PRODUCT DESCRIPTION
Our Mining Hopper is engineered to withstand extreme abrasion and impact in demanding mining and bulk material transportation applications. Constructed from high-strength steel Q345B (EN 10025 S355JR equivalent) and reinforced with NM400 wear-resistant lining plates (Hardox® 400 equivalent), this hopper delivers exceptional durability while ensuring easy maintenance through its innovative modular design.
Key Features
- Dual-Material Construction:
- Structural Frame: Q345B steel provides superior load-bearing capacity and structural stability.
- Wear-Resistant Liner: NM400 hardened steel (400HBW hardness) protects critical contact areas, offering 3-5× longer service life compared to standard liners.
- Smart Modular Design:
- Bolt-on liner attachment system enables quick replacement without welding or specialized tools.
- Precisely machined screw holes ensure perfect alignment during liner installation.
- Optimized Geometry:
- 5m×5m×7.5m dimensions engineered for high-volume material flow with anti-clogging profile.
- 30°-45° slope angles (customizable) to match specific material characteristics.
- Advanced Manufacturing:
1. Precision laser cutting ensures ±1mm dimensional accuracy.
2. CNC press brake forms complex geometries with <0.5° angular tolerance.
3. Robotic welding (MAG process) guarantees full-penetration joints.
4. Hot-dip galvanized surface (standard) provides 80μm zinc coating for corrosion resistance.
5. In order to suppress the dust generated when the ore is dumped, we can cover the top of the hopper with a rubber grille, which has a good dust suppression effect.
