Metso Introduces Redesigned Nordberg CVB Inclined Circular Motion Screen

Metso is proud to present a redesigned Nordberg CVB inclined circular motion screen, the latest development in cost-efficient screening technology. The name of the acclaimed screening range remains the same, but the design has been renewed to include more features and generate even more benefits to our customers who are always aiming for maximum plant availability, lower operational cost, and more flexibility to better follow market trends.

Smart solutions for safer and faster maintenance
Safe working environment is a priority to Metso. Therefore, an industry-leading safety level is a standard feature in Metso equipment. That's why the new Nordberg CVB screen offers the most comfortable space between the decks in the category of inclined circular motion screens. A large space lowers the risk for injuries and makes the replacement of screening panels quicker.

To increase safety even further, the Nordberg CVB screen is also equipped with coil spring covers to minimize the risk of pinching accidents, and rubber stabilizers, high-safety belt guards and one centralized, conveniently located greasing manifold.

In addition, the wear protection liners are bolted on, which makes them safe, easy and fast to replace unlike the glued rubber liners found in similar screens on the market.

Less downtime thanks to a durable design

At Metso, we know that the vibrator, structural design and wear protection of a screen are the three areas most likely to cause serious trouble. That's why we've paid extra attention to all of them.

  • MV vibrators
    The Nordberg CVB screen is fitted with the renowned Metso MV Modular Vibrator, which features the most advanced, dust-proof cartridge design ever seen in a vibrator. Because of their dual bearings, the MV vibrators are very durable.
  • Structural design
    The weld-free side plates of Nordberg CVB ensure optimal durability and a high stress tolerance. The screen also includes weld-free cross members that drastically increase its lifetime under fatigue and allow for more tonnage.
  • Maintenance-friendly wear protection
    The feedbox and discharge spouts of the screen are protected with Metso's Trellex(TM) modular wear and impact resistance rubber linings. Easy maintenance and quick replacement of screening media, wear liners and spare parts let you maximize uptime and improve the profitability of your production.

Flexible performance
To make the new Nordberg CVB screen fit for several applications its robust standard deck frames are preconfigured to handle both modular and tension screening media with minimal interruption and can easily be converted to handle the Metso screening media of choice. A great example of an upgrade option is Trellex(TM) LS modular screening media, which is optimized for Metso screens and thus helps guarantee total screening performance.

For added flexibility, the trunnion spring brackets allow adjustable installation angle from 12-22°, enabling excellent screening efficiency for all types of applications such as primary, technical and final screening.

The new Nordberg CVB screen complements Metso's well-known and highly recognized offering of crushers, feeders and screens, and is available in selected markets from February 2014.
