Five advantages of PF series impact crusher

PF series impact crusher is widely used in crushing, railway, highway, energy, cement, chemical, construction industries. Why impact crusher has such a broad application? Because it has the following five advantages. Impact crusher can process high-moisture materials effectively, without material blinding in crusher. When impact crusher processes high-moisture materials, its feed chute and impact plate can be equipped with heating device to prevent material sticking. The impact crusher does not need to be equipped with a bottom sieve plate, which effectively prevents material blinding. While the hammer crusher cannot use heating to prevent the material from sticking, and it must be equipped with a bottom screen, which increases the possibility of blockage.

1. Impact crusher is suitable for both soft materials and very hard materials

The hammer of the impact crusher is mechanically clamped on the rotor and has a large moment of inertia when rotating with the rotor. Compared with the hammer crusher (the hammer head is in a dangling state), the rotor of the impact crusher has greater momentum, which is suitable for crushing harder materials, and the energy consumption is lower.

2. The discharge granularity of the impact crusher can adjust conveniently and flexibly, and the adjustment range is wide.

Its discharge granularity can be adjusted in various ways, such as adjusting the rotor speed or adjusting the gap between the impact plate and the grinding chamber. The gap adjustment can be adjusted mechanically or hydraulically. The gap of impact crusher equipped with the hydraulic adjustment system can be conveniently adjusted by operating buttons or the travel control system on the spot. While the hammer crusher can only adjust the output particle size by replacing the bottom screen.

3. The wear parts of impact crusher is less than that of hammer crusher, so it has a high metal utilization.

The wear of the blow bar occurs only on the side facing the material. When the rotor speed is normal, the feeding materials will fall to the surface of the blow bar (hitting surface), and the back and side of the blow bar will not be worn. Even the wear on the side facing the material is minimal. And the bottom grinding rod is easy to replace. The metal utilization rate of the impact crusher plate hammer is up to 45% -48%. However, the hammer crusher's hammer head is in an overhanging state, and the wear occurs on the top, the front, the rear and the side. Compared with the plate hammer, the hammer head wears more seriously, and the metal utilization rate of the hammer head is only about 25%. Also, the rotor body itself may be subject to wear. The sieve plate at the bottom of the hammer crusher is seriously affected by abrasion, and the screen must be completely replaced, and the work of replacing the sieve plate is also more complicated.

4. Easy replacement of impact crusher spare parts correspondingly reduces the maintenance costs

Only 6 plate hammers are installed on the impact crusher rotor. The special tools provided by CFTC can be used to easily replace the plate hammers. It only takes one shift time to replace a set of plate hammers. The replacement of the grinding rod in the bottom grinding cavity only takes tens of minutes, which greatly reduces the time and cost of inspection and maintenance. While the hammer crusher has more than 100 hammer heads. It takes a lot of time and labor to replace a set of hammer heads, and the maintenance and maintenance costs are high.
