Metso has presented a redesigned Nordberg CVB inclined circular motion screen, the latest development in cost-efficient screening technology. The name of the screening range remains the same, but the design has been renewed to include more features.

Smart Solutions for Safer and Faster Maintenance

The new Nordberg CVB screen offers a comfortable space between the decks; 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 also is 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, according to the manufacturer.

Less Downtime

The vibrator, structural design and wear protection of a screen are the three areas most likely to cause serious trouble. Metso has paid extra attention to all of them.

• MV vibrators

The Nordberg CVB screen is fitted with the Metso MV modular vibrator, which features a dust-proof cartridge design. 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 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 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. An example of an upgrade option is Trellex 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 to 22 degrees, enabling screening efficiency for all types of applications such as primary, technical and final screening.
