Rotary Vacuum Disc Filters, also known as Sector Disc Filters – or Disc Filter Saveall machines in paper mills – provide excellent filtration area in the smallest footprint. Several discs stand in front of one another, connected to a center barrel and rotating through the slurry, open air, and the discharge zone.
Each disc is comprised of sectors, shaped like a slice of pizza. Each sector is either grooved or made of punch plate to allow liquid to pass through a cloth bag, into the sector, and out the center barrel. Both sides of each disc filter slurry simultaneously.
Like the Rotary Vacuum Drum Filter, a Disc Vacuum Filter pulls slurry from a tank under the center barrel of the filter. A solid cake forms on both sides of the disc surface while submerged. As the disc rotates out of the slurry tank, the sector continues pulling vacuum, allowing the cake to dry.
