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 MAL

Conveyor that supports both magnetic and non-magnetic materials with a combination of magnet and punching filter.
Optimum for those who process both magnetic and non-magnetic materials using a single machine tool.


  • A single machine is suitable for chips of both magnetic materials and non-magnetic materials.
  • The magnet installed on the bottom of the conveyor captures magnetic chips.
  • The punching filter captures non-magnetic chips.
  • The punching filter is automatically cleaned by constantly rotating in contact with the scraping board, preventing it from becoming clogged.
  • 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.

  1. The dirty liquid flows onto the conveyor.
  2. Magnetic chips are captured by the magnet installed on the bottom of the conveyor.
  3. The dirty liquid is filtered when it passes through the rotating punching filter.The resultant clean liquid flows from the inside of the punching filter to the tank.
  4. Chips captured in the punching filter are scraped off by the scraping board and settle on the bottom of the conveyor.
  5. Magnetic chips captured by the magnet on the bottom of the conveyor and chips that have settled on the bottom of the conveyor are conveyed by the scraper.
  6. Chips are temporarily stored in the conveyor outlet, drained, and then discharged.
