Applications of Hydrocone Shaft Nut Ring

Primary Function:
Secures the motor while absorbing mechanical vibrations and shocks in the Hydrocone crusher to maintain balance and reduce noise and vibration.

Industries:
Stone mining, sand and gravel production, road construction, and mineral industries (secondary crushing of hard rocks).

Compatibility:
Novincsm Hydrocones, models 36–2/3/4/5/6.5/8; suitable for high-load production lines.

Advantages of Hydrocone Shaft Nut Ring

  • Vibration Reduction: Reduces vibration and oscillation by up to 50%, extending motor and equipment life by up to 30%.

  • Dynamic Balance: Maintains balance and dissipates torque, improving overall efficiency and reducing energy consumption.

  • Easy Installation: Simple mounting with bolts and pins; highly durable under harsh conditions (wear and pressure resistant).

  • Cost-Effective: Locally manufactured in Iran with OEM-quality; available in rubber or steel versions.

Disadvantages of Hydrocone Shaft Nut Ring

  • Consumable Part: Requires replacement every 6–18 months under heavy-duty operation; rubber components sensitive to oil and acids.

  • Medium Weight: Challenging transport; requires precise leveling to avoid imbalance.

  • Older Models: Susceptible to damage under severe vibration; may require a cooling system.

Installation and Maintenance Guidelines

Installation:

  • Clean contact surfaces thoroughly.

  • Attach one metal plate to the moving part (motor) and the other to the frame using M12–M16 bolts.

  • Check leveling (clearance 0.05 mm) and use hydraulic tools for fixing.

Maintenance:

  • Periodic inspection every 500 operating hours for cracks and wear.

  • Avoid overload conditions.

  • Replace rubber components if hardness exceeds 10%.

  • Lubricate metal connections regularly.

Transport:

  • Up to 100 kg via pickup truck (10–15 units).

  • Up to 15 tons via trailer (200+ units).
