Self-cleaning Screen Doblonda Type

  • The crimped wires form a square-shaped aperture, obtaining a precise and effective screening.

 

  • Its individual wires vibrate independently from one another, avoiding material build-up, pegging and blinding.

 

  • This type of screen is the most popular of the self-cleaning series, offering great screening capacity and precision.

Self-cleaning Screen Rectonda Type

  • It has a straight wire in between its crimped wires which maintains the correct aperture size under heavy loads and high impact material screening.

 

  • This more precise classification prevents wedging of elongated particles.

Self-cleaning Screen Doblorec Type

  • It is a combination of Doblonda® and Rectonda® screens.

 

  •  It is used when more precision is required at a maximum production output.

Self-cleaning Screen Medionda Type

  • It is a low precision screen but with a high production rate, making it perfect for removing fines.

 

  • It is used in small aperture sizes and in end tension decks.

Self-cleaning Screen Multirecta Type

  • The Multirecta® screens, normally called Harp screen or Piano wire, have straight parallel wires, separated with cross bands to obtain the correct aperture size.

 

  • Distances between these cross bands can be much higher than in the other self-cleaning screens.

 

  • Their high screening area is perfect for the screening of sand and gravel and offers very low resistance to the materials passing through, this gives them a long wear life.

 

  • They can be manufactured with mobile cross bands for easy installation on mobile screening plants.

Tension-free self-cleaning screen

The self-cleaning effect is well known on tensioned self- cleaning screens, on which the independent wires vibrate separately in order to avoid blinding, pegging and wedging of materials screened. But there are cases when machines do not have the tensioning system. For these cases Talleres Núñez has designed and developed the reinforced self-cleaning screens. This kind of screen maintains the self-cleaning effect without the need of being in tension. They have a rigid reinforcement that allows them to be attached to the deck or machine structure, either bolted down or pressed down with side plates.
