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.
