Chute & Hopper Erosion Lining

The challenge

Transfer chutes, hoppers, and a slurry pump wore through fast at the high-impact and high-velocity points. The steel thinned, holes opened, and material started leaking onto the structure below. Each failure forced an unplanned shutdown, and the rebuild interval kept getting shorter. The plant needed the wear faces to last longer between repairs.

Our approach

We assess each component to separate sliding abrasion from direct impact, because the two wear patterns call for different protection. We blast the substrate, rebuild the thinned and holed steel back to profile, and line the wear faces with an impact- or abrasion-resistant composite. Where the part flexes or sees repeated impact, we apply a cold-applied elastomer instead. The work is matched to the actual wear so the new surface holds up where the old steel failed.

1. Assess wear patternWe inspect the chutes, hoppers, and pump to identify whether each face fails by sliding abrasion or direct impact.
2. Surface prepWe blast the steel to a clean, profiled surface so the rebuild and lining bond properly.
3. Rebuild worn steelWe fill holes and rebuild the thinned sections back to their original profile.
4. Line the wear facesWe line each face with an impact- or abrasion-resistant composite, or a cold-applied elastomer where flexibility matters.
5. Return to serviceWe cure and inspect the lined components, then hand them back ready to run.
