major factors caused water, air and soil pollution. Produce 1 ton of wet process phosphoric acid will produce about five tons of phosphogypsum. A lot of phosphogypsum stockpiled, not only encroached land resources, but also cause atmosphere, water and soil pollution by wind erosion and rain erosion.


    Solution


    Phosphogypsum is with high moisture, so it needs drying or calcination at first, and then be fed into the grinding mill. Transport phosphogypsum into the calciner for calcining by Vibrating Feeder. Then send calcined gypsum to Trapezium Grinder for grinding. The size of the final products can be adjusted according to different requirements.


    Applications


    Phosphogypsum is with the features of large production, wide applications. So its effective recycling draws more and more attention. Using customized grinding production line,


    Large and small perlite sand production line


    can grind phosphogypsum into different degrees of fineness, to meet different demands for further manufacture.
