Metso PREMIER CVB™

Metso PREMIER CVB™ has one of the strongest
legacies in the industry of delivering dependable
screening performance in more than 2,000 screening
applications around the world.
The Metso PREMIER CVB™ have been developed on
this legacy and made even more robust and versatile
than ever before. An example of its enhanced
durability and reliability are the uniquely designed
deck frames that are more than 50% stronger versus
the traditional designs.
The uncompromised wear protection is standard and
the extensive selection of upgrade options and a new
smartly engineered trunnion solution are examples of
features that contribute to a unique, versatile, and cost
efficient screen to own and operate.
Versatile performance
Metso PREMIER CVB™ has shaft lines that
consist of two Metso MV vibrators connected
with a cardan shaft.
The shaft line is positioned at the center
of gravity resulting in a perfect circular
motion on all points of the screen.
Combined with an adjustable slope angle
from 12-22°, this circular motion gives very
good screening efficiency for all types of
applications such as primary, secondary, and
final screening. Adjustable counterweights
allow for easy stroke adjustment to optimize
performance specific to the application
requirements.
Metso PREMIER CVB™ is available in 2, 3 or
4 deck configurations and in a wide range of
screen sizes from 5x12ft (1.5x3.6m) to 10x24ft
(3.0 x7.3m).

Simply reliable
How did we come up with such a reliable,
all-around screen?
The Metso PREMIER CVB™ are the result of
FEA and fatigue calculations, combined with
extensive kinematic studies. Our R&D team
also carried out cross calculations along with
comparisons between CAD tools, theoretical
calculations, bench testing, and on-site tests.
The result is the most durable CVB
design ever. Specifically, there is no welding
along the cross member sections of the
screen, which prevent cracks from forming
along the beams. This reduces the risk of
fatigue stress, therefore, optimizing the
screens life.
In addition, Metso PREMIER CVB™ has
Frame Fatigue calculations
weld-free side plates, which increases the
screens durability and stress tolerance. Huck
bolting gives you superb and consistent
assembling, resulting in a robust and reliable
connection.
Total lowest cost
Size for size, Metso PREMIER CVB™ screens
are often the most economical screen in
terms of capital expenditure and power
consumption compared to other types of
screens such as horizontal screen etc.
Total lowest cost to operate has been one
of the main drivers in the development
process of the new Metso PREMIER CVB™. All
wear and spare parts have been
modularized and standardized in order to
offer our customers optimal cost and
availability. Material selection on wear liners
and spare parts are uncompromised. Metso
understands the importance of high quality
wear and spare parts for maximum screen
uptime.
Metso PREMIER CVB™ is designed to
deliver the total lowest cost to operate by
standardizing wear and spare parts, creating
high availability, which eliminates expensive
down time due to high cost customized
items with low availability.

Maintenance friendly
The most space between the decks on
the market is not the only thing that
contributes to the fact that Metso PREMIER
CVB™ is a very maintenance friendly screen.
The modular MV vibrators and cardan
shaft design are uniquely easy to replace. MV
vibrators have double the bearings versus
conventional designs, ensuring extended
bearing life. The equally balanced forces
ensure that there is not a bending moment
at the side plate along with lower stress
levels in the screen body. Thick, high quality
modular rubber liners at the feedbox,
discharge spouts, and cardan shaft, provide
optimal service life and are standard
features.
Easy maintenance and quick replacement
of screening media, wear liners, and spare
parts let you maximize uptime and improve
the profitability of your production.
Worker safety
Creating a safe working environment is one
of Metso’s top priorities. Safety solutions are
Environmental benets
Safe and convenient
Compared with other circular motion inclined screens, Metso PREMIER CVB™ offers
the most space between the decks. This makes it easier, safer and more
comfortable for operators during maintenance intervals.
More space between the decks is one of the most important features on a screen
to improve worker safety!
not add-ons, but part of our standard
oering. In this respect as in many others,
Metso PREMIER CVB™ comes out ahead of
the competition.
To give you a few concrete examples:
Metso PREMIER CVB™ is equipped with coil
spring covers to minimize the risk of pinch-
ing accidents; rubber stabilizers are provided
to reduce erratic movement during start up
and shut down, preconfigured to be
equipped with dust and noise protection,
V-belt drive equipped with safety guards,
and just one centralized conveniently
located greasing manifold.
Modular wear parts
The high availability of wear parts help
minimize both downtime and operational
costs. The feedbox, discharge spouts, and
cardan shaft covers come with Trellex™
modular wear and impact resistance rubber
liners as standard features.
We offer high quality, easily available
upgrade options. For example, replaceable
modular crossbeam protective covers and Coil spring covers
Trellex LS modular screen media.
Metso PREMIER CVB™ has extremely
robust and uniquely designed deck frames
that are preconfigured to handle both mod-
ular and side tension screening media that is
easily interchangeable from one to the other.
