Wear-Resistant, High-Performance sprocket wheel for Global Mining Operations
PRODUCT PARAMETERS
Description
Selection of sprocket wheel Materials
| Mine Environment | Best Material | Why It Wins |
|---|---|---|
| General Coal Conveyors | 42CrMo | Balanced strength & cost – ideal for most mines |
| High-Impact Ore Processing | 20CrMnTi | Highest tooth hardness – survives crushing cycles |
| Acidic/High-Humidity Mines | ZG40CrNiMo | Prevents corrosion – no rust in wet tunnels |
| Budget Projects | QT800-2 Ductile Iron | Low cost, high vibration damping |
1.Design
- Mine-Specific Parameters: Define tooth count, pitch, and diameter for mining conveyors, excavators, or hoists.
- Precision CAD Models: Strict tolerances and wear-resistant surface specs.
- Material Selection: Exclusive mining-grade alloys (42CrMo, 20CrMnTi, ZG40CrNiMo).
2.Forging Process
Defect Detection: Ultrasonic testing (UT) on all blanks.
Closed-Die Forging: Optimizes metal flow → 30% higher fatigue strength for mine vibrations.
3.Heat Treatment of sprocket wheel
Critical for mines: Prevents wear from abrasive ore/coal.
Core Hardening: Quenching & tempering (HB260–300) for impact resistance.
Tooth Surface Hardening:
Carburizing: 1.5–2.0mm case depth, HRC58–62 tooth hardness.
4.Precision Machining of sprocket wheel
Dynamic balancing for high-speed conveyor systems.
Tooth Cutting: CNC hobbing for seamless chain meshing.
Critical Finishing:
Grinding → reduces vibration.
5.Surface Treatment & Packaging
Custom anti-rust protection & secure packaging: We apply corrosion-resistant coatings and use durable plywood cases, tailored to your product’s size, weight, and shipping needs.
Key Features
1.30% Longer Service Life – Advanced surface hardening resists abrasive wear in coal/ore transport.
2. Zero Unplanned Downtime – Reinforced teeth withstand 24/7 heavy loads & frequent starts.
3. Corrosion-Proof in Humid Mines – Specialized coating protects against sulfuric acid & moisture.
4. Seamless Compatibility – Fits all major scraper conveyors, tunneling machines & hoists.
