The impact crusher has different working mechanisms and structural design features. So how is the specific difference? Let's compare the impact crusher with the hammer crusher, and let's take a look together.
Wider flow adjustment range
This machine can adjust the discharging particle size conveniently and flexibly, and the adjustment range is relatively wide.
The discharge particle size of the impact crusher can be adjusted in many ways, such as adjusting the rotor speed and adjusting the gap between the impact plate and the grinding chamber. The gap adjustment can be mechanically or hydraulically adjusted, and the gap can be easily adjusted by operating the button or the transportation control system on the spot using the hydraulic adjustment system. However, the adjustment of the discharge particle size of the hammer crusher can only be achieved by changing the bottom sieve plate.
Less wear on wearing parts
The wearing parts of impact crusher are smaller than hammer crusher, and metal utilization rate is high.
The wear of the hammer of the impact crusher only appears on the side facing the material. When the rotor speed is normal, the feed will fall on the hammer surface (impact surface), and the back and sides of the hammer will not wear. Even the side facing the material is basically free of wear. And the bottom grinding rod is easy to replace. However, the hammer head of the hammer crusher is in a cantilevered state, and the wear mainly occurs on the top, front, back and side. Compared with the plate hammer, the hammer head wears more serious, and the metal utilization rate of the hammer head is only about 25%. The rotor body itself may also wear. The bottom sieve plate of the hammer crusher is seriously worn, and the sieve used needs to be replaced, and the replacement of the sieve plate is also more complicated.
Can handle materials with high moisture content and reduce clogging
The impact crusher can better handle materials with large water content and reduce the blockage of the crusher.
When the water content of the material is too high, the feed tank and the impact plate of the impact crusher can be equipped with a heating device to prevent the material from sticking. The impact crusher does not need to be equipped with a bottom screen, which can better reduce blockage. The hammer crusher cannot be heated to reduce material adhesion and needs to be equipped with a bottom screen, which increases the possibility of blockage.
Material adaptability is wide
Impact crusher is not only suitable for soft materials, but also for materials with higher hardness.
The plate hammer of the impact crusher is fixed on the rotor with a mechanical clamping structure, and the moment of inertia is large when the rotor rotates. Compared with hammer crusher (hammer head suspension), impact crusher has larger rotor momentum, suitable for crushing harder materials, and lower energy consumption.
