Impact Crusher vs Hammer Crusher

First let's take a look at the hammer crusher. Hammer crusher has shed bars, screen plate of the traditional hammer crusher, the significant advantage is that it can be made very large, thus reducing the amount of production line equipment, composed of a shorter production line. But the hammer crusher also has a very fatal disadvantage. It utilizes the hammer head to impact and crush the material, and adjusts the discharge size through the screen plate. Obtain the desired finished product. Because the hammer head is hinged on the rotor, the weight is relatively small, the kinetic energy is also limited, the crushing effect on the material is small, so that the stone material produces invisible cracks, the internal strength is not enough, the particle size of the needle flake will also be more.

Later the birth of a new hammer crusher, similar to it, also called heavy hammer crusher. In order to obtain greater capacity, the new hammer crusher even directly canceled the shed bars and screen plates. Although this rough way to improve the output, but further reduce the effectiveness of crushing, the size of the discharge material is also significantly increased. Users have to continue to add equipment in the subsequent process, a large number of return material for crushing. In this way, in turn, the most basic advantages of the hammer crusher is weakened.

Next, let's learn about the impact crusher. Impact crusher's plate hammer and rotor are rigidly connected, inertia all act on the stone material, energy loss is small, the speed and kinetic energy gained by the material is relatively large, the crushing effect is also large, the material along the fragile level of complete crushing, to avoid the appearance of invisible cracks. Both the internal strength of the aggregate is maintained, while the granularity of the discharged material is better. The proportion of cubic finished products is very large. It can be said that the impact crusher is significantly better than the hammer crusher in terms of energy consumption, particle size, aggregate strength, and wear parts life. Of course, if you want to simply crush the low hardness of the brittle materials, the output is not big, you can choose to invest in the relatively low cost of the hammer crusher.
