Traclag slidable rubber pulley lagging

for belt conveyors

Metso Outotec’s Traclag slidable rubber lagging is a quick replaceable lagging system suitable for a wide range of applications. This system is specially designed to increase conveyor availability as it is applied directly onto the pulley shell. The slide lagging pads slide into retainers welded into the pulley shell. New pads can be easily replaced without removing the pulley from the conveyor.

About Metso Outotec Traclag slidable rubber lagging

Application

Metso Outotec’s Traclag slidable rubber lagging is used in applications that require an easy installation and operation. Benefits include the application and removal of the lagging without removing the drum from the conveyor system and no need to sandblast pulley shell before application, slidable lagging products are recommended for the mining, quarry grain and concrete industries. Slide lagging kits are supplied pre-cut to pulley size for fast and easy installation.

Design

Our Traclag slidable lagging has specially designed compound elastomers moulded under high pressure to heavy duty steel plates, which are shaped and cut to fit each pulley diameter and face. The plates slide in and out of steel retainers which are welded to the pulley shell.

Slide lagging are all moulded under pressure to the steel plates with no lagging failure from loss of adhesion or separation between the steel and the compound. The slide lagging steel plates are 135 mm wide to ensure easy handling and application with 5 mm of exposed steel at each side for clipping retainers. Rubber slide lagging is 15 mm thick, pad length is 1687 mm and can be cut and bent to suit the pulley size. Slide lagging kits are supplied pre-cut to pulley size for fast and easy installation or can be supplied in full lengths.

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.
Do NOT store together with fuels, lubricants, acids, disinfectants, solvents or other chemicals.
Allow 24 hours before use when lagging is removed from cold storage.
Shelf life for cold vulcanizing lagging: 3 years.
(Stored covered out of sunlight UV and away from ozone generating equipment)

Calculate your need:

There are two ways of applying slide laggings:

The butt seam method which is the most economic option. Pads are cut to fit the pulley face width and the remaining ends of each cut pad are used butted together. Pieces shorter than 100 mm should be discarded.

The full width method when no butt seams are desired. Each pad row is provided with full face width pads that have no butt seams. 


Example pulley diameter 600 mm & face width 1000 mm.
Butt seam method:
1. Number of rows =
pulley diameter x 3,14
160
(160 = 135 mm pad width + 25 mm allowance for retainer.)
x = (600 x 3,14)/160
= 11,775
Round down to closest whole number -> 11.
2. Multiply the number of rows of pads by the pulley face width,
divide with 1687 (full length pad in mm)
11 x 1000/1687= 6,5
Round up to closest whole number -> 7 full length pads
required.

Full width method:
1. Same as 1. above.
2. Calculate how many full width sections you can get from a
standard size pad.
1687/1000= 1,7
Round down to closest whole number -> 1.
3. Divide number of rows with how many full widths you can get
out of one pad.
11/1= 11 -> 11 full length pads required.

Retainers:
Double retainer= (Face width + 50 mm*) x numbers of rows / Length of retainer = 5,7 -> 6pcs

**Retainer length/Row = Face width + 25mm on each side

Single retainer= (Face width + 50mm**) x 2 / Length of retainer = 1,03 = 2 pcs

**Always 2
