Universal lagging for a multitude of drum pulleys
Diamond lagging can be used on bend pulleys and take up pulleys, but is mainly intended for drive drums.
Applied using a cold bonding process, its symmetrical pattern offers excellent adhesion to the conveyor belt.
The diamond coating for conveyor belt drums is 8 to 15 mm thick.
Different types of diamond lagging for different applications
Several product qualities are available for this type of profile:
- Standard anti-abrasive: offers excellent resistance to wear over time.
- Black “anti-fat” nitrile rubber: reserved for applications in contact with vegetable, mineral and animal oils.
- ISO 284/340 specific rubber: this type of rubber has antistatic and self-extinguishing properties. This standard meets ATEX zone criteria.
- White nitrile: for applications requiring compliance with FDA and EU 1935/2004 food standards.
- Hot vulcanization: different types of diamond rubber can be supplied, such as blue nitrile (NBR) laggings.

Other profile types
Ceramics
The high-adhesion lagging
Effective in humid environments to prevent slipping on the conveyor belt.
Smooth
Protective lagging
For conveyor pulleys that don’t drive the belt, to extend their service life.
Slide Lag
For high tensile forces
Its elastomer composition gives drive or head pulleys high tensile strength.
Pulley bars
Anti-skid lagging for large drums
Ruggedly designed, the anti-skid bars are made of wear-resistant rubber for long life.
Griplag
For tough conditions
The Griplag prevents slippage and is self-cleaning, preventing material build-up and misalignment.
VARIOUS LAGGING AND PREPARATIONS
Hot vulcanization
Vulcanisation is a chemical process that gives the drum pulley lagging greater tensile strength, swelling, abrasion resistance and elasticity.
Cold rubberising
Cold rubber bonding is generally used on "classic" drum pulleys for rubber coatings with smooth, diamond-shaped ceramic inserts.
Special rubberizing
Coatings such as Slide Lag, Pulleybars or Griplag are applied to conveyor drums and conveyor pulleys by mechanical assembly.
Shot-blasting
All coated conveyor pulleys are shot-blasted for improved surface preparation. This preliminary work is essential for optimum adhesion to the conveyor belt pulley.
TECHNICAL SUPPORT IN DEFINING YOUR PRODUCTS
