Spring cone crusher is mainly composed of frame, transmission, empty eccentric shaft, bowl bearing, crushing cone, adjusting device, adjusting sleeve, spring and hydraulic station for adjusting ore discharge mouth. It is a crusher with high power, large crushing ratio and high productivity. It is suitable for fine crushing and ultra-fine crushing of hard rocks, ores, slags, refractories, etc.

When the spring cone crusher is working, the motor drives the eccentric sleeve to rotate through the transmission device. The moving cone rotates and swings under the force of the eccentric shaft sleeve. The section where the moving cone is close to the static cone becomes the crushing chamber. After the crushed materials enter from the feed inlet, they are squeezed and impacted by the moving cone and the static cone for many times to form materials with the required particle size. When the moving cone leaves this section, the formed material falls under its own gravity and is discharged from the cone bottom. Now let's take a look at what role the rubber spring plays in the spring cone crusher?

Rubber spring is a kind of high elastic body made of ordinary rubber. The elastic modulus of rubber spring is small, and there is greater elastic deformation after loading, so as to absorb impact and vibration. It can bear multi-directional loads at the same time, but its high temperature resistance and oil resistance are worse than those of steel springs. Oil resistant rubber can be used if there are special requirements.

The rubber spring has good damping effect, small resonance field, long service life, low cost, and good cold resistance, excellent air tightness, water resistance, and electrical insulation. It is a good choice for vibration reduction. The basic principle of vibration isolation The more feasible way to avoid vibration is to take measures to isolate the research object (such as equipment or foundation) from the vibration source, so that the vibration transmitted from the vibration source to the research object can be weakened or even eliminated. This method of isolating the vibration source from the research object is called vibration isolation.

Vibration isolation (referred to as vibration isolation) is a widely used vibration reduction technology, which uses additional subsystems to isolate the vibration source from the research object to reduce the impact of the vibration source. In engineering, vibration isolation is divided into active vibration isolation and passive vibration isolation for different vibration sources. When the research object itself is a vibration source, it is isolated from the supporting platform to reduce the impact on the platform, which is called active vibration isolation; If the vibration source comes from the platform, the research object is isolated from the platform to reduce the impact on the equipment, which is called passive isolation.

Rubber compound spring is widely used in vibration isolation system of crusher. During the operation of cone crusher, it will be affected by various forces, and vibration is a common force. The load acting on the body of the inertia cone crusher is the inertia force and inertia moment generated by the moving cone and the vibration exciter. This dynamic load is periodic and will cause the vibration of the crusher, which will lead to noise and unstable operation of the equipment. In serious cases, it will lead to damage to machine parts and shorten the service life of the machine. In order to ensure the normal operation of the crusher, the simple and easy way to reduce the impact of vibration on the machine is to isolate the vibration source for calculation and analysis.
