Impact crusher and hammer crusher are often compared, so what's the difference between them?

First, let's talk about the hammer crusher. The obvious advantage of traditional hammer crusher with grid section and sieve plate is large capacity, so as to reduce the number of machines and form a shorter production line. However, this hammer crusher also has a very fatal disadvantage: it uses the hammer head to crush the materials, and adjusts the stones’ size through the sieve plate. It sounds like nothing wrong, but in fact, the hammer head is hinged on the rotor, with small weight, limited kinetic energy and small crushing effect on the materials, resulting in invisible cracks in the stones, insufficient internal strength and more stones shaped like needles and flakes. In addition, in recent years, some new hammer crushers appeared in the market, some of which are also called heavy type hammer crusher. In order to obtain greater production capacity, they even directly cancelled the grid section and sieve plate. Although this rough method can improve the capacity, it reduces the crushing efficiency and significantly increases the stones’ size. Users have to continue to increase equipment to crush a large number of returned materials in the subsequent process, which weakens the previous advantages of hammer crusher.

Then let's talk about impact crusher. The plate hammer is rigidly connected with the rotor, and the inertia acts on the stone completely, so the energy loss is small, and larger speed and kinetic energy can be obtained. The crushing effect is large, and the materials are completely crushed along the fragile layer, avoiding hidden cracks, maintaining the internal strength of the aggregate. At the same time, the stones’ shape is good, and the proportion of cube finished products is large. It can be said that impact crusher is obviously better than hammer crusher in energy consumption, particle size, aggregate strength and service life of vulnerable parts.

The CI5X impact crusher of Liming Heavy Industry has advantages of large capacity and easy maintenance. The finished stones have high strength and good particle shape. It is a popular product in the market recently. If you want to own such a machine, please contact us immediately.
