Trellex Conveyor Belt Guiding System
Trellex Belt Conductor provides automated supervision of conveyor belt centring thus relieving the staff of much of the time-consuming
manual supervision and adjusting.
Align your belts and boost profitability
Trellex Belt Conductor is one of many conveyor components available from Metso for reliable and economic
conveying. Wear caused by misalignment can prematurely put a conveyor out of operation. Loading point
misalignment, side winds, rain/snow and uneven absorption of heat from the sun, just to mention a few examples, can interfere with the operation of conveyors. This
is where our Belt Conductor enters the scene. This belt
guiding system can prolong the life of a conveyor and
improve reliability under severe conditions. The result is
lower costs and increased availability.
Active, continuous belt control
With active control and guiding of the belts, maintenance costs can be cut considerably. The belt guiding
system protects vital parts of the conveyor frame from
damage. Less wear on the belt increases life and reduces
costs. A misaligned belt causes point loading of rollers.
A frozen roller can slice a belt in minutes. A centered belt
causes less wear and fewer break-downs. This minimizes
the risk of costly, unscheduled repair stoppages and increases availability. Load and transfer point spillages are
reduced with the Belt Conductor. The result is increased
profits due to higher throughput. It is important to have
a good working environment. A belt guiding system
from Metso contributes to a better working environment
and reduces the cost for cleanup.
Adjustable to various belt widths and types
Trellex Belt Conductor is easily adjusted to suit various
belt widths. The medium duty model is suitable for belt
widths between 500 and 1200 mm (20" and 48"). For
wider belts an extra long axle must be used. Our Belt
Conductor can be installed on most types of belts. The
sensitivity can easily be altered by changing the angle
between control arms.
Easy to install
Trellex Belt Conductor features a simple design for fast
and easy installation, ensuring minimum downtime. For
simple installation, the angle between the arms has been
preset to fit most conveyor belt types. The Belt Conductor is an efficient solution to your belt alignment problem, and is designed to work under severe conditions
with a minimum of moving parts.

A centered belt is one precondition if the sealing system at the loading point is to work effectively. Reducing
spillage increases revenue and provides a better work
environment. The Belt Conductor is mounted on the
return run of the belt and provides active restraint and
constant control of the belt. This avoids damage to the
edge of the belt and important parts of the frame. The
edge rollers of the Belt Conductor sense any mistracking
of the belt and the control roller centers the belt. Eliminated risk of pinching, combined with minimal friction,
result in a virtually maintenance-free solution.
This is based on the same basic design as the medium
duty model but more robust for heavier applications. The
Heavy Duty Belt Conductor is suitable for steel cord belts
and for belt speeds of more than 3.5 m/s. The larger the
belt and the higher the speed, the more quickly damage occurs and the higher the costs become. The Heavy
Duty Belt Conductor provides great savings in the form
of reduced wear and tear on the belt, rollers and conveyor frame. It also increases availability by reducing
the risk of unplanned down time. Like the other models,
it is easy to assemble and is practically maintenance-free.
This is how Trellex Belt Conductor works
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
pulley. This position ensures that the belt is centered 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 the
belt 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.
Trellex Reversible Belt Conductor
puts an end to mistracking on bi-directional conveyors
Solving chronic manintenance problems
Less wear on conveyor parts
The greatest problems with mistracking belts normally
appear on reversing conveyors. Most methods used on
conveyors running in one direction only do not work
well in this situation. In fact the result might be the opposite when belt direction switches. The Belt Conductor takes care of a constantly recurring maintenance
problem, reduces operating costs and increases conveyor availability.
Mistracking belts cause damage to the belt edge, rollers
and the conveyor frame. By reducing the belts’ lateral
movement the risk of damage is reduced and overall
operating economy is improved.
Aligned belts boost profitability
The best evidence of how well the Trellex Belt Conductor 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.
Trellex Conveyor Belt Guiding System
The compact design makes it possible to install the Reversible Belt Conductor even on conveyors where space is limited.
Less spillage and reduced clean-up costs
Easy installation, minimal down-time
Trellex Belt Conductor is constantly sensing and adjusting 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.
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 adjustable 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.
This is how Trellex Reversible Belt Conductor works
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.
Steering roller with Trellex Roller Sleeve
Steering roller with Trellex Roller Sleeve
Trellex Roller Sleeve is an elastic rubber sleeve that is recommended for use with the Belt Conductor steering
roller. The correction of the belt path is achieved by tilting the steering roller.
To get maximum steering effect the roller should have
a rubber coating to get the highest possible coefficient
of friction. The elasticity of the rubber counteracts the
build-up of material on the roller thus preventing misalignment. The rubber also protects the roller against
corrosion and wear, lengthening the service life and
reducing the risk of damage to the belt. Trellex Roller
Sleeve is simple to install using an adapter and compressed air.
Guide Roller snap-on sleeves
Trellex guide roller sleeves are made of our wear-resistant ESA78 polyurethane material, providing a long
service life. Wear on the shell of the roller is eliminated
and the life of the roller is extended. Damage to the belt
edge due to worn through edge rollers can be avoided.
The sleeves have a snap-on fixing, making installation
simple and quick.
Lubrication system

A complete lubrication kit
Maintenance is important. It is especially important in
the tough environment where these products are used.
That is why we have developed a lubrication system for
the Belt Conductor. It makes maintenance a lot easier,
extends the useful wear life and secures the function.
Installation is simple. The kit comes complete with
nipples, grease filled hoses and a block that should be
located in an easily accessable location on the conveyor
frame. By installing the lube kit, the work environment,
as well as safety conditions are greatly improved. At the
same time, the lubrication process is simplified.
