Ore transport chutes and troughs
What it is
Ore transfer chutes and troughs in mineral processing plants receive coating in interchangeable cast PU parts. Absorb impact of falling ore, reduce wear on the structural substrate, reduce operational noise.
The PU technology applied here is typically anti-abrasion cast pu coating, selected for the combination of mechanical, chemical and processing properties suitable for the application. Specific formulations vary by equipment manufacturer or final integrator, but the base system has stable characteristics documented in technical literature and segment-specific standards.
Why it matters
For operators, contractors and heavy equipment suppliers in Oil, Gas and Mining, ore transport chutes and troughs is a decision where aggressive environment (salinity, abrasion, chemicals, extreme temperatures) quickly defeats standard materials. Equipment service life on offshore platform, refinery or iron-ore mine is a direct function of chosen materials — and replacing components in operation is expensive and risky.
Current drivers. Brazilian pre-salt (Petrobras and partners) operates in more aggressive environment than North Sea or Gulf of Mexico. Brazilian mining (Vale, CSN Mineração, AngloGold) has highly abrasive ore flows in 24/7 operation. Post-Brumadinho modernization in mining and decommissioning investment in Oil & Gas create structural replacement volumes. Abrasion and corrosion-resistant PU systems compete directly with vulcanized rubber and special steel in specific applications.
