The Tilting Pan Filter belongs to the top feed group and has found its main application in the phosphoric acid industry and, to some extent, in the washing of phosphate rock.
The operation of Tilting Pan Filters is based on a series of horizontal independent trapezoidal pans mounted on a circular supporting structure that rotates under vacuum during the filtration cycle and invert under blow to discharge the cake.
During filtration, the cake may be washed counter-currently, generally in three stages, while the mother and wash filtrates are flowing to separate vacuum receivers. After the final drying portion of the cycle the cake is discharged dry.
Following cake discharge the pans pass over radial manifolds with high impact jets that clean the cloth and dislodge any cake leftovers that remained on the pan's surface.
