Industry operating characteristics
Impact loading, sliding material, dust and moisture change rapidly across transfer and processing equipment.
Industry applications
Mining & Bulk Materials
Wear protection for crushers, hoppers, chutes, conveyors, fans and pipelines handling abrasive bulk materials.
Typical process and equipment systems
Crushing, screening, storage, transfer, conveying and dust extraction create concentrated wear at transitions and direction changes.
Typical equipment
Operating environment and conditions
Environmental exposure
Abrasive particles and dust
Impact and sliding contact
Moisture and outdoor exposure
Operating conditions
High material throughput
Repeated start-stop and blockage clearing
Difficult access inside equipment
Why the problems form
Material size, hardness, velocity, impact angle and moisture determine whether impact, sliding abrasion or corrosion-assisted wear dominates.
Particle wear and erosion
Typical equipmentCrusher · chute · hopper · conveyor
Particle size, speed, impact angle and concentrated flow remove material unevenly.
Thinning, grooves and local perforation can disturb flow and shorten service intervals.
View solutionCondensation and under-film corrosion
Typical equipmentDust collector · outdoor conveyor · steelwork
Moisture collects at cold spots, welds, supports and poorly drained details.
Blistering, pitting and hidden corrosion can spread beyond the visible defect.
View solutionChemical-medium attack
Typical equipmentWet-processing pipe · slurry equipment
Identified acids, alkalis, salts or process liquids can penetrate incompatible or discontinuous films.
Softening, discoloration, loss of adhesion and substrate attack can develop around defects.
View solutionOperational impact
- Rapid local material loss
- Flow disturbance and blockage
- Frequent repair at transfer points
Protection objectives
- Map impact and sliding zones
- Match barrier toughness to the substrate
- Keep inspection and repair practical

What information is needed to review protection in Mining & Bulk Materials?
Provide the equipment location, substrate, medium, operating state, visible particle wear and erosion signs, access and maintenance constraints. The review must begin with the actual service condition.
Which Mining & Bulk Materials equipment should be inspected first?
Prioritise assets such as Silo and hopper · Bucket elevator · Chute · Dust collection equipment where exposure is concentrated, coating condition is changing or access is only available during shutdown.
Can an old coating be overcoated in Mining & Bulk Materials service?
Only after adhesion, contamination, moisture, defects and compatibility are assessed. Loose or chemically affected layers around particle wear and erosion zones must not be buried.
How should combined corrosion and wear be handled in Mining & Bulk Materials?
Map where each mechanism dominates, especially around particle wear and erosion areas, then define preparation and a compatible layered system for each zone.
How is application quality checked for Mining & Bulk Materials equipment?
Use traceable preparation records, environmental checks, coverage and defect inspection, confirmed hold points and the protection objective: map impact and sliding zones.
What should a maintenance plan for Mining & Bulk Materials include?
Record repeatable inspection locations on Silo and hopper · Bucket elevator · Chute · Dust collection equipment, changes at welds, edges and repairs, and correct local damage before it spreads beneath the surrounding system.
