Project

Chute & Hopper Erosion Lining

Worn chutes, hoppers, and slurry pumps rebuilt and lined with impact- or abrasion-resistant systems matched to the wear.

The challenge

What was failing

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.

Erosion protection applied to a high-velocity surface
Our approach

How AAS approaches it

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.

Assess wear pattern

We inspect the chutes, hoppers, and pump to identify whether each face fails by sliding abrasion or direct impact.

Surface prep

We blast the steel to a clean, profiled surface so the rebuild and lining bond properly.

Rebuild worn steel

We fill holes and rebuild the thinned sections back to their original profile.

Line the wear faces

We line each face with an impact- or abrasion-resistant composite, or a cold-applied elastomer where flexibility matters.

Return to service

We cure and inspect the lined components, then hand them back ready to run.

What you get back

The result

Worn steel rebuilt in place without replacing the chutes, hoppers, or pump housing
Wear faces lined and matched to the actual abrasion or impact pattern
Holes and material leaks sealed at the points that were failing
Longer interval between rebuilds, with fewer unplanned shutdowns
