Wedge Wire Screen

Wedge Wire Screens

Wedge wire screens from Multotec are manufactured and distributed as high quality wedge wire screen panels, and are custom-manufactured to suit specific screens, machines and applications. Making use of a wide range of apertures and profiles on the various wedge wire screen sizes, these screens are specifically designed to reduce pegging in difficult applications.

Featuring:

  • Screen longevity unaffected by processing coarse & acidic minerals
  • Withstands most corrosive & abrasive applications on the market
  • High grade stainless steel wedge wire screen filters on demand
  • Grade 430 stainless steel construction for abrasive applications
  • Grades 304 & 316 stainless steel construction for corrosive applications

To ensure the ultimate solution for our clients, screen fastening systems and a range of screen accessories form part of Multotec’s offering.

International mining giants trust Multotec’s screens to provide high wear resistance and achieve high drainage throughputs in some of the world’s harshest operating conditions.

Customised screens

As wedge wire screen manufacturers, Multotec ensures its wedge wire screen products are available in a wide range of apertures and profiles. This certifies that we provide the highest wear resistance according to your specific application requirements. Our unique manufacturing capability enables us to customise screen panels to suit both wedge wire screen machines and applications.

The profiles of the longitudinal wires determine the shape and size of the downward slot opening and affects the extent to which slots remain open. The combination of materials used in the construction of our wedge wire screens make them ideal for all high abrasion and corrosion mineral processing equipment requirements.

We also offer a uniquely designed wedge wire sieve bend screen along with a wide range of application-specific profiles. The sieve bends are manufactured in 430 stainless steel to provide abrasion resistance, although 304 or 316 stainless steel is used for corrosive applications.

Wedge Wire Screen advantages

As wedge wire screen manufacturers, managing the entire screen lifecycle from design and installation to monitoring of equipment is a service offered by Multotec. This is conducted remotely from their premises to help deliver optimum screening equipment performance.

These tailored screens provide the following advantages:

  • Machine spot-welded for high strength throughout
  • High abrasion and corrosion resistance
  • Precise sizing is maintained
  • Maximised open area drainage
  • High release angles

To ensure our customers benefit from these advantages, mineral processing screens are manufactured and quality tested in-house at Multotec’s 43 000 m2 facility in Johannesburg. Where possible, wedge wire products are manufactured and tested in the country of order.

Screens for specific applications

  • Abrasive applications: Screen panels used in abrasive applications are manufactured from Grade 430 stainless steel. This is ferritic steel with no nickel, creating high abrasion resistance and good weldability.

    Extreme abrasive application surfaces are hard-chromed on request.
     
  • Corrosive applications: Screen panels are constructed from Grade 304 stainless steel. This steel is made up of 18% chromium and 8% nickel making it durable and long-lasting.

    Grade 316 stainless steel for highly corrosive applications is provided on request.

Frequently asked questions

What is a wedge wire screen?

A wedge wire screen, also called a wedge screen, is a multi-functional screen that provides clogging (pegging) resistance. Also called profile wire (or v wire screen filter in some industries), it consists of a metal mesh element encased in a profile and is used in in screening, filtration, dehydration and desliming applications.

Characterised by wedge wire mesh with high strength, high rigidity and high load carrying capacity, they are manufactured in a variety of shapes and often custom-manufactured to suit specific design requirements.

What is a profile wire?

As these screen products rely on profiles for their effectiveness, they are also called a profile wire screen and, depending on the industry, a profile wire is called a tri-wire.

It can be constructed of various materials, but in the mineral processing industry they are usually manufactured from durable stainless steel or 430 stainless steel. This ensures wire longevity, even in abrasive and corrosive environments.

What are wedge wire screen filters?

In the mineral processing industry, wedge wire filter screens need to withstand abrasive and corrosive applications. Both vibrating and static wedge wire screens can be used.

When selecting a wedge wire screen for your mineral processing applications, the following factors should be considered:

  • Does it offer precise, maintainable sizing?
  • Does the drainage area suit your exact requirements?
  • Does it provide sufficient abrasive & corrosion resistance?
  • Are the release angles appropriate for your application requirements?
  • Does its construction & arrangement facilitate minimal pegging?

As renowned wedge wire screen suppliers, Multotec will ensure that the above criteria meet your specific screening requirements. As a mineral processing equipment manufacturer, we also offer a wide range of apertures and profiles with our wedge wire screening solutions.
