HOT VULCANIZING For conveyor drums and pulleys

Expertise for the lagging of every conveyor drum

Vulcanization is a chemical process by which the physical properties of the rubber/metal bond are improved. This gives the drum greater tensile strength, swelling resistance, abrasion resistance and elasticity.

The advantage is a seamless lagging, avoiding weak points. What’s more, the polymerization between the rubber and steel prevents any risk of delamination. These features make them ideal for high-temperature product transport applications.

Profile types

Diamond

The universal lagging

Used on bend pulley and take up pulley. It is also suitable for head drums.

Ceramics

The high-adhesion lagging

Effective in humid environments to prevent slipping on the conveyor belt.

Smooth

Protective lagging

For drums that do not entrain the belt, to extend their service life.

Slide Lag

For high tensile forces

Its elastomer composition gives head or drive drums 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 while being self-cleaning, preventing material build-up and misalignment.

The benefits of rubber lagging

Bonding systems that make installing drum rubber easy, fast and tailored to your needs.
The laggings protect the belt and significantly improve the conveyor’s overall performance, thus extending its service life.
They ensure that rollers and drums rotate smoothly and without clogging, thus maintaining and aligning the conveyor belt.
Rubberized pulleys protect the belt by reducing slippage between belt and drums.
They reduce the belt’s operating tension, thus reducing belt elongation.
They reduce conveyor noise and vibration.
