Impact crusher and hammer crusher are relatively similar in appearance, and both belong to the percussive crusher, so many customers are not quite able to distinguish these two kinds of equipment. So, here is an introduction to the respective characteristics of these two crushers to help you distinguish and purchase.
The main difference between impact crusher and hammer crusher is in the following aspects:
1. Materials: Impact crusher for wet materials can also be processed, but you can no longer configure the screen plate, so as to avoid equipment clogging problems, and in the impact crusher between the inlet and the impact plate to add a heating device to prevent the wet material bonding, it will be more likely not to cause the machine clogging; Hammer crusher for wet materials is not recommended to deal with. Impact crusher adopts fixed rotor structure, the rotor’s inertia can bring more power for the machine, so that the impact crusher equipment in the crushing of hard materials, more seem to be handy, and the unit of energy consumed is completely less than the hammer crusher.
2. Flexibility of the equipment: impact crusher can be adjusted by adjusting the speed of the rotor, the grinding chamber of the mobile space and other ways to determine the size of the machine’s discharge particle size, flexibility is greatly enhanced, and in this regard, the flexibility is much higher than the hammer crusher.
3. Equipment components: impact crusher simple structure, less wearing parts, its rotor is installed on eight hammers, relatively speaking, the hammer crusher has more than 100, the maintenance cost of equipment components and the amount of work, impact crusher than hammer crusher is much simpler, and impact crusher wearing parts utilisation rate is higher, wear and tear range is smaller.
4. Principle: Impact crusher relies on the plate hammer to impact and crush the materials into the crushing chamber from the bottom upwards, and throw the materials to the impact plate to be crushed again; while the hammer crusher is to strike and crush the materials along with the direction of the falling of the materials into the crushing chamber.
5. Application scope: Impact crusher can crush large and hard materials, and also can deal with the logistics of high water content, while the feed material of hammer crusher is generally less than 400mm, which is suitable for dealing with small pieces of less hard logistics.
6. Discharge strength adjustment: Impact crusher can adjust the discharge size through various ways, this will not expand, while the hammer crusher’s discharge size adjustment mainly rely on the replacement of the grate plate.
7. Load and wear: the load of the impact crusher is mainly in the plate hammer, so only one side is easy to wear, and the wear rate is relatively low, while the hammer head of the hammer crusher is to be repeatedly pounded on multiple sides, so the wear and tear is relatively fast.
To sum up, there are obvious differences between the impact crusher and the hammer crusher in terms of the materials to be processed, the flexibility of the equipment, the equipment components and the crushing principle, etc. These differences make the two types of crushers more suitable for practical use. These differences make the two types of crusher have their own focus in the actual application, users should choose the appropriate equipment according to the specific crushing needs and material characteristics.
