The impact crusher can process materials with a side length of 100-500 mm or less, with a compressive strength of up to 350 megapascals, and has the advantages of large crushing ratio and cubic particles of materials after crushing. It is widely used in building materials, ore crushing, railways, highways, energy, transportation, energy, cement, mining, chemical and other industries. The size of the discharge can be adjusted, and the crushing specifications are diversified.
The impact crusher is named according to the working principle, that is, the principle of impact crushing is used to crush the material, which is a finer crusher equipment than the jaw crusher, which is mainly used for fine crushing operations in the stone production line and cooperated with the jaw crusher. The impact crusher has the following five advantages in the crushing process.
1. The impact crusher is more effective in dealing with materials with large moisture and effectively prevents material blockage.
When the water content of the material is too large, the feed chute and impact plate of the impact crusher can be equipped with a heating device to prevent the bonding of the material. The impact crusher does not need to be equipped with a bottom screen, which can effectively prevent clogging.
2. The hardness of the materials suitable for the impact crusher is more extensive.
The plate hammer of the impact crusher is firmly fixed on the rotor with a mechanical clamping structure, and has a large moment of inertia when rotating with the rotor. Compared to hammer crushers, where the hammer head is overhanged, the rotor of the impact crusher has more momentum, which is suitable for crushing harder materials and consumes less energy.
3. It can easily and flexibly adjust the discharge particle size, and the adjustment range is wide
The impact crusher can adjust the discharge particle size in a variety of ways, such as adjusting the rotor speed, adjusting the gap between the impact plate and the grinding chamber, etc. The gap adjustment can be adjusted mechanically or hydraulically, and the hydraulic adjustment system can be easily completed through the local operation button or the transportation control system.
4. The wear of wearing parts is small and the metal utilization rate is high
The wear of the hammer of the impact breaker is only on the side facing the material. When the rotor speed is normal, the feed material falls to the surface of the blow bar (striking surface) and the back and sides of the blow bar are not worn. Even on the side facing the material, there is very little wear. And the bottom grinding rod is also easy to replace. The metal utilization rate of impact crusher blow hammer can be as high as 45%-48%.
5. The spare parts of the impact crusher are easy to replace and the maintenance cost is reduced accordingly
Only 6 blow bars are installed on the rotor of the impact crusher, and the blow bars can be easily replaced with special tools designed to replace a set of blow bars in just one shift.
