Mining, Quarrying & Bulk Materials Coating & Repair Services

Sliding bulk material wears through chute walls, hopper throats, silo interiors, and mill liners, and it hits hardest where the flow changes direction and impact concentrates. Once the plate thins you are on a clock toward a hole and an unscheduled stop. We line those surfaces with cold-applied ceramic-filled coatings, sized to the particle and the flow path, building thickness back where the wear is worst. The same approach handles cyclones and separators, where swirling particle-laden gas erodes cone walls and vortex finders until capture efficiency drops. The lining goes on inside the maintenance window. No welding, no plate fabrication. The transfer point recoats and the structure goes back into service, and no new section is ever cut in. That stretches plate life between changeouts and keeps the wear concentrated in a renewable layer instead of the host steel.

Conveyor belts take gouges, rips, and worn top covers, and the damage lets cargo escape and spread along the line until the belt is scrapped or the run stops. Rubber linings on chutes, hoppers, and slurry equipment strip off the same way, exposing bare steel to fast metal loss. Pulling a belt for splicing costs downtime the schedule cannot absorb, and sending a part out for re-lining costs the same time. We rebuild the damaged belt area cold with a flexible elastomer that bonds to the existing rubber, so the line returns to service with no splice and no belt replacement. Rubber linings get recoated and rebuilt in place on the structure as well, which renews abrasion protection without removing the part. The repair flexes and wears with the surface it sits on, and that is what keeps it bonded under impact.

Abrasive slurry erodes pump impellers, casings, agitators, and mixer blades, pulling the unit off its head curve and dropping efficiency long before the bearings give out. Wear plates and bars in chutes and crushers lose thickness to impact and sliding abrasion, then sit loose against an irregular backing. Steel shims leave only point contact, and the plate distorts inside a shift. We rebuild eroded vane and casing geometry and overcoat it with an erosion-resistant ceramic layer, so the pump returns to its rated profile with no weld heat and no rebalancing. On wear plates we rebuild the worn face, then bed the plate to full bearing with a cold-cure compound poured to fill the gap. The plate seats flat and carries load across its whole area, and it lasts longer between changeouts because nothing is riding on a high spot.

Bulk sites run on overhead cranes and elevated access, and both turn hazardous as they wear. Steel shimming under crane rails leaves point contact that fatigues the rail and the supporting structure under heavy wheel loads. Walkways, stair treads, and platform decks lose slip resistance to spilled fines, oil tracking, and worn aggregate, which raises fall risk in exactly the spots crews stand to work. We pour a cold-cure chocking compound that beds the crane rail across its full contact area and absorbs shock, so the track carries heavy-lift loads with no machining of the support. On access surfaces we apply safety-grip coatings to floors, stairs, ramps, and platforms, and they reopen to foot traffic the same shift. The outcome across the plant is the same. More material moves between outages, with fewer emergency stops, and equipment holds its dimension and its footing under load. Our crew stays on call when a transfer point or belt fails between shifts.
