Screening media tension systems

Trellex TCO is an all-round cloth designed primarily for final products of 4-100 mm.

Trellex TCO is made of T60 wear-resistant rubber and features special heat-treated cord reinforcement that facilitates tensioning and also maintains the proper tension without the need for continual adjustment. The reinforcement also reduces the degree of tensioning, which contributes to longer service life. Trellex TCO screen cloths are fitted with tension hooks as standard. For screen widths exceeding 1,300 mm, center hold-downs should be used. Trellex TCO is normally used for thicknesses of 5-50 mm.

All Trellex TCO are custom-made to fit any screen cross tension or longitudinal tension.

Trellex TCO-PU is a screen cloth made of highly wear-resistant polyurethane. It is designed specifically for use on longitudinally and transversely tensioned screens for screening in the medium and fine ranges.

The panels are especially suited to wet screening. They fit all vibrating screens in the same way as conventional rubber screen panels, so no modification to the support frame is needed. The configuration of each panel can be manufactured to suit your needs.

Apertures are either slotted or square. Precision-molded apertures ensure consistently accurate sizing. Reinforced by steel cables, Trellex TCO-PU is tensioned exactly as a wire mesh panel, eliminating the potential for elongation.

The Metso wire screening media system Trellex® PCL (PolyClean) enables you to screen your material efficiently, even in the most demanding conditions. Trellex PCL can screen feed that is damp and sticky or prone to pegging and produce a cleaner product. Combining the wear-resistance properties of polyurethane with the open area of wire media, Trellex® PCL provides increased wear life and capacity compared to classic wire.

Trellex® PCL has a flexible inner core that allows greater vibration of individual wires. This inhibits buildup of material over the screening surface, preventing blinding and increasing the efficiency. The flexible inner core is capped with a wear-resistant layer that maximizes the life of the media.

Complete range of opening, wire diameter, metal and weave types to provide you with the correct product for your application. Our extensive inventories allow us to supply you the correct product to your exact specifications.

Ultraloy wire has the optimum combination of strength, ductility and abrasion resistance. These properties combined with advanced manufacturing processes offers up to 30% increase in wear life. 

Astroloy is an extremely hard, abrasion and corrosion resistant metal. This metal excels when used in applications where the material is extremely abrasive and chemically corrosive. The smooth surface prevents material from adhering to it, making it ideal in applications where the material is damp and prone to blinding.

Metso offers wear parts with materials and designs optimized for each application. We work closely with our customers and carefully follow their process to make sure the media we supply is always optimized for current operating conditions. We can design and supply screening media for all types of screens – for Metso screens or competitor screens. Our wide product range, innovations, knowledge and experience make us unique. Our approach to wear parts design is focused on screening performance, availability and safety.
