Sintered metal mesh filter disc plates are the disc shape filter elements made of sintered wire mesh screen and support plate or frame. Sintered mesh filter disc can be disc plate assembly or monoblock. The sintered wire mesh can be welded with the frame plate sections. Then sections are assembled with bolts as a disc plate assembly. While in monoblock, the sintered wire mesh is whether welded or sintered with the whole disc support plate frame then welded with flange as disc assembly.
Sintered mesh filter disc for agitated nutsche filter / dryer ( ANF or ANFD )
Sintered metal mesh filer disc plate is most used in agitated nutsche filter / dryer, as the bottom filter screen. The disc plate catch the solids and form the filter cake, while the liquid is passed through and flow out. In other applications, the filter disc may used as air diffuser. The air flow through the sintered mesh and dry or motivate the solids on the disc.
Sintered mesh filter disc for chromatography column
Another important application of the sintered metal mesh disc plate is large scale chromatography column. On both the top and bottom of the column, there are totally two pieces of sintered mesh disc, one is for distribution, another is for support bed and filtration. The sintered mesh disc is also called chromatography frits by some column supplier.
Sintered mesh filter disc for explosive proof and flame arrest
Sintered mesh filter disc is good filter element to protect devices like detector, instrument, sensor from not only unwanted particles but also explosion and flame. The multi-layer porous structure stops the particles, disperses the flame and absorbs the energy. The sintered mesh let only the cooled and clean air / gas pass the filter disc.To precisely control the diameter of the diameter, we use laser or EDM cutting to cut the filter disc from the sintered wire mesh sheet.
Sintered mesh filter disc plate for extractor
Sintered mesh filter disc is the filter media for particulates and absorbents removal in extraction filtration process. The filter disc plate can be a bare sintered mesh, or sintered mesh welded with double tri-clamp fitting ( spool shape filter). Typical micron ratings are 1 micron, 5 micron and 10 micron.
Customization of the sintered metal mesh filter disc
Our micron rating options: 0.5 1 2 5 10 15 20 25 30 40 50 100 150 200 μm. Others on request.
Disc diameter is up to 1150 mm for monoblock without welding seam, and 3000 mm for disc assembly.
316L (1.4404) stainless steel is the mostly chosen material for the filter disc. Hastelloy C276, Hastelloy C22 are among the best choice for most challenging corrosive working conditions. Other exotic materials are also available as request, such as 310S, 904L, Monel 400, Inconel 625, etc.
