Roll Mill

  • Pair of smooth metal rolls set in the same horizontal plane, mounted on a heavy structure
  • Provided with an arrangement for adjusting the distance between the rolls and regulating the pressure
  • To increase the shearing action, the rolls are usually operated at different speeds
  • Two roll mills are used primarily for preparing color pastes for inks, paints, and coatings.
  • Rubber products and pastes are compounded in batch roll mills as they provide extremely high localized shear.
  • Continuous mills for mixing pastes contain three to five horizontal rolls.
