Heavy-Duty Lower frame Guard Plate for Single-Cylinder Cone Crushers
Armored Defense for NMS, Metso & Sandvik Crusher Foundations

Shield your crusher’s structural core from catastrophic damage with our ultra-wear-resistant Lower frame Guard Plate – precision-engineered for seamless compatibility with NMS, Metso, and Sandvik single-cylinder cone crushers. This critical armor absorbs high-impact collisions and abrasive wear, preserving frame integrity in the harshest mining and quarry environments.

Multi-Brand Precision: Bolt-for-bolt fit for NMS, Metso, and Sandvik crusher lower frames – no cutting or welding required.

Impact & Abrasion Defense: 40–50mm AR500 steel construction withstands boulder collisions (+500J impact) and silica-rich material abrasion (granite, iron ore, recycled concrete).

frame Lifespan Multiplier: Protects structural castings from wear-induced cracks, extending frame service life 3–5× in high-tonnage applications.

Vibration Dampening: Reinforced rib design minimizes harmonic resonance transfer to bearings and gears.

Containment Security: Prevents material spillage and dust leakage at the crushing chamber base.

Quick-Replacement Design: Bolt-on installation reduces downtime to <2 hours during liner changes.

Boulder Impact Absorption: Dissipates kinetic energy from oversize feed or tramp metal.

Abrasion Barrier: Shields frame welds and mounting surfaces from high-velocity aggregate streams.

Corrosion Resilience: Optional zinc-aluminum coating for coastal/salt-mine operations.

Thermal Stability: Maintains structural rigidity at operating temperatures up to 200°C (392°F).

Where Every Impact Meets Immovable Resistance.
Trust our Guard Plate to defend your crusher’s foundation – engineered for zero structural compromises.
