Circular motion Inclined screensscreen range Metso PREMIER CVB seriesCVB™ screens Your versatile screening partner Inclined screen circular motion CVB Productive reliability ”When you need a versatile and durable partner in your screening process, Metso PREMIER CVB™ is the one to have.” 2 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 (3.0x7.3m). 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 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. Fatigue calculations 3 Environmental benefits 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! 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 4 not add-ons, but part of our standard offering. 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 pinching 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 Trellex LS modular screen media. Metso PREMIER CVB™ has extremely robust and uniquely designed deck frames that are preconfigured to handle both modular and side tension screening media that is easily interchangeable from one to the other. Coil spring covers Modular Metso design MV vibrator Reliability in operation Metso’s MV vibrator cuts downtime for replacement by half! While conventional designs require a dust free environment during replacement (to prevent contamination and consequent bearing failure), the MV vibrator solves this problem with a unique dust-proof cartridge design.
