Application of Changjie filter press in phosphorite filtration field
1 . Market Research
Nowadays, in global phosphorite concentration and tailings field, membrane filter press, ceramic filter press and vertical filter press are adopted, the membrane filter press is in simple structure and low cost, the ceramic filter press is in high automation degree, while the above two kinds of filter press have some weaknesses like high moisture content and low processing capacity, the vertical filter press has high processing capacity, high automation degree and low moisture content, however, it also has weaknesses, for example ,the filter cloth is easily jammed, equipment failure rate and maintenance cost is high, and equipment is easy guniting.
2．Changjie advantages
Compared with membrane and ceramic filter press ,Changjie filter press have obvious advantages like: filter cake with low moisture content and high processing capacity rate per unit.
When compared with vertical filter press, Changjie high efficient filter press has three big advantages :
1）Keep the same moisture content rate with the world famous brand
2）The Changjie filter press unit maximum processing capacity is two times of vertical filter press.
3）Based on the same processing scale, the purchase price and running costs are far more less than the vertical filter press.
