Belt conveyor components
The conveyance and transfer of material is a challenging and a demanding applications due to abrasion impact from the abrasive materials and / or the volume of material that are transferred on conveyor belts. Ceramic materials with high wear and impact resistance would be best 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 a Saint-Gobain ceramic products could solve would be loading skirts leaking, reduction of built up material in walkways that create safety hazard, reduce repair work on holes in head & tail chutes, etc. We work closely with customers’ process and operations team to co-develop solutions, to solve such frequently witnessed issues in the following equipments
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
