Rotary Vacuum Drum Filters

Product Details:

Features:Rotary Vacuum Drum/Disc Filter more popularly known as Vacuum Filters or RVDF; The process is continous filtration of Slurries to separate solids & Liquids through a filter medium by Vacuum.Filter Medium is usually a mesh of Steel or Cloth or PP Mesh or Rare Earth deposition based on the type of Application. Vacuum Filtration can is manily achieved by three methods Rotary Vacuum Drum Filters, Rotary Vacuum Disc Filters and Rotary Vacuum Pan Filters.Selection of Type of Filter & its Filtration media is by proven similar experience or Test Work only.The process usually involves slurry adhering to the rotating surface when under vacuum, as the cycle progresses the cake remains on the surface while the Filtrate/liquid runs downstreams; later in the cycle the vacuum is cut-off to release the cake in discharge zone.The cycle continous in repeated manner ranging from 0.25 RPM to 8 RPM depending on Type and application of Vacuum filters

The Indofab Rotary Vacuum Drum Filter (RVDF) is a highly efficient continuous filtration system designed to handle slow-settling slurries with high solid concentrations.

The system utilizes a metallic, rotating drum partially submerged in a semi-circular trough (VAT) containing the slurry. Filtration occurs as the drum rotates: the submerged section uses a suction vacuum to pull liquid through the filter media, while simultaneously forming a solid filter cake. As the drum emerges from the slurry, the continued vacuum and atmospheric pressure work together to maximize cake dryness.

• Uniform Cake Quality: Each RVDF is equipped with unique swinging agitators located in the trough. This ensures the slurry is constantly and uniformly mixed, preventing lumping or patching and guaranteeing a consistent cake layer.

• Customization: Units are adaptable with application-specific features, including systems for cake washing, media cleaning, and specialized discharge scrapers.

• Flexibility: Indofab offers these filters in various sizes, designs, and Materials of Construction (MOC) to integrate seamlessly into diverse plant environments.

This technology is primarily applied for dewatering, clarification, or washing processes in critical sectors such as Mineral Beneficiation, Effluent Treatment, and the Food & Pharma industries.
