Applications of Hydrocone Motor Pulley Bushing

Primary Function: Adjusts the eccentricity of the main shaft in the hydrocone crusher to control crushing speed, regulate output particle size (by adjusting mantle-concave clearance), and increase throughput (more rock per cycle).
Industries: Suitable for stone mining, sand and gravel production, road construction, and mineral processing (secondary crushing of hard rocks).
Compatibility: Designed for Novincsm hydrocones and compatible with Symons, Metso, and Sandvik models; suitable for production lines with hydraulic lubrication systems.

Advantages of Hydrocone Motor Pulley Bushing

Smooth eccentric movement for high efficiency and reduced vibration/noise.
Extended service life (up to 30% longer) through reduced friction and lower maintenance requirements.
Easy adjustment (bushing size can be changed to modify speed/output) and fast installation (pre-lubricated).
Excellent wear and corrosion resistance, reducing waste and ensuring consistent product quality.
Economical: high-quality OEM manufacturing in Iran.

Disadvantages of Hydrocone Motor Pulley Bushing

Sensitive to high oil temperatures (>150°C), which may reduce performance (requires cooling system).
Consumable component: requires periodic replacement every 6–12 months under heavy-duty operation.
Heavy weight (challenging to transport); precise machining required after casting.
In older models, low clearance may cause main shaft damage.

Installation & Maintenance Guidelines

Installation: Clean shaft bore, apply lubricant, use proper tools, and check clearance (0.10–0.15 mm) after installation. Adjust eccentricity with a hydraulic jack.
Maintenance: Regular lubrication (spiral channels), monitor temperature (<150°C), avoid overload. Replace if wear exceeds 5 mm.
Transport: Maximum 500 kg by pickup (1–2 pieces), up to 20 tons by trailer (10+ pieces).
