Cone Crusher head ball

The cone crusher head ball, a critical pivot component atop the moving cone, supports axial crushing loads (tens of thousands of kN), guides eccentric rotation (5–20 mm amplitude), reduces wear, and maintains alignment between the moving cone and concave. Structurally, it features a hemispherical/spherical head (radius 50–300 mm) of GCr15/42CrMo with a 2–5 mm hardened layer (HRC 58–62), a shaft neck, transition fillet (radius 10–30 mm), and lubrication groove. Manufactured via closed-die forging (1100–1200°C) or investment casting, it undergoes quenching/tempering (core HRC 25–35) and induction hardening. Precision machining (CNC grinding) achieves Ra0.1–0.4 μm surface roughness and ≤0.01 mm spherical tolerance. Quality control includes material spectrometry, hardness testing, UT/MPT for defects, and fatigue testing (10⁶ cycles). It ensures reliable performance in mining/aggregate processing with compressive strength ≥2000 MPa and minimal wear (≤0.1 mg loss/10⁴ cycles).

Cone Crusher Counter weight

The cone crusher counter weight, a key dynamic balancing component mounted on the eccentric bushing, offsets centrifugal forces from eccentric rotation, reducing vibration, enhancing stability (500–1500 rpm), optimizing energy use, and balancing frame loads. Structurally, it comprises a high-density (7.0–7.8 g/cm³) body (HT350/QT600-3), 2–6 annular segments, bolt holes (class 8.8+), locating pins, balancing tabs, and reinforcement ribs, with a corrosion-resistant coating. Manufactured via sand casting (1350–1380°C pouring), it undergoes annealing (550–600°C) and precision machining (CNC turning/grinding) for dimensional accuracy. Quality control includes material testing (density ≥7.0 g/cm³), NDT (UT/MPT), dynamic balancing (≤5 g·mm/kg residual imbalance), and load testing (150% rated force). This ensures reliable operation in mining/aggregate processing by minimizing stress and extending component life.

Cone Crusher adapter ring

The cone crusher adapter ring, a key component between the main shaft and moving cone, transmits torque and axial loads, compensates for minor misalignment, protects high-cost parts, and eases assembly. It operates under high torque and cyclic loads, demanding strength and precision. Structurally, it features a tapered alloy steel (40CrNiMoA or 45#) body with a precision inner taper (1:10 to 1:20), outer threads/flange, keyway, lubrication grooves, and a positioning shoulder. Manufacturing involves forging (heating to 1150–1200°C, upsetting/piercing) or casting, followed by quenching/tempering (HRC 28–35). Machining includes precision grinding of the taper (Ra0.8 μm) and threading. Quality control covers material testing (composition, tensile/impact strength), dimensional checks (CMM, taper gauge), NDT (UT, MPT), torque/fatigue testing, and assembly validation. These ensure reliable performance in torque/load transmission for efficient crusher operation.

Cone Crusher dust shell

The cone crusher dust shell, a protective component at the crusher's upper part, prevents dust, debris, and moisture from entering internal parts (e.g., adjustment gear, thrust bearing), enhances safety by blocking access to moving components, and reduces noise. It operates in harsh, dusty environments, requiring durability and a tight seal. Structurally, it includes a thin-walled shell body (mild steel, stainless steel, or cast iron), upper/lower flanges with seals, reinforcement ribs, inspection doors, optional ventilation holes, and lifting lugs. Manufacturing processes vary by material: mild/stainless steel shells undergo cutting, rolling, welding, and finishing; cast iron shells use sand casting and heat treatment. Machining focuses on flange flatness and seal surfaces, with surface treatments like painting or passivation. Quality control involves material testing, dimensional checks, structural integrity tests (weld inspection, pressure testing), functional tests (seal performance, impact resistance), and assembly validation. These ensure the dust shell reliably protects internal components, supporting the crusher's efficient operation

Cone Crusher clamping ring

The cone crusher clamping ring, a key fastening component between the adjustment ring and lower frame, secures the concave and stabilizes the bowl assembly. It fixes the concave, locks adjustments, distributes loads, and enhances sealing, enduring high clamping forces and cyclic loads. Structurally, it includes a high-strength cast/forged steel ring body, precision clamping surface, bolt holes, lifting lugs, locating features, and reinforcement ribs, with optional wear-resistant coatings. Manufacturing involves sand casting (ZG35CrMo) or forging (35CrMo), followed by heat treatment, machining (CNC turning/grinding for precision), and surface treatment. Quality control covers material testing (composition, mechanics), dimensional checks (CMM, laser tracking), structural integrity tests (UT, MPT), mechanical performance trials (clamping force, fatigue), and assembly validation. These ensure it reliably secures components for consistent crusher operation in mining and aggregate processing.

Cone Crusher Lower Frame

The cone crusher lower frame, a foundational structural component, supports the entire assembly, distributes loads to the foundation, houses critical parts (thrust bearing, main shaft socket), and protects against contamination. It demands high rigidity and strength. Structurally, it includes a cast steel/ductile iron body (500kg–5 tons) with reinforcing ribs, thrust bearing seat, main shaft socket mount, lubrication/cooling channels, foundation flange, access ports, and sealing surfaces. Manufacturing involves sand casting (material selection, pattern making, molding, melting/pouring) with heat treatment, followed by machining (rough and precision) and surface treatment. Quality control covers material testing, dimensional checks (CMM, laser scanning), structural integrity testing (UT, MPT), mechanical performance tests, and assembly validation, ensuring it meets strength and precision requirements for reliable heavy-duty operation.
