About Metso Outotec's Trellex® pulley bar rubber lagging

Application

Metso Outotec’s Trellex pulley bar is used in applications that require an easy installation and operation. Benefits include the application and removal of the lagging without removing the drum or belt from the conveyor system.

Design

Trellex pulley bar is made of hardwearing rubber and molded to an aluminium profile, this product has the perfect combination of elasticity and rigidity. This gives a superior ability to handle internal wear. The pattern also naturally eliminates water from the surface of the lagging as the pulley rotates.

Storage room for lagging must be cool, dry and kept clean.
Protect the lagging from dust, water etc. with suitable coverings.
Avoid storage places near sources of ozone generating equipment.
UV light can damage the product – protect product against direct sunlight and strong artificial light.
Do NOT store outside.

Allow 24 hours before use when lagging is removed from cold storage.
Shelf life for lagging: 3 years.
(Stored covered out of sunlight UV and away from ozone generating equipment)

Use this formula to determine if pulley bars can be used:
F = P
h x D x B
P = power (kW)
h = belt speed (m/s)
D = pulley diameter (m)
B = pulley width (m)
F should not exceed 130.

 

Shape is designed to suit all pulley diameters:

Installation

Hole centers on the drum, CC = 114 mm (4.5"):

Hole diameter 7.4 mm (0.29") for M8 self tapping screws:

 

Recommended tightening torque 25 Nm (19 lbf/ft):


Never install a piece that is shorter than 140 mm (5.5") and never use fewer than two screws:


Standard distance between Pulleybars is 35 mm. At belt speed >1.5m/s the distance between the pulley bars can be as little as 3 mm:

To avoid high noise level at belt speed >1.5 m/s we recommend installation as alternative 2
