3 NUBA Screening Media desde Self-cleaning Screens Certain materials have a tendency to adhere to the screen (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 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. Manufactured under the following standards: High-Resistance Steel: UNE-EN :2012 ISO :2002 DIN Stainless Steel: UNE-EN :2008 Stainless Steel Quality: Austenitic: AISI-304 / EN AISI-316L / EN AISI-310 / EN Duplex: AISI-S32001 / EN These meshes also offer a high percentage of screening surface, which makes them highly recommendable for improving production capacity. NUBA Screening Media s self-cleaning screens are: Doblonda 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 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. Rectonda Doblorec : Is a combination of the Doblonda and Rectonda screens, it adds a straight wire in between several crimped wires. 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. Doblorec 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 to classify sands, gravel, and other dry materials. Medionda Multirecta 49

4 NUBA Screening Media dede 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. 50

5 NUBA Screening Media desde 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 series, offering great screening capacity and precision. d 5.2 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 elongated particles. d 51

6 NUBA Screening Media dede Self-cleaning Screen Doblorec Type Characteristics It is a combination of Doblonda and Rectonda screens. It is used when more precision is required at a maximum production output. d 5.4 Self-cleaning Screen Medionda Type Characteristics 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. d 52

7 NUBA Screening Media desde 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. d 5.6 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 NUBA Screening Media 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. 53
