Jaw Crusher Front wall

The front wall is a key component of jaw crushers' crushing chambers, supporting the fixed jaw plate and withstanding initial material impact. It consists of a main plate (ZG30Mn/Q355B), fixed jaw mounting structures (T-slots/bolts), connecting flanges, and reinforcement ribs, with optional wear liners and leakage-prevention lips. Manufacturing involves cast steel casting (1460–1500°C pouring) with stress-relief annealing, followed by precision machining (flatness ≤0.1 mm/m for mounting surfaces) and surface coating. Quality control includes MT/UT for defects, hardness testing (≥200 HBW), and load trials (1.2× rated force) to ensure ≤0.2 mm deformation. With a 3–5 year service life, it ensures stable crushing via structural rigidity and precise assembly, critical for feeding efficiency and material containment.
