Active, continuous belt control
With active control and guiding of the belts, main-tenance costs can be cut considerably. The belt guidingsystem protects vital parts of the conveyor frame fromdamage. Less wear on the belt increases life and reducescosts. A misaligned belt causes point loading of rollers.A frozen roller can slice a belt in minutes. A centered beltcauses less wear and fewer break-downs. This minimizesthe risk of costly, unscheduled repair stoppages and in-creases availability. Load and transfer point spillages arereduced with the Belt Conductor. The result is increasedprofits due to higher throughput. It is important to have
Trellex Belt Conductor is one of many conveyor compo-nents available from Metso for reliable and economicconveying. Wear caused by misalignment can prema-turely put a conveyor out of operation. Loading pointmisalignment, side winds, rain/snow and uneven absorp-tion of heat from the sun, just to mention a few exam-ples, can interfere with the operation of conveyors. Thisis where our Belt Conductor enters the scene. This beltguiding system can prolong the life of a conveyor andimprove reliability under severe conditions. The result islower costs and increased availability.
Align your belts and boost profitability

a good working environment. A belt guiding systemfrom Metso contributes to a better working environmentand reduces the cost for cleanup.
Adjustable to various belt widths and types
Trellex Belt Conductor is easily adjusted to suit variousbelt widths. The medium duty model is suitable for beltwidths between 500 and 1200 mm (20" and 48"). Forwider belts an extra long axle must be used. Our BeltConductor can be installed on most types of belts. Thesensitivity can easily be altered by changing the anglebetween control arms.
Easy to install
Trellex Belt Conductor features a simple design for fastand easy installation, ensuring minimum downtime. Forsimple installation, the angle between the arms has beenpreset to fit most conveyor belt types. The Belt Conduc-tor is an efficient solution to your belt alignment prob-lem, and is designed to work under severe conditionswith a minimum of moving parts.

Trellex Medium Duty Belt Conductor
A centered belt is one precondition if the sealing sys-tem at the loading point is to work effectively. Reducingspillage increases revenue and provides a better work environment. The Belt Conductor is mounted on thereturn run of the belt and provides active restraint andconstant control of the belt. This avoids damage to theedge of the belt and important parts of the frame. Theedge rollers of the Belt Conductor sense any mistrackingof the belt and the control roller centers the belt. Elimi-nated risk of pinching, combined with minimal friction,result in a virtually maintenance-free solution.

Trellex Conveyor Belt Guiding System
A belt entering the tail pulley, centered, leaves it centered! The
centering of a belt moving on the return side of a conveyor is easier
due to the lower belt tension. This is why the Trellex Belt Conductor
is installed on the return part of the conveyor, ahead of the tail
pull ey. This posit ion ensures that the belt is cente red when
reaching the loading point. This is very important to avoid problems with mistracking due to off-center loading. The Belt
Conductor is an active guiding system keeping the belt
automatically and continuously centered. Guide rollers are
mounted to control arms which sense lateral movement of thebelt and adjust the steering roller to guide the belt back on track.
Mistracking is automatically corrected by a minor adjustment of
the steering roller angle. This eliminates belt edge damage, which
frequently occurs when high force systems with fixed guide rollers
are used.
This is how Trellex Belt Conductor works
Trellex Heavy Duty Belt Conductor
This is based on the same basic design as the mediumduty model but more robust for heavier applications. TheHeavy Duty Belt Conductor is suitable for steel cord beltsand for belt speeds of more than 3.5 m/s. The larger thebelt and the higher the speed, the more quickly dam-age occurs and the higher the costs become. The HeavyDuty Belt Conductor provides great savings in the formof reduced wear and tear on the belt, rollers and con-veyor frame. It also increases availability by reducingthe risk of unplanned down time. Like the other models,it is easy to assemble and is practically maintenance-free.

Solving chronic manintenance problems
The greatest problems with mistracking belts normallyappear on reversing conveyors. Most methods used onconveyors running in one direction only do not work well in this situation. In fact the result might be the op-posite when belt direction switches. The Belt Conduc-tor takes care of a constantly recurring maintenanceproblem, reduces operating costs and increases con-veyor availability.

puts an end to mistracking on bi-directional conveyors
Less wear on conveyor parts
Mistracking belts cause damage to the belt edge, rollersand the conveyor frame. By reducing the belts’ lateralmovement the risk of damage is reduced and overalloperating economy is improved.
Aligned belts boost profitability
The best evidence of how well the Trellex Belt Conduc-
tor works is found at the tail pulley. Because the belt
moves from side to side, the pulley surface becomes
"polished" in a sense. After the Belt Conductor has been
installed, belt mistracking has been reduced and rust will
form within a couple of weeks.

The compact design makes it possible to install the Reversible Belt Conductor even on conveyors where space is limited.
The Reversible Belt Conductor is mounted on top of the belt on
the return run. The steering roller should be installed on the same
level as the rest of the return rollers to achieve correct contact
pressure. On short conveyors the Belt Conductor is normally installed half way between pulleys. On longer conveyors more

units may be required. Pairs of edge rollers detect the slightest
deviation from the ideal belt path. The linkage on either side tilts
the Belt Conductor and the steering roller pushes the belt edge
down, creating a force aimed towards the center-line of the belt
that guides it back on track.
Less spillage and reduced clean-up costs
Trellex Belt Conductor is constantly sensing and adjust-
ing the belt path, which leads to less spillage. The work
environment is improved and clean up cost is reduced.
By keeping the transported material on the belt, plant
throughput and profitability are improved.
Easy installation, minimal down-time
Metso has developed a Belt Conductor that is very easy
to install. The Belt Conductor is designed to handle well
under tough conditions. The Belt Conductor is adjust-
able for a wide variety of belt widths up to 1200 mm
(48”). For wider belts the only thing needed is a couple
of longer axles.
