RF-B-VT-30T

RF-B-VT-30T Filter Belt: Specialized Double-Layer Belt for Gypsum Filtration, FGD Systems and Mining

High-Precision Filtration for Gypsum and Flue Gas Desulphurization (FGD)

The RF-B-VT-30T filter belt is a high‑performance technical textile designed for demanding separation processes such as gypsum filtration, flue gas desulphurization (FGD) and a variety of mining applications. Engineered for use on horizontal vacuum filters, this belt delivers reliable, consistent and controlled filtration where precise moisture control and fine particle retention are essential.

Its double-layer Twill construction ensures superior cake support and structural stability, making it ideal for filtration processes that require exacting performance under continuous vacuum pressure.

Key Features and Benefits of the RF-B-VT-30T Filter Belt

• Double-Layer (DL) Twill Weave for Enhanced Filtration Control:
  The unique DL/Twill construction combines a fine filtration layer with a strong support layer. This structure provides:
  • excellent solids retention
  • reliable filtrate clarity
  • improved vacuum distribution on the filter table
  • reduced risk of mechanical deformation

• Optimized for FGD and Gypsum Separation:
  Gypsum filtration in Flue Gas Desulphurization systems requires belts with:
  • precise moisture control
  • high resistance to chemical exposure
  • consistent filter cake strength
  The RF-B-VT-30T meets all of these requirements, making it a trusted solution for coal power plants and industrial desulphurization units.

• Medium Crease Resistance with High Structural Stability:
  The belt’s construction ensures resistance against creasing and folding, reducing premature wear and ensuring long-term stable performance on horizontal vacuum filters.

• Low Air Permeability for Controlled Filtrate Flow:
  With an air permeability of 240 l/m²/s, the RF-B-VT-30T is designed for applications where controlled drainage, fine solids retention and precise vacuum performance are crucial. This low-flow profile is ideal for gypsum filtration and fine mineral separation.

• Durable PET Construction:
  Manufactured from Polyester (PET) in both warp and weft, the belt withstands mechanical stress, chemical exposure from desulphurization processes and the abrasive conditions found in mining environments.

• Reduced Cake Cracking and Improved Moisture Profiles:
  Thanks to its double-layer design and Twill structure, the belt provides stable support for the filter cake, reducing cracking and ensuring consistent moisture distribution.

• Multiple Seam Options:
  Available seam types include:
  • Stainless steel Clipper
  • Woven endless seam
  • Additional options on request
