Rolling filter conveyor

Rolling filter conveyor|Bunri is a specialized manufacturer of equipment that separates and discharges sludge and chips from grinding and cutting

Rolling filter conveyor AL
Rolling filter conveyor ALL
#30 Rolling filter conveyor SKA

Conveyor with punching filter that does not require backwashing.
The filter is automatically cleaned, reducing maintenance load.
Optimum for cutting chip processing of non-magnetic materials.


  • The punching filter captures cutting chips.
  • The punching filter is always in contact with the scraping board and rotates to prevent clogging.
  • No backwashing is required, so no mist is generated, which helps improve the environment in the factory.
  • The chip discharge port of the conveyor has a structure that drains liquid, which ensures that chips are drained before being discharged.This processing reduces the load to carry out coolant (means that coolant is discharged together with chips).
  • This product does not use any consumables such as cartridge filters or paper filters, so no industrial waste is generated.

Features of 3 Type


  • Uses the punching filter that is more rigid than the mesh filter.


  • Uses a punching filter with higher rigidity than AL to apply to sturdy chips.


  • Rolling filter conveyor for machining center #30.
  • Optimum for automatic discharge of net basket (manual scraping system).Chips are automatically discharged from the manual scraping system (net basket tank).
  • This product is also subject to consideration for its space-saving layout.


  1. The dirty liquid flows onto the conveyor.
  2. The dirty liquid is filtered as it passes through the rotating punching filter, and the clean liquid is sent from the inside of the punching filter to the outside of the main body.
  3. Chips captured in the punching filter are scraped off by the scraping board and settle on the bottom of the conveyor.
  4. Chips that have settled on the bottom of the conveyor are conveyed by the scraper.
  5. Chips are temporarily stored in the conveyor outlet, drained, and then discharged.
