Cone crushers are widely used in industries such as aggregates, cement, and mineral processing. As the crushing equipment industry continues to grow rapidly, cone crushers have undergone significant upgrades, resulting in a broader range of models and increasing market relevance. The hydraulic system is a key component of the cone crusher, playing a crucial role in determining its crushing capacity and operational efficiency. Therefore, it is essential for processing plants to place great importance on the proper maintenance of the hydraulic system.

Proper Maintenance Methods for Cone Crusher Hydraulic Systems
With over 30 years of experience in cone crusher manufacturing, SUHMAN has summarized the following key points for hydraulic system maintenance, based on current market conditions and real-world operating scenarios:
- Regular Internal Cleaning of the Cone Crusher
Many plants operate outdoors, where airborne dust is inevitable during crusher operation. It is essential to strengthen dust removal efforts and prevent dust, moisture, and other contaminants from entering the machine’s interior. - Regular Replacement of Hydraulic Oil
Over time, hydraulic oil can become contaminated, which degrades its performance. To maintain optimal functionality, the hydraulic oil must be replaced at regular intervals. Always use a dedicated filter when adding oil, and ensure the oil level stays within the recommended range. Ideally, oil replacement should be carried out shortly after the machine has stopped, as this allows for more effective drainage of oil and sediment. - Keep All Components Clean
Before putting the cone crusher into operation, all components, pipelines, and systems must be thoroughly cleaned. Any worn parts should be repaired or replaced to prevent potential failures. - Use a Sealed Oil Tank
To prevent foreign matter from entering the tank, a sealed oil tank is recommended. In addition, the oil inlet should be equipped with an air filter of appropriate precision.
In conclusion, the performance of the hydraulic system directly affects the overall operation and lifespan of the cone crusher. Therefore, it is critical for plants to implement proper maintenance strategies to ensure reliable operation.
