Crushing equipment plays a crucial role in mining development, with gyratory crushers mainly undertaking the initial crushing of raw ore. Its working environment is quite harsh, not only frequent need to start with load, but also need to deal with different sizes and properties of the ore, which leads to the extreme instability of the load. Therefore, in order to ensure safe and continuous operation, the machine itself must have excellent self-protection mechanisms. Hydraulic control technology is now being increasingly used in crushers due to its fast response time and ease of overload protection.
Hydraulic crusher includes hydraulic crusher, working device, hydraulic device, electrical device, maneuvering device, and also includes frame, swinging device, turning cylinder, etc. Hydraulic crusher is simple in structure, easy to operate, easy to maintain, low energy consumption, low noise, large crushing ratio and high output. It is suitable for various hardness materials, such as iron ore, copper ore, gold ore, silver ore, manganese ore, lead-zinc ore, molybdenum ore, tungsten ore, limestone, granite, basalt, diorite and so on. The hydraulic control technology greatly improves the rated power and passing capacity of the equipment, realizing selective crushing of materials and uniform crushing size.
Hydraulic crusher has high efficiency, but still need to follow certain rules in the process of using, the following points can help you better use hydraulic crusher:
(1) Before operating the hydraulic crusher, safety check is an indispensable and important part. You should carefully check whether the bolts and connectors are loose, and whether there is any leakage in the hydraulic pipeline. Through these careful checks, we can ensure the integrity and safety of the whole system, laying a solid foundation for the next work.
(2) When using the hydraulic crusher, its working principle and performance characteristics must be followed. It is determined not to try to forcibly peck holes in hard rocks, which may cause serious damage to the crusher's cutter head, cutter seat, and hydraulic system, and may even cause safety accidents. When encountering hard-to-break rocks, we should adopt appropriate methods, such as adjusting the impact frequency and strength of the crusher, or using other suitable tools for crushing.
(3) If you find violent vibration of the hydraulic hose during operation, you should stop the operation of the crusher immediately and check the pressure of the accumulator carefully. This is because violent vibration of the hydraulic hose may be caused by insufficient or unstable accumulator pressure, which will lead to instability of the hydraulic system and decrease of working efficiency. When checking the accumulator pressure, we should use professional tools and equipment and follow the manufacturer's recommendations.
(4) No part of the crusher should be immersed in water except the drill bit part. This is because water will cause corrosion and damage to the metal materials of the crusher, as well as affect the performance and life of the hydraulic crusher. If it is necessary to work in a water-containing environment, appropriate protective measures should be taken, such as using a waterproof cover or applying waterproof coating.
(5) The optimum hydraulic oil temperature of the hydraulic crusher during operation should be between 50 and 60 degrees, with a maximum of 80 degrees. If the oil temperature is too high, it will lead to the reduction of the viscosity of the hydraulic oil, the decrease of the lubrication performance and the acceleration of the aging of the seals, thus affecting the performance and life of the crusher. In order to keep the oil temperature within the proper range, the temperature and cleanliness of the hydraulic oil should be checked after a long period of work and replaced or supplemented as needed.
With the accelerated integration of mining resources, the continuous expansion of enterprise scale and the significant improvement of production efficiency, the crusher is gradually evolving in the direction of large-scale, which puts forward higher requirements for the automation and intelligence level of the equipment. Hydraulic control technology, by virtue of its control mode of high flexibility and ease of operation, in the crusher is increasingly expanding the scope of application.
