How Much Do You Know About Impact Crusher?
Date：2021-01-27
The impact crusher is named according to the working principle, that is, the principle of impact crushing is used to crush materials. It is a finer crusher equipment compared with jaw crusher. In the stone production line, it is mainly used for fine crushing operation, and combined with jaw crusher for crushing.
Impact crusher has the following five advantages in the process of crushing.
Ⅰ. The impact crusher is more effective in handling wet materials, effectively preventing material blockage.
Impact crusher has the following five advantages in the process of crushing.
Ⅰ. The impact crusher is more effective in handling wet materials, effectively preventing material blockage.
When the moisture content of the material is too high, the feeding chute and impact plate of the impact crusher can be equipped with heating device to prevent the material from sticking. Impact crusher does not need to be equipped with bottom sieve plate, which can effectively prevent clogging.
Ⅱ. The impact crusher is applicable to a wider range of material hardness.
Ⅱ. The impact crusher is applicable to a wider range of material hardness.
The plate hammer of impact crusher is fixed on the rotor by mechanical clamping structure. When it rotates with the rotor, it has a large moment of inertia. The rotor of impact crusher has larger momentum, so it is suitable for crushing harder materials and has lower energy consumption.
Ⅲ. It is convenient and flexible to adjust the discharge particle size, and has a wide range of adjustment.
The discharge particle size can be adjusted in many ways, such as adjusting the rotor speed, adjusting the gap between the impact plate and crushing chamber, etc. The clearance can be adjusted by mechanical or hydraulic control. The hydraulic control system can be used to adjust the clearance easily by local operation button or distance control system.
Ⅳ. Low wear of vulnerable parts and high metal utilization rate
The wear of the hammer is only on the side facing the material. When the rotor speed is normal, the feed will fall to the surface of the hammer, and the back and side of the hammer will not be worn. There is little wear even on the side facing the material. And the bottom grinding rod is easy to replace. The metal utilization rate of impact crusher hammer can be as high as 45% - 48%.
Ⅴ. The replacement of spare parts of impact crusher is simple and the maintenance cost is reduced accordingly
Only 6 plate hammers are installed on the rotor of impact crusher. The designed special tools can be used to replace the plate hammers conveniently. It only takes one shift to replace a set of plate hammers.
Working principle of impact crusher
Impact crusher uses impact energy to crush materials. When the machine is working, the motor drives the rotor rotate at a high speed. When the material enters the affecting area of the blow bar, it will be stroke by the blow bar and be thrown to the impact devices around the rotor. Then it bounces back from the impact liner to the area where the blow bar effectsuntil they have been crushed to the required size. The clearance between the impact rack and the rotor can be adjusted to change the size and shape of the endn product.
Crushing process of impact crusher
With a novel design principle and a new concept of crushing technology, the impact crusher can meet the requirements of different material specifications and the new process of "more crushing and less grinding". By adopting the crushing method "crushing between material and liner", the crushing ratio is large and the power consumption is low. Through large-scale engineering projects, it is proved that this machine has a good application prospect in the field of mineral processing.
VANGUARD is a professional crusher manufacturer producing a variety of impact crushers which can be used for material processing in sand and gravel plant, and can reduce the operation cost of equipment and improve its economic benefits.
