Metso’s latest high-energy elliptical motion horizontal screen, the model ES, is claimed to provide increased uptime and safer maintenance, while delivering up to 25% more screening capacity compared with a conventional screen of the same size.
The two unbalanced shaft lines in the Metso ES rotate in opposite directions, generating a high-energy elliptical motion with a self-synchronization design. The ES also features a robust deck frame design, with no welding along the cross-member sections. The weld-free side plates ensure optimal durability and a high stress tolerance, and the huck-bolted design guarantees accurate assembling conditions. There are no mechanical timing devices, gears, belts or oil leakage, which together with the reliable grease lubrication system, keeps downtime and maintenance to a minimum. The unit also offers up to 50% more space between the decks compared with similar flat screens, for easier, safer and more comfortable access for maintenance. The Metso ES is equipped with coil spring covers, rubber stabilizers, high-safety belt guards and one centralized, conveniently located greasing manifold. The feedbox, discharge spout and cardan shafts of the screen feature Trellex modular wear- and impact-resistant rubber linings as standard protection. The standard deck frame of the screen is preconfigured to handle both modular and tension screening media with minimal interruption and can be easily converted to handle the media of choice.
