Jaw Crusher Frames

The frame, a core load-bearing component of jaw crushers, supports key parts like the fixed jaw plate and eccentric shaft, enduring all crushing forces. It features an integral (small/medium crushers) or split (large models) structure with bearing bores, a fixed jaw mounting surface, toggle plate seat mounts, and reinforcing ribs, made of ZG270-500 cast steel or QT500-7. Manufacturing involves sand casting (1480–1520°C pouring) with stress-relief annealing, followed by precision machining (bearing bore tolerance H7, flatness ≤0.1 mm/m). Quality control includes UT/MT for defects, tensile testing (≥500 MPa), and load trials ensuring ≤0.2 mm/m deformation under 1.2× rated load. Critical for structural rigidity, it ensures stable crusher operation with long-term durability.

Jaw Crusher Toggle Plate Seats

The toggle plate seat is a key load-bearing component in jaw crushers, supporting the toggle plate at the frame’s rear wall and swing jaw’s lower part to transmit crushing forces and enable the swing jaw’s oscillation. It comprises a high-strength base body (ZG35CrMo/HT350), a contact surface (spherical concave or flat groove) matching the toggle plate, and fixing structures (bolts, locating pins) with reinforcing ribs for rigidity. Manufacturing involves resin sand casting (1480–1520°C pouring) followed by stress-relief annealing, with precision machining of the contact surface (flatness ≤0.1 mm/100 mm) and assembly holes. Quality control includes MT/UT for defects, hardness testing (≥200 HBW), and load trials to ensure ≤0.1 mm deformation under 1.2× rated load. With a 2–3 year service life, it ensures stable force transmission and equipment safety through strict process control.

Jaw Crusher Bearings

Bearings are core components in jaw crushers, facilitating rotational motion and load-bearing at connections between the eccentric shaft, swing jaw, and frame. Typically spherical roller bearings, they consist of inner/outer rings (GCr15 steel), spherical rollers, cages (brass/stamped steel), and seals (IP54+), designed to withstand radial/axial loads and accommodate angular misalignment. Manufacturing involves forging, spheroidizing annealing, precision grinding, and heat treatment (61–65 HRC for rings). Quality control includes chemical analysis, dimensional checks (tolerances ≤0.005 mm), hardness testing, and MT/UT for defects. With a 8000–12000 hour service life, they ensure efficient crusher operation through high precision and durability, dependent on proper lubrication and maintenance.

Jaw Crusher arm guards

The arm guard (swing arm shield) is a critical safety component in jaw crushers, installed around the swing arm to protect operators and equipment from splashing materials and prevent foreign object entanglement. It consists of a main protective plate (Q235B/Q355 steel), fixing brackets, optional buffer layers, and observation windows, with reinforcing ribs for structural rigidity. Manufacturing involves CNC cutting, forming (bending/pressing), welding, and surface coating (epoxy + polyurethane). Quality control includes material testing, dimensional checks, weld inspection (MT), coating adhesion tests, and installation compatibility verification. With a 1–3 year service life, it ensures safe operation by isolating moving parts and withstanding material impacts.

Jaw Crusher Fixed Jaw Plates

The fixed jaw plate is a stationary wear-resistant component in jaw crushers, working with the swing jaw plate to crush materials via extrusion and splitting. Structurally, it features a toothed working surface, bolt holes for mounting, and reinforced edges, typically made of high manganese steel (ZGMn13) for toughness and wear resistance. Its manufacturing involves sand casting (1400–1450°C pouring) followed by solution annealing to form an austenitic structure, with precision machining to ensure tooth accuracy and mounting fit. Quality control includes chemical composition checks, impact testing, defect detection (UT/MT), and dimensional verification. With a 4–8 month service life, it ensures efficient, uniform crushing through its design and material properties.

Jaw Crusher Tension Rods

The tension rod is a key auxiliary component in jaw crushers, connecting the swing jaw’s lower part to the frame, and functioning to tension the toggle plate and absorb impacts via a spring. It comprises a high-strength rod body, tension spring (60Si2Mn), adjusting nut, and connecting pins, with materials like 40Cr (tensile strength ≥800 MPa) for the rod. Manufacturing involves forging and precision machining of the rod (with heat treatment to 240–280 HBW), spring coiling/heat treatment (38–42 HRC), and strict quality checks (MT/UT for defects, dimensional verification, and tension testing). Quality control ensures stable performance under load, with a 1–2 year service life, critical for crusher safety and operational stability.
