The advantages of the impact crusher compared with hammer crusher

Both the impact crusher and the hammer crusher crush the material through high-speed impact and the shapes of the two devices are very similar. What are the advantages of impact crusher compared to hammer crusher?
1. Impact crusher can process materials with high humidity to prevent blockage
When the moisture content of the material is too large, the feed chute and impact plate of impact crusher will equipped with a heating device to prevent the material from sticking. Impact crusher does not require a bottom screen to prevent clogging. However, the hammer crusher cannot be heated to prevent the material from sticking and the bottom screen must be provided which increase the possibility of clogging.
2. Impact crusher is applicable for more materials
Impact crusher can be applied to both soft materials and relatively high hardness materials.
3. Impact crusher has wide adjustment ragne of feeding size
The mechanical adjustment device is arranged on the top of impact crusher. The spacing between the base frame and the rotor can be adjusted by twisting the bolt of the device, thereby adjusting the discharge size. Adjusting the rotor speed, spacing between the impact plate and the grinding cavity can also adjust the discharge size. The hammer crusher can only achieve the purpose of adjusting the discharge size by replacing the bottom sieve plate.
4. The spare parts of impact crusher has less wear and longer service life
The wear of the impact crusher hammer only appears on the side facing the material. When the rotor speed is normal, the feed material will fall to the surface of the hammer and the back and sides of the hammer will not be worn. Even the wear on the side of the material is scarce. And the bottom grinding rod is also easy to replace. The metal utilization rate of the hammer can reach 45% to 48%.
The hammer of hammer crusher has a suspended state and the wear occurs on the upper, the front, the rear and the side. The hammer wear is more serious, and the metal utilization rate of the hammer is only about 25%. Moreover, the rotor body itself may also be subject to wear. The bottom sieve plate of the hammer crusher is seriously affected by the wear, the barrier is completely replaced, and the work of replacing the sieve plate is also complicated.
5. Impact crusher spare parts replacement is simple with less maintenance costs
Only a few hammers are installed on the impact crusher rotor, and the replacement of the hammers can be conveniently carried out with special tools. The replacement of the bottom grinding rods can only take ten minutes, greatly reducing the time and cost of maintenance.
The hammer crusher has dozens of hammers. It takes a lot of time and manpower to replace a set of hammers. The maintenance costs are high and the replacement of the bottom sieve plate is also very troublesome.
Through the above points, we can see that although the costs of impact crusher is higher than hammer crusher in the early stage, it still has obvious advantages in performance and post-operation.
