1. Different crushing cavity
The crushing cavity of the impact crusher is large, and the feeding port is low and large. The crushing of the material not only depends on the impact of the hammer, but also uses the repeated impact between the material and the impact plate or between the material and the material, and the impact crushing effect is more sufficient. , so as to better break up large pieces of material. The hammer crusher has a smaller crushing cavity and good structural sealing performance, which solves the problems of dust pollution in the crushing space and ash leakage from the body.
2. The wearing parts are different
The plate hammer and the hammer head are the main wearing parts of the counterattack and hammer respectively. The wear of the blow hammer of the impact crusher mainly occurs on the side facing the material, and the metal utilization rate of the blow hammer can reach 45%-48%. The hammer head of the hammer is in a suspended state, and the wear occurs on the upper, front, rear and side surfaces. Compared with the plate hammer, the wear of the hammer head is more serious, and the metal utilization rate is about 35%.
3. The direction of action of the plate hammer/hammer head is different
The plate hammer of the counterattack crusher meets the material from bottom to top for crushing operation, and throws the material onto the counterattack plate above. The hammer crusher is crushed in the direction in which the material falls. The counter-rotating rotor rotates clockwise, the plate hammer faces the material from bottom to top and the rotor rotates counterclockwise, and the hammer head strikes the direction of the material falling.
4. Different rotor links
The plate hammer and the rotor of the impact crusher are rigidly linked, that is, the plate hammer is fixedly installed on the rotor, and the inertia of the entire rotor can be fully utilized to impact the material during crushing, which not only crushes the material, but also has great speed and speed. kinetic energy. The hammer head of the hammer crusher crushes the material individually (the hammer head is in a suspended state), and has limited speed and kinetic energy.
5. Different discharge adjustment methods
There is no grate screen in the lower part of the impact crusher, and the adjustment of product particle size can be controlled by adjusting the rotor speed or rotor diameter, adjusting the opening size of the distributor, and adjusting the gap of the grinding cavity. The hammer crusher controls the product particle size by adjusting the size of the sieve plate gap. Therefore, when dealing with materials with a large water content, the impact crusher can avoid the phenomenon of clogging the grate when crushing wet materials, which is more advantageous.
