Hot Vulcanised lagging application involves the chemical cross-linking of five reactive layers during the autoclave curing process. To achieve the
In November 2017 a major iron ore port facility in the Pilbara decided to replace the ceramic lagging on a
Spare pulleys are held so that in the event that an operational pulley requires replacement this can be done quickly
Catastrophic lagging failure due to debonding occurred within two weeks of installation and operation of the pulley, resulting in a
Lagging can be of good quality and application can be correct, but lagging can still fail and does. Everything seems right but the lagging still doesn’t perform to expectations. So why does this happen? It’s because the lagging selection is not right for the application.
Elastotec extreme diamond rubber lagging is designed for drive and non drive pulleys that require extended service life.
At Elastotec, we engineer lagging solutions that keep conveyors running. Here are some causes of lagging failure.
Elastotec Direct Bond Ceramic Lagging - application system designed to improve adhesion consistency, reduce lead times, reduce glue wastage and labour time.
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.
Elastotec Slide Lagging can be speciﬁed when there is a requirement for:
The Elastotec Slide Lagging range includes abrasion resistant rubber in natural (NAT) and FRAS and rubber backed ceramic in natural and FRAS.
Elastotec Slide Lagging is suitable for low tension applications under 100kN where a fabric conveyor belt is used.
Elastotec Slide 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, Slide 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.
Elastotec Slide Lagging steel plates are 135mm wide to ensure easy handling and application and it is 15mm thick. Slide Lagging pads are available in 1687mm length as standard but complete installation packages cut to size can be supplied. Pads are shaped to meet each pulley diameter. Designed for direct application to the pulley. The plates slide in and out of special retainers which are securely welded to the pulley shell.
Elastotec Slide 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.
Elastotec slide lagging designs include rubber slide lagging and ceramic slide lagging all moulded under pressure to the steel plates with no lagging failure from loss of adhesion or separation between the steel and the compound. Elastotec Slide Lagging steel plates are 135mm wide to ensure easy handling and application with 5mm of exposed steel at each side for clipping retainers. Rubber Slide Lagging is 15mm thick and ceramic slide lagging is 17mm thick. Pad length is 1687mm and can be cut and bent to suit the pulley size.

Slide lagging is inventoried in standard factory produced lengths to minimise stock keeping. There are two ways of applying slide lagging and this will affect the way it should be ordered.
This method is designed to be 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. Some pad rows are provided with full face width pads and some are provided with pad sections that make up the full face width.
Use the 1687mm pads to make up the pieces for the different rows. Pieces shorter than 100mm should be discarded. The number of 1687mm pads required for butt seam application for most common pulley diameters can be obtained from the table below or use the formula presented.
This method provides no vertical butt seams. Each pad row is provided with full face width pads that have no butt seams.
When no butt seams are desired, the number of full length pads required will depend entirely on the pulley size and the quantity of face width pad lengths that can be cut from one standard length pad.
The number of 1687mm pads required for full width method application for most common pulley diameters can be obtained from the table below or use the formula presented.
