Enhanced screening efficiency

Metso presents a high-energy elliptical motion horizontal screen – the Metso ES. It delivers up to 25 % more screening capacity compared to a conventional screen of the same size (Fig.). The Metso ES is available in selected markets since the end of May 2013, and fits well together with the other crushers, feeders and screens as a part of the company’s commitment to offer total crushing and screening solutions.

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 Metso ES performs excellently in any application with high requirements on screening accuracy – even in difficult screening conditions. Letting screens stand down for maintenance too frequently and for too long makes it hard to reach maximum profitability. That is why the Metso ES features an robust deck frame design, with no welding along the cross member sections to achieve lasting performance. The weld-free side plates ensure optimal durability and a high stress tolerance. The huck-bolted design guarantees perfect and homogeneous assembling conditions. There are no mechanical timing devices, gears, belts or oil leakage, which together with the reliable grease lubrication system simply keeps downtime and maintenance to a minimum.

The up to 50 % bigger space between the decks compared to similar flat screens means easier, safer and more comfortable access for maintenance. The Metso ES is equipped with coil spring covers to minimize the risk of pinching accidents, rubber stabilizers, high-safety belt guards and one centralized, conveniently located greasing manifold. Furthermore, the gearless mechanism concept reduces noise. The feedbox, discharge spout and cardan shafts of the screen feature TrellexTM modular wear and impact resistance rubber linings as standard protection. Because TrellexTM products, such as replaceable modular cross beam protection and TrellexTM LS modular screening media, are optimized for Metso screens, they are excellent and easily available upgrade options for the Metso ES. The robust 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 Metso media of choice.
