The separation of solids and liquids has become a critical process as mining operations seek more efficient processing of valuable metals and methods to achieve the high purity requirements of end users, while meeting increasingly stringent environmental regulations.
Through decades of working closely with leading mining companies ,ECOGRACE Filtration has developed one of the broadest ranges of filtration products for mining applications. These products include press filter cloths, woven and spiral belts and dust bag filters - all optimized to meet the needs of mining applications.
ECOGRACE Filtration has been the recognized filtration supplier of filter cloths and belting to mining operations and their associated mineral processing plants for decades. With the ever-growing scale of operations and increasingly rigorous process requirements, we continuously develop new filtration solutions to meet your objectives .

Filter Cloth Replacement :
When using a filter press for separating liquid from solids, you need filter cloths that are in topcondition.When your filter press no longer forms a solid cake, it is time to replace filter cloth.
Monofilament /Multifilament filter cloth : have good air and water permeability.They have good ability to prevent the blocking in the fabrics and the filter cakes can be take off easily, very good filter precision and much longer working life .
