ABSTRACT OF THE DISCLOSURE An improved rotary vacuum filter for producing filtration blanks or what may be termed pellets from slurries, especially for example, iron ore slurries. Known rotary filters utilize spiked deflecting rollers to remove iron ore agglomerates from interstices in a lattice-like belt. The use of a spiked deflecting roller necessitates the use of a metal belt which is difficult to produce since the belt must be sufficiently flexible to both pass around the deflecting roller and lie sealingly against the surface of a vacuum drum without permitting entry of outside air. This problem is over- come by the present invention which provides a vacuum filter whereby dehydrated iron ore agglomerates are easily released undamaged from the belt without impairing the suction effect produced by the drum. The rotary vacuum filter according to the present invention comprises a filter drum adapted to rotate about a horizontal axis while partly immersed in a filter trough filled with slurry, the filter drum is provided with a filter lining and a suction area, a forming belt, divided like a lattice, lies against the filter lining over the entire suction area of the drum and is adapted to rotate therewith, the forming belt extends from the drum over a deflecting roller arranged at a distance from the drum, the deflecting roller having a diameter smaller than a diameter of the drum, the belt adapted to be lifted off the said drum at an end of the suction area by means of the deflecting roller and being returned thereto before being immersed in the filter trough, the lattice forming belt having walls made of resiliently flexible material, interstices in the lattice for holding filtration blanks, said interstices being tapered conically towards a surface of the belt lying against the filter drum whereby filtration blanks are removed from the interstices by squeezing action as the belt passes around the deflecting roller.
