Advanced Solutions for Trommel Repair, Maintenance & Refurbishment
Trommel wear protection is critical for mining operations where SAG and Ball mills run continuously under extreme conditions. Without effective maintenance, these assets face downtime due to trommel repair, trommel liner replacement, and trommel refurbishment needs.
ShieldCrete® delivers pure polyurea coating systems designed to extend trommel life, reduce maintenance frequency, and improve operational efficiency.
Understanding Trommel Wear Challenges
Trommels are exposed to constant abrasion, impact, corrosion, and structural stress. Common issues include:
-
Abrasion: Coarse ore particles erode liners.
-
Impact Damage: High-velocity strikes at feed and discharge points.
-
Corrosion: High humidity and water exposure cause degradation.
-
Structural Fatigue: Loose bolts, liner detachment, and shell cracking.
How Climate Affects Trommel Lifespan
ShieldCrete’s experience in Australia, Papua New Guinea, and Africa shows that climate plays a key role in trommel lifespan:
-
Australia: High heat & dust accelerate liner fatigue.
-
Papua New Guinea: Humidity & rainfall increase corrosion risk.
-
Africa: Seasonal extremes require flexible, durable coatings.
Case Studies in Mining Operations
-
Western Australia SAG Mill Trommel: F15 AR increased service life from 18 months to 4+ years.
-
Papua New Guinea Gold Plant: Reduced liner changeouts by 40%.
-
Central Africa Copper Mine: Maintained coating integrity through seasonal extremes.
ShieldCrete’s Technical Advantage
Our ShieldPoly® F15 and F15 AR pure polyurea systems provide:
-
Abrasion resistance up to 30% higher than standard liners.
-
High elongation (>350%) for impact absorption.
-
Fast cure time (tack-free in 60 seconds).
-
Seamless membrane – no weak points.
-
Temperature tolerance from -40°C to +120°C.
For feeding conveyors, BeltShield™ CV repairs high-wear areas without replacing the full belt.
