Diefenbach SB Series side beam filter presses feature two side beams running the length of the machine that hold a pack of plates. These plates can be recessed or membrane plates, depending on the application. The plates feature a recessed area on both sides and are covered by a filter cloth.
During a filtration cycle, a moving head attached to the hydraulic cylinder presses the plates together so the recessed areas form chambers with the recessed area on the adjacent plates. The feed slurry is pumped into the filter press and fills the chambers. The liquid in the slurry passes through the filter cloths on the plates and exits the filter press through filtrate pipes.
Meanwhile, the solids are captured on the filter cloth as a filter cake. At the end of the filtration cycle, the plates open to discharge the solids as drip-free cakes. After a plate discharges a cake, it is shaken to remove residue that may remain on the filter cloth.
Once all the cakes are discharged, the plates are pressed together again and another filtration cycle begins.
