The HP300 Cone Crusher Countershaft serves as a vital power transmission core in mining-grade cone crushers, engineered to bridge the operational gap between the main drive system and crushing mechanism. Its robust design targets the rigorous demands of mining environments, where continuous exposure to high torque (up to 2,800 N·m) and abrasive mineral particles is standard. As a key component of Metso’s HP300 cone crusher, it facilitates seamless energy transfer from the motor to the crushing chamber, directly influencing the crusher’s throughput capacity—typically ranging from 200 to 500 tons per hour in medium-scale mining operations. The assembly includes precision-machined bearings and a reinforced shaft body, ensuring alignment with industry standards for heavy-duty mineral processing equipment.
Material Engineering: Forged from high-strength alloy steel (ASTM A36 grade) with a carbon content of 0.25–0.29%, the countershaft undergoes a dual heat treatment process (normalizing at 890°C followed by tempering at 650°C) to achieve a tensile strength of 620–700 MPa, balancing hardness and ductility .
Dimensional Accuracy: CNC machining ensures shaft concentricity within ±0.05 mm and surface roughness of Ra 1.6 μm, minimizing rotational friction and extending bearing life by 15–20% compared to non-precision alternatives.
OEM Compatibility: Manufactured to match Metso’s original part specifications (Part No. 300-1234), it eliminates the need for modification during installation, reducing maintenance labor by approximately 3 hours per replacement.
Dynamic Performance: Equipped with a built-in vibration dampening sleeve, it operates within a resonance frequency range of 120–150 Hz, preventing harmonic oscillations in multi-crusher setups.

Hard Ore Processing: Critical for crushing granite, diabase, and magnetite in iron ore mines, where compressive strength exceeds 200 MPa.
Aggregate Quarries: Integral to producing 40–80 mm aggregate fractions for high-strength concrete in infrastructure projects.
Mining Rehabilitation: Used in mobile crushing units for on-site processing of overburden material during mine site restoration.
Q: What are the signs of countershaft wear?
A: Abnormal noise during operation, increased vibration (exceeding 0.5 mm/s), or irregular wear patterns on the associated pulley indicate potential countershaft degradation.
Q: Is specialized equipment required for installation?
A: A hydraulic press (capacity ≥ 50 tons) and dial indicator (precision ±0.01 mm) are recommended to ensure proper alignment.
Q: How does operating temperature affect performance?
A: Optimal performance occurs between -10°C and 60°C; prolonged exposure to temperatures above 70°C may accelerate lubricant degradation.
