In terms of working principle, hydraulic cone crusher drives the eccentric sleeve to rotate through hydraulic motor, drives the moving cone to do pendulum motion, so that the material is subjected to multi-directional extrusion and grinding in the crushing chamber. Its unique lamination crushing principle ensures that the cubic proportion of the discharged particles is as high as more than 85%, which significantly improves the construction value of the finished aggregate. The hydraulic system not only provides power support, but also realizes real-time stepless adjustment of the discharge port. The adjustment range is usually 3-60mm, which fully meets the particle size requirements of different working conditions.

In terms of equipment structure, hydraulic cone crusher is mainly composed of key components such as frame, transmission device, eccentric sleeve assembly, hydraulic system, intelligent control system, etc. The hydraulic system includes hydraulic adjustment mechanism, hydraulic locking mechanism and hydraulic overload protection device. The coordinated work of these three ensures the stability and safety of equipment operation. When encountering unbreakable objects, the hydraulic system can respond quickly and complete unloading protection within milliseconds, minimizing the risk of equipment damage.

In terms of performance characteristics, hydraulic cone crusher has four significant advantages: first, high crushing efficiency, with a 15-30% increase in production capacity compared with spring type at the same power; second, high degree of automation, which can realize remote monitoring and intelligent adjustment; third, convenient maintenance, hydraulic cavity clearing function shortens maintenance time by more than 50%; fourth, low energy consumption, and the power consumption per ton of crushing is 20-25% lower than that of traditional equipment. These advantages make it widely used in large-scale sand and gravel aggregate production lines and mineral processing plants.

In terms of application areas, the equipment is particularly suitable for processing high-hardness materials such as granite, basalt, iron ore, etc., with a compressive strength of more than 350MPa. In the sand and gravel industry, it is mainly used for secondary or tertiary crushing; in the field of mineral processing, it is often used as pre-grinding fine crushing equipment. With the development of intelligence, the new generation of hydraulic cone crushers have begun to be equipped with Internet of Things systems, which can realize fault warning and remote diagnosis, representing the future development direction of crushing equipment.

In terms of maintenance, hydraulic cone crushers need to regularly check the quality of hydraulic oil and oil circuit sealing, and replace wear parts in time. Under normal maintenance conditions, the service life of the equipment can reach 8-10 years, and the replacement cycle of major wearing parts (such as linings) is between 400-600 working hours. A reasonable maintenance plan can ensure that the equipment always maintains the best working condition.
