Impact Crusher Product Description
Brief Introduction of Impact Crusher
Impact crusher is the use of impact energy can break the material of the equipment. On the use of mechanical energy in the form of the use of the impact of "free" broken crusher, than the pressure of the crushing principle of crushing crusher superior. When the material in the hit plate and counterattack board between the way back and forth, in addition to the impact plate and counterattack plate impact, there are mutual impact between the role of the material.
The working principle of the impact crusher
The counter-crusher uses a plate hammer on a high-speed rotating rotor to create a high-speed impact on the material entering the crushing chamber and break the broken material at a high speed to the other end of the crushing chamber Was broken, and then rebound from the counterattack plate to the hammer, continue to repeat the process. On the way back and forth, there is a collision between the material. As the material by the plate hammer blow, and the impact of the impact plate and the collision between the material, the material continue to produce cracks, loose and crushed. When the particle size is less than the gap between the counterweight and the plate hammer, it is discharged.
Impact crusher classification
Impact crusher according to its structural characteristics can be divided into single rotor impact crusher and double rotor impact crusher.
According to the rotor steering, single rotor counter crusher is divided into two types: reversible rotation and irreversible rotation. Double rotor impact crusher can be divided into the same direction of rotation, reverse rotation and reverse rotation of three types.
According to the internal structure, single rotor counterattack crusher is divided into two parts with uniform rectification board and not even with the rectification board. Double rotor impact crusher can be divided into two types: the rotor is at the same level and the rotor is not in the same level.
Impact crusher performance characteristics
1, crushing ratio (Note: crusher into the material size and the upper limit of the ratio of material size) is very large, the general crusher crushing ratio of not more than 10, and counterattack crusher crushing ratio is generally 30-40, the largest Up to 150.
2, high crushing efficiency, low power consumption. Because the general material of the impact strength is much smaller than the compressive strength, and because the material by the impact of the plate after the high-speed and multiple impact, the material along the powder cleavage interface and fragile tissue first cracked, so this type Crusher crushing efficiency is high, and the power consumption is low.
3, the product size uniformity, less crushing phenomenon. This crusher is the use of kinetic energy to break the material, and each piece of material has a kinetic energy and the quality of the material is proportional to the block. Therefore, in the process of crushing, large pieces of material subject to a greater degree of broken, and smaller cities of the material, under certain conditions are not broken. So broken product size uniformity, too little crushing phenomenon.
4, can be selectively broken. In the process of impact crushing, the material is first broken along the cleavage plane to facilitate the separation of the material from the monomer.
5, adaptability. This crusher can be broken brittle, fibrous and hard in the following materials, especially for brittle materials broken.
6, the device small size, light weight, simple structure, easy manufacturing, easy maintenance.
Based on the impact crusher with these obvious advantages, the current countries are widely used, vigorously develop. But the impact crusher also has shortcomings, broken hard material, the plate hammer (hit plate) and counterattack plate wear faster. In addition, the impact crusher is high-speed rotation and by the impact of the broken machine, parts processing accuracy requirements, and to carry out static balance in order to extend the service life.

The role of flywheel in jaw crusher
Flywheel is a jaw crusher in a very conspicuous big guy, many people wonder how the flywheel in the end is doing? Jaw crusher with two flywheels, one of the flywheel for connecting the V-belt and eccentric shaft, the other from the shape seems to see what role it does not increase the weight of the equipment, can not be removed? joyal machinery in the following will be announced for everyone one by one.
Flywheel is a part of the mine equipment is inseparable from the parts, but also play a key role in the various crusher equipment, the flywheel is playing an irreplaceable role, so the flywheel can not be removed, while the equipment running The process of flywheel also plays a very important role.
From the appearance of jaw crusher equipment, we can easily see that the jaw crusher on both sides of the equipment has two large iron wheels, the two wheels is what we call the flywheel. Two flywheels at both ends of the eccentric shaft, one of the flywheel for connecting the V-belt and eccentric shaft, transmission kinetic energy; the other is a lot of people no use in the eyes of the flywheel, in fact, the flywheel in the jaw crusher running Crucial role. The main reason also from the jaw crusher working principle, jaw crusher is an indirect work of the equipment, which led to the resistance on the eccentric shaft will change, the motor load is uneven, the formation of mechanical rate fluctuations. And this flywheel is to make the motor load evenly, reduce the motor rated power and reduce the mechanical rate fluctuations and installation.
The flywheel stores the energy of the jaw crusher when it is empty and is released when the jaw is squeezed. That is, when the jaw plate moves away from the fixed jaw, the flywheel accumulates energy, and when the flywheel is closed, the flywheel transfers the accumulated energy for the material of the crusher, so that the load of the motor can be made uniform and the rated power of the motor can be reduced. It is because of the flywheel, jaw crusher energy consumption was able to be uniform.
Here, joyal machinery still have to say that not all of the jaw crusher is only a flywheel connected to the V-belt, there are two are connected to the Vane flywheel, if there are two large motor jaw crusher Are a dual purpose, the two flywheels are regarded as a pulley connected to the V-belt. This simplifies the equipment of the organization, but also make the best use.
