shot blasting treatment For conveyor drums and pulleys

Pre-treatment for conveyor drum surface preparation

All coated drums are shot-blasted for better surface preparation. This preliminary work is essential if the rubber lining is to achieve optimum adhesion to the drum.

Shot blasting is a technique that consists of projecting microbeads onto the surface of an object using a shot blasting machine to modify its surface structure. This technique is used to improve the surface integrity and hardness of a material, and to improve adhesion between different adhesive layers.

Profile types

Diamond

The universal lagging

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

Ceramics

The high-adhesion lagging

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

Smooth

Protective lagging

For drums that don’t drive 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 and is 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 lagging protect the belt and significantly improve the conveyor’s overall performance, thus extending its service life.
They ensure that rollers and drums rotate smoothly 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.
