Wringers - Centrifuges

PRAB Wringer/CentrifugeDry Chips - Reclaim Fluid

PRAB's heavy-duty chip spinners use more than 600 g-force to reclaim up to 98 percent of valuable coolant and cutting oils from aluminum, brass, cast iron, steel, stainless steel and other metal chips so you can:

  • Reclaim fluids for recycle and reuse
  • Significantly reduce haul-away cost
  • Get more value from dry chips

The rotating bowl creates centrifugal force that drives the chips and fluid towards the bowl liner.

  Fluids are extracted through the bar screen and stored for reuse.

PRAB Gravity Discharge Wringer Equipment InteriorConventional gravity discharge (CD Series) models is available in 16-, 24- and 40-inch screen diameters (models 16CD, 24CD and 40CD). The conventional gravity discharge (CD) model of PRAB Wringers / Centrifuges utilizes an exclusive reversing feature to extend service life and minimize maintenance. When service is needed for wear items - such as screen and bowl - they are easily accessible and replaced.

The Model 16CD wringer is a component of the E-Series Chip Processing System, built to process low to medium volumes of wet machining scrap. Click here to learn more about the E-Series Chip Processing System.
