Self-cleaning Screens
Manufactured under the following
standards:
Certain materials have a tendency to adhere to the screen
• High-Resistance Steel: UNE-EN-10270-1:2012
(blinding), or become wedged (pegging), due to their humidity, plasticity or shape. This considerably reduces the production capacity of the screen and increases the downtime of the
machine.
To solve this problem we have self-cleaning screens with
crimped or straight wires, which vibrate independently from
one another, being excited by the vibration of the machine
ISO 8458-2:2002
DIN 17223
• Stainless Steel: UNE-EN-10088-3:2008
Stainless Steel Quality:
Austenitic: AISI-304 / EN-1.4301
AISI-316L / EN-1.4404
AISI-310 / EN-1.4845
Duplex: AISI-S32001 / EN-1.4482
and also by the weight of the material to be screened. This
allows a noticeable increase in production and a longer
lifespan of the meshes.
These meshes also offer a high percentage of screening surface, which makes them highly recommendable for improving
production capacity.
Doblonda®
Talleres Núñez’s self-cleaning screens are:
Doblonda®: This is our most popular self-cleaning screen,
having a very good combination of screening capacity and
precision.
Rectonda®: Is very similar to Doblonda® but its precision is
increased by adding a straight wire in between each of the
Rectonda®
crimped wires, which limits the movement of the crimped
wire, making it more precise but lowering its screening area.
Very effective under heavy loads and higher impact materials.
Doblorec®: Is a combination of the Doblonda® and Rectonda® screens, it adds a straight wire in between several
crimped wires.
Doblorec®
Medionda®: Is made with crimped wires placed parallel to
each other, this allows a very large screening area, but gives
lower precision. It is highly recommended for the removal of
fines.
Multirecta®: Also called harp screen or piano wire. It has
straight parallel wires, having the largest screening area with
low precision. It is mainly used in end tension mobile screens
Medionda®
to classify sands, gravel, and other dry materials.

Cross band Types
Self-cleaning screens are made with independent wires and cross band sections. These cross bands ensure the correct aperture
dimension and should be placed with regard to the wire diameter and the machine supports.
Polyurethane cross
bands
• Polyurethane cross bands, generally made with 80º Shore hardness
PU, withstand most of the aggregate screening applications, offering
great wear resistance and increasing the screen’s wear life.
• Used in all types of self-cleaning
screens.
Steel wire cross bands
• Used in applications where temperatures exceed 70ºC.
• Highly recommended for asphalt
plants.
• It is used in Doblonda® and Rectonda® screens.
Mobile cross band
• Mobile cross bands to fit any machine deck.
• Mainly used in mobile screening
plants.
• Only used on Multirecta® screens.

5.1
Self-cleaning Screen
Doblonda® Type
Characteristics
• 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

Self-cleaning Screen
Rectonda® Type
Characteristics
• 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 elon-

Self-cleaning Screen
Multirecta® Type
Characteristics
• 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
with PU coated metal rod
Characteristics
The self-cleaning effect is well known on tensioned selfcleaning 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.
