Brief About the Harp Screen and its Applications

The harp screen, also known as the piano wire screen, is formed with a single face of highly tensioned wires. The harp screen’s wires are connected at both ends and feature a metal hook. The long cables are tightly clasped to each other at a great distance by a transverse band in the harp screen. This procedure ensures that the screen also produces its discordant frequency in addition to the screening device’s vibrations. This prevents screen meshes from being clogged or plugged.

The wires, either straight or crimped, are protected with some wide-area cross supports in harp screens. This allows every wire to become stimulated due to the item to be screened and the screening machine’s force. The extra vibrations generated throughout the procedure aid in reducing the possibility of sticking, blindness, or pegging.

A Harp screen is a screen panel indicated for difficult-to-screen materials and those that stick or blind conventional wire, particularly for wedge-shaped and damp cloths.

Isevier Harp

They have crimped screen wires on the Isevier harp. The cables are placed in square meshes one after the other. The crimped wires are joined at specific spacings by wires or PU bindings to achieve screen stability.

  • Serpa-Flex-Harps is another name for this species.
  • Stainless steel and spring steel are the materials used.
  • Stainless steel or spring steel cross connectors, PU
  • Application Maximum temperature: 800°C
  • The maximum screen width is 2500 mm.

Iseveno Harp

The wires on the Iseveno harp are alternately crimped and straight. Horizontally, this configuration is crimped to the screen level. These crimps of wire and the straight wire make a triangle screen opening. Cross binding with plastic bindings is then used to put the wires at a specific spacing. The separation distance can, however, be modified based on the demand.

  • Veno-Flex-Harps is an alternate name for Veno-Flex-Harps.
  • Stainless steel and spring steel are the materials used.
  • Stainless steel or spring steel cross connectors, PU
  • Application Maximum temperature: 800°C
  • The maximum screen width is 2500 mm.

N-Harps

Crimped and smooth longitudinal wires are used to make N-harps. THESE WIRES ARE FIXED AT A SPECIFIC DISTANCE through PU bindings or wires built by these long screen apertures.

  • Harpa-Flex-Harps is an alternate name for Harpa-Flex-Harps.
  • Stainless steel and spring steel are the materials used.
  • Stainless steel or spring steel cross connectors, PU
  • The temperature of application: maximum 800 C
  • The ultimate screen width is 2500 mm.

Advantages of Harp Screens

  • High productivity
  • Cross harps have increased production. It produces more tonnes per hour per square foot of screen than any other screen surface.
  • Harp screens allow for screening of moist and stuck materials that would be difficult to screen with a woven product.
  • Harp screens enable screening at narrower gaps than would be achievable otherwise.
  • Materials that are difficult to screen are screened.
  • Effect of self-cleaning

Application field of Harp Screens

  • Sandpits
  • Quarries
  • Gravel Pits
  • Mines
  • Recycling
  • Asphalt production

Conclusion

A harp screen can screen even the most delicate and complex materials. They are only available with tensioning folds. Harp screens are required for the screen’s proper functionality. Polyurethane wire or braids are also included in the screen, which helps to improve the screen’s efficiency and longevity. Harp screen gives you the best possible results in each situation. In this article, you got to know the advantages and applications so far. You can do make a more profound and precise search for the knowledge.
