  5. ROTARY DRUM FILTERFilter characteristics Final dry zone Wash zone Blow and discharge zone Predry zone Dead zone Formation zone

  6. ROTARY DRUM FILTERFilter types • with grooved filter cloth or wire fixing

  7. ROTARY DRUM FILTERFilter types • Cake discharge: String Scraper/Wire Roller

  8. ROTARY DRUM FILTERFilter types • with belt discharge (run-off belt)

  9. ROTARY DRUM FILTERFilter types • Cake discharge Belt

  10. Rotary Drum Filter Filter Types • “Bird-Young” encapsulated filter

  11. ROTARY DRUM FILTERTypical use • Working conditions: • continuous de-watering of high solid content slurries requiring no or little washing • Slurries with solids that do not tend to settle rapidly • Filtrates that generally do not require a sharp separation between the mother and wash filtrates

  12. ROTARY DRUM FILTERTypical use • Industries: • Mineral ores such as alumina, coal, kaolin • Basic chemicals such as synthetic resins, waxes • Sweeteners and starch

  13. ROTARY DRUM FILTERCommon problems • Lifetime of the drum cover • Clogging / filtration performance • Belt tracking • Belt width

  14. ROTARY DRUM FILTERSefar Solution • choice of monofilaments and DLW • choice of polymers • suitable pore size and construction • standard rubber profiles available

  15. ROTARY DRUM FILTERSefar solution • special closures available • welding and stitching for extra wide drums

  16. ROTARY DRUM FILTERSefar solution • Sefar Filter Media • see selected samples and fabric sample book • Sefar Fabrication
