Jaw Crusher swing Jaw Plates

The swing jaw plate is a key wear-resistant component in jaw crushers, working with the fixed jaw plate to crush materials via reciprocal movement. Structurally, it includes a toothed working surface, mounting holes, and reinforcing edges, typically made of high manganese steel (ZGMn13) for toughness and wear resistance. Its manufacturing involves sand casting (1400–1450°C pouring) followed by water quenching to form an austenitic structure, with machining to ensure tooth precision and mounting accuracy. Quality control covers chemical composition, impact toughness, casting defects, and dimensional accuracy. With a 3–6 month service life, it ensures efficient crushing through its design and material properties.
