High-Integrity Wedge Ring for Single-Cylinder Cone Crushers

Engineered by NMS – The Ultimate Locking Assurance

Wedge Ring Assembly
Compatible with Metso HP/GP, Sandvik CH/CS Series & E Crushers

Revolutionary Locking Technology

► Hydraulic Preload System

Self-energizing Taper: 7° precision angle generates 350+ MPa clamping force

Force Distribution: FEA-optimized ribs eliminate stress concentration (tested to 600 kN)

► Fail-Safe Mechanism

Dual-Lock Design: Primary wedge + secondary retention collar

Anti-Vibration: Serrated contact surfaces prevent rotation under 12g vibration

► Zero-Maintenance Operation

Corrosion Defense: HVOF-sprayed WC-Co coating (1,200+ HV)

Gall Prevention: Molybdenum disulfide embedded surface treatment

Critical Value Drivers

▣ Eliminates Unscheduled Downtime

**** prevention of liner displacement incidents (validated in 24/7 iron ore operations)

▣ Precision Installation

Color-coded match marks ensure correct angular orientation

Torque sequence indicator eliminates over-tightening risks

▣ Lifetime Cost Reduction

No consumable parts required

Compatible with all standard liner profiles

Engineering Excellence

Material Science: Vacuum-degassed 42CrMo4 steel

Heat Treatment: Quench & temper to 40-44 HRC core hardness

Geometric Tolerance: Profile deviation Thermal Stability: -40°C to 300°C without preload loss

Failure Mode Prevention

▪ Liner slippage ▪ Eccentric bushing damage ▪ Hydraulic cylinder overload ▪ Crusher head wobble

Application Environments

Ultra-fine crushing circuits (>400 rpm eccentric speed)

Mobile crushing plants with frequent relocation

High-moisture ore processing (copper/zinc mines)

NMS Commitment to Crusher Safety
Synergizes with NMS mantles/concaves for optimized crushing chamber security.
