Drum Lagging
Drum Lagging
Drive Drums are lagged to provide traction to eliminate belt slip.
Drum Lagging is available in several options:
- Plain rubber 60 shore – for extra wear protection on tail drums & clean side snubs Plain 40 shore – for anti cake on dirty side snubs
- Diamond pattern rubber – will be sufficient for most applications
- Slide / Weld on steel & rubber strips – where space is limited
- Ceramic – where extra traction is required

Anti-Caking & Plain Lagging
Plain anti-caking lagging is a softer compound typically 40-50 shore hardness.
It has been developed to reduce material build up that damages belts and joints. It also reduces the build up of dirt on side drums that would otherwise easily influence tracking of belts.

Autoclaved Lagging
Autoclaved lagging is the preferred option for many installations. This is performed off site in an autoclave, this results in a rubber covering with a seamless finish and an unrivalled adhesion.
Advantages:
The drum face does not need to be in a good condition to achieve an excellent seamless finish Unrivalled adhesion
Any thickness of rubber can be installed
All most any profile can be achieved
Disadvantages:
With Autoclaved Lagging the Drum needs to be removed from site and returned a few days later.
Ceramic Lagging
Ceramic lagging is used when belt slippage is a problem and standard lagging will not suffice. Ceramic tiles made with a raised profile pattern are moulded into a rubber backing. These embed themselves in the underside of the belt which provides positive non-abrasive traction. the increased coefficient of friction provides 3x the purchase of rubber lagging.

Diamond Lagging
Diamond Lagging has become the recognised industry standard.
Advantages:
Relatively inexpensive
In most instances can be performed on site and in situ Available in different pattern
Disadvantages:
Re-scorable drum surface for good adhesion
Cannot be performed in wet or damp conditions on site Minimum curing time is 8 hours
Diamond Lagging
Slide Lagging
Slide lagging is used when access to the drum face is limited and conventional lagging cannot be adhered. Retainers are welded to the drum face and then rubber faced steel pads (curved to suit the drum face) are slid into the retainers.
