Belt Conveyor Components

The conveyance and transfer of materials is a challenging and demanding process due to abrasion/impact from the abrasive materials and/or the volume of material that are transferred onto conveyor belts. Ceramic materials with high wear and impact resistance are preferred over traditional materials like AR steels, weld overlay, plastics, (ceramics imbedded in) urethanes and rubber to reduce overall down time due to maintenance and frequent change overs.

Typical issues that Saint-Gobain ceramic products solve would be: the loading skirts leaking, reduction of spills in walkways that create safety hazard, and the reduction of repair work in head & tail chutes caused by holes. We work closely with customers’ process and operation teams to co-develop solutions, to solve such frequently witnessed issues in the following equipment examples listed below.

Equipment Examples:

Head chute
Loading skirt
Transfer point
Dribble chute
Bins
Chutes
Diverters

Flop gates
Pulley lagging
Skirt boards
Transfer chutes
Hoppers
Silo cone bottoms
Spouting

Slurry Pump Components

Harsh Abrasive Slurry Environments are very demanding on internal pump components. Loss of head pressure, cavitation issues, are a few examples that cause a high volume of traditional wear part replacements. This makes the process expensive and creates a bottle neck in continuous production.

Our vast material and application expertise allows us to offer a wide range of products manufactured to complex engineered shapes and lining systems that can be adapted to your processes using these components listed below.
