These conical discs are core spare parts of the disc stack separator. Stacked with fixed gaps, they greatly expand settling area and shorten sedimentation distance, improving starch-protein separation efficiency under centrifugal force. Suitable for DPF/DPJ445, DPF/DPJ450, DPF/DPJ530, DPJ/DPF550, DPJ/ DPF800 series separators and Concentrators. Widely used in starch production lines. Custom sizes available.
