What are the Rotary Vacuum Drum Filters?

The rotary drum vacuum filters, a workhorse of the chemical process industry for many years, has been designed for long life and easy maintenance.   These filters involve half of the drum being submerged in the slurry and the other half above it. The Filter Cloth or belt winds around the drum, and as the drum rotates, the slurry is sucked into the cloth.  As the drum rotates, the cake is dried using vacuum pressure on the exposed area, and the cake is formed. The dried cake is discharged as the drum rotates.

Our range of Rotary Vacuum Drum Filter Cloths

• Our wide range of woven and non-woven media allows you to balance throughput, cake discharge, and long-life.

• High particle retention, bursting and tearing strength, and abrasion resistance of the fabric besides chemical and thermal compatibility are important. Besides, abrasion resistance is required as the process of removal of the dried cake involves scraping.

• Our quality Filter Cloth withstands the rigorous scraping process used to remove the dried cake.

• We often recommend a double-layered fabric to ensure the longevity of the filter cloth and better separation. Hence, we also offer a knitted nylon backing fabric that can be used underneath the top cloth to provide a cushion and stability for the cloth as it moves through the Rotary Drum process

• Innovative agitator rake design ensures solids remain in suspension and avoids
  sediment in the system tank for better materials distribution

• Wide range of choices for drum material to suit process demand– polypropylene, carbon steel (unlined or rubber-lined), stainless steel, as well as other materials
