Impact crusher and hammer crusher are often compared as ore crushing equipment. We will distinguish between impact crusher and hammer crusher.
Impact crusher and hammer crusher are often compared as ore crushing equipment. We will introduce it from the equipment itself. Impact crusher can be used for rough and medium-sized materials such as ore and rock with compressive strength not exceeding 350MPa. And fine crushing operations, widely used in the construction of roads, railways, water conservancy, power, construction and other industries for the production of sand and gravel. The hammer crusher is suitable for mining, building materials, chemical, metallurgy, feed and other industries. It can be used for medium and fine crushing of barite, limestone, terrazzo, and other materials with medium hardness. It is not clear from these aspects that they are fundamentally different. Below we make a detailed introduction from the design structure, working principle and scope of use.

  1. The impact crusher consists of rotor, impact plate, frame, impact plate, stern plate, and transmission parts. The impact plate is rigidly connected to the rotor. The hammer crusher pool consists of rotor frame, crush plate, sieve plate, and box. The body, the hammer head, and the transmission are not formed. The hammer head is hung on the hammer frame.
  2. The impact crusher does not have a screening structure such as caster rods, and the size of particles is sorted by adjusting devices, while the hammer crusher controls the fineness of the stone particles by the caster rods.
  3. The impact crusher uses the inertia of the entire rotor to impact the material. The material gains a large speed and kinetic energy. The plate hammer strikes the material against the upward trend, and the crushing effect is large. The hammer crusher uses a single hammer to crush the material. Impact crushing, so the speed and kinetic energy obtained by the material are limited, and the hammer head strikes the material downwards, and the crushing effect is small.
  4. The crushing cavity of the impact crusher is large, so that the material has a certain space for movement, making full use of the impact, while the hammer crusher is just the opposite, so the impact crusher is not enough to crush.
  5. The impact crusher is mainly determined by the rotor speed and the gap between the outer edge of the rotor and the screed plate. The grain size of the finished product is 80% less than 30mm. The grain size of the product is controlled by the width of the gap between the purlins. The grain size of the finished product varies depending on the model.
  6. Impact crushers are mostly used as secondary crushing equipment, while hammer crushers are used as primary crushing equipment in sand and gravel production lines.
