Commercial Trust & Engineering Warranty Charter
In mining procurement, trust is not requested: it is demonstrated. At SMAT Minerals, we transparently disclose what our Durango Central Warehouse inspection covers (Fiscal HQ at Mariano Salas #114): 1:1 dimensional assembly verification, industry standard drop-in fit assurance, and verified warehouse dispatch.
What We Test on Shop Bench
Every component dispatched undergoes rigorous dimensional and physical verification in our Durango facility prior to site shipment.
- Dynamic Balancing: ISO 1940 Grade G2.5 shop balanced to prevent bearing vibration.
- 1:1 Bolt Alignment: Template verification ensuring exact bolt-hole match with existing plant housings.
- Axial Clearance Check: Precise 0.75 mm clearance set to avoid internal recirculating erosion.
What Manufacturing Covers
Certified casting integrity backed by chemical spectrometry and ultrasonic non-destructive testing at partner foundries.
- ASTM A532 Alloy: High Chrome 27% Cr (>650 HB hardness) certified chemistry per batch.
- Casting Flaws: 100% replacement warranty against internal blowholes, porosity or shrinkage.
- Vulcanized Bond: High-resilience natural rubber with verified steel-substrate bonding.
When We Decline to Quote
Protecting your concentrator plant means knowing our operating limits. We never compromise safety for a blind sale.
- 1. Pumping / Cavitation: We decline quotes if suction NPSHa is severely deficient without piping redesign.
- 2. Flotation / Instability: We reject supply if excessive airflow rate destroys the quiescent mineral froth layer.
- 3. Filtration / Cloth Blinding: We decline standard filter cloths if ultrafine clay tailings lack conditioning.
Plant Commitment: Every spare part is covered by our 100% replacement warranty against manufacturing defects.
1:1 Dimensional Cross-Check & Physical Fit Verification Protocol
To safeguard assembly reliability in the field, every component dispatched from our Durango Central Warehouse is physically matched against standard frame dimensions (ANSI flanges, bolt circles, and shaft keyways) and checked for rotation concentricity and Brinell hardness (≥650 HB) prior to carrier loading.
