Slide Lagging

Elastotec Slide Lagging is a quick replaceable lagging system that has been designed to service 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.

Elastotec Slide Lagging can be speciﬁed when there is a requirement for:

Easy installation
Quick lagging replacement
Increase productivity

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.

Description

Application

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.

Key features and benefits

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.

Design

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.

Ordering Slide Lagging for a specific 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.

1. The butt seam method

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.

Example pulley diameter 600mm face width 1000mm

Multiply the pulley diameter by 3.14 and divide this by 160mm (135mm pad width + 25mm allowance for retainer) Diam mm x 3.14 / 160 mm. Round down to the closest whole number.
Example:
Pulley 600mm diam (600mm x 3.14) / 160mm = 11 rows.
Multiply the number of rows of pads by the pulley face width Number of pads x pulley face width (mm)
Example:
Pulley 1000mm face width 11 x 1000mm = 11000mm
Divide by 1687mm to determine the quantity of
full length pads needed. Round up to the next full length.
Total length required (mm) / Pad length (mm)
Example:
Pulley 11000mm / 1687mm = 6.5 pads
or 7 full length pads required.

2. The full width method

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.

Example pulley diameter 600mm face width 1000mm

Multiply the pulley diameter by 3.14 and divide this by 160mm (135mm pad width + 25mm allowance for retainer)
Diam mm x 3.14 / 160mm.
Round down to the closest whole number.
Example:
Pulley 600mm diam (600mm x 3.14) / 160mm = 11 rows.
Calculate how many full width sections you can get from a standard size pad. Divide the standard pad length by the pulley face width.
1687mm / 1000mm = 1.7
Round down to the closest whole number. This means that you cannot get more than 1 full row length pad from each standard pad.
Divide the amount of rows by the amount of full widths you can get out of one pad.
Example:
Pulley 11 / 1 = 11 full length pads required.
