Whatever your process requirements, Metso has the right solution – from sturdy feeders and scalpers to efficient inclined or horizontal classifying screens. Just name your application, and Metso’s professionals will find the most productive and cost-effective vibrating equipment for you.
Circular motion for better screening efficiency
CVB screens have a simple and robust design. A single shaft line consists of two MV modular vibrators connected through a shaft. As the shaft line is positioned at the center of gravity, a circular motion results on all points on the screen. Combined with slope angle, this circular motion provides good screening efficiency for all types of screening applications.
Product range
Standard slope angle is 18°, however, this can be modified if needed. Adjustable counterweights allow for stroke adjustment to suit the application requirements.
To accept primary material (up to 16 inches /400 mm), the CVB Primary model has a reinforced top deck fitted with flat panels (rubber or steel plate) and the side plates are extended upwards. Screen settings are adjusted accordingly for primary applications (increased stroke). Available in 2 or 3 or 4 deck configurations, CVB’s have a wide application capability.
Designed for reliability, ease of maintenance
CVB screens consist of modular components assembled with huck bolts (side plates, deck frames, MV modular vibrators). The huck bolt fastening system has proven to be a very safe and reliable method of fixing. There is ample space between decks for easier screen media replacement. It is also possible to gain access to screen media through the back of the screen.
MV Mechanism – safer, faster, easier
CVB screens feature the modular vibrating (MV) mechanism. This innovative feature is a cartridge design that maximizes uptime and ease of maintenance. It eliminates time-consuming servicing and replacement of bearings and other components common to most vibrating equipment. The long bearing life offered with four bearings per shaft line allows for a single drive system on most screens, in contrast to the traditional dual-shaft, four bearing screens.
Screen decks
The CVB can be set up for crowned decks to accept side tensioned screen media – of any type (woven wire mesh, anti-clogging wire cloth, rubber, polyurethane, etc.) or flat decks to accept modular synthetic media. The top deck of the CVB Primary version is fitted with flat bolted panels (rubber or steel plates).
