Detailed Introduction

The cone crusher has high crushing efficiency, low maintenance cost, can be used for medium and fine crushing of high hardness materials, can adapt to different production process requirements, and has become the mainstream crushing equipment in the mining crushing industry. Cone breaking can have such effects, or the main reason for being so favored is that its iron crossing protection device-a hydraulic cylinder instead of a spring plays a buffering and adjusting role in the cone breaking. So, if the hydraulic cylinder has a problem, how to solve it?

Protection measures of hydraulic cylinder of cone crusher

The hydraulic pressure in the hydraulic cylinder can control the swing of the moving cone according to the force of the moving cone, so as to control the size of the output particle size of the crushed finished product. If the crushing cavity of the machine enters the unbreakable high-hardness ore The material, through the role of the hydraulic cylinder, can expand the discharge port of the machine to discharge unbreakable materials, so as to protect the crusher, and this is the role of the hydraulic cylinder in the cone crusher. When the hydraulic cone crusher enters an unbreakable object (such as an iron block), the crushing force increases. At this time, the pressure of the thrust plate of the cone crusher on the working hydraulic cylinder is greater than the thrust provided by the hydraulic cylinder. The oil pressure in the high-pressure oil chamber of the hydraulic cylinder rises momentarily, the throttle valve makes the action valve act, the system drains oil, limits the thrust of the thrust plate (that is, greater breaking force) and protects the river pebble cone.

Therefore, the role of the cone crusher hydraulic cylinder is to protect the equipment from being damaged when the cone crusher enters the unbreakable object. Therefore, the pressure of the hydraulic cylinder should be compatible with the crushing force of the cone crusher. The crusher passes iron during normal work. Protection device-the hydraulic cylinder will not move. Only when the iron block falls into the crushing cavity to overload the crusher, the support sleeve is lifted and the hydraulic cylinder is compressed.

The locking hydraulic cylinder on the cone crusher is not only a device that causes normal crushing force, but also a safety device that protects the crusher from damage when it passes through the iron. Therefore, the tightness of the hydraulic cylinders (height after compression) should be adjusted within the range specified in the instructions, and the tightness of each group of hydraulic cylinders should be adjusted to a consistent degree.

If the hydraulic cylinder already has the required tightness, but the support sleeve often bounces, the reason must be found out, and the method of compressing the hydraulic cylinder again cannot be used to solve it. Because the hydraulic cylinder is excessively compressed, the safe compression process of the hydraulic cylinder is reduced, and the load of the machine is increased. When entering non-broken objects, it will cause damage to important parts such as the hydraulic cylinder screw spindle.

If the hydraulic cylinder has normal tightness, but the support sleeve still bounces frequently, there are several possible reasons for this. For example, non-broken material enters the machine; uneven or excessive amount of ore is fed; too much ore is fed to the ore; ore discharge opening is small; ore is wet and the ore discharge is blocked, etc. After the process, the symptoms are eliminated. The beating phenomenon caused by hard ore and insufficient hydraulic cylinder strength is that the performance of the machine is not suitable for the ore production and processing conditions and should be adjusted in time.
