Large quantities of production experiments prove that the impact crusher has the following special and distinctive features compared with other types of crushing machines:

impact crusher

1. When the impact crusher crushes the materials, it is able to make full use of the energy of the whole rotor, for this reason, it has a very high crushing ratio and it can be used as coarse, medium and fine crushing equipment. In this way, it will simplify the crushing flow, save equipment and infrastructure construction investment and reduce the maintenance expenditure.

2. The impact breaker makes use of the plate hammer with high rotary rate to impact the materials, and there is every chance for the materials to be crushed along the border of the crystallization and the texture, for this reason, the dynamic energy consumed by the materials during the crushing process will be saved significantly.

3. This impactor crusher has a strong adaptability, and it can be sued crushing all kinds of medium hard, soft, crisp and tough and fiber materials, and the granularity of the crushed products is in the shape of cubic and very even, and it is widely used in the industrial departments.

4. This crushing machine has many advantages such as simple structure, light weight, small size, low operational cost, safe operation and convenient manufacturing and repair.

5. While it is working, there is no remarkable imbalanced vibration and there is no need of heavy foundation.

However, it also has its own shortcomings. It is not suitable for crushing plastic and sticky materials. If it is used for crushing hard materials, the abrasion of the plate hammer will be serious.

The reasons why the impact crusher is seldom used for coarse crushing are as follows:

1. The maximum line velocity of the plate hammer of the impact crusher can reach 50m/s, so that it will be seriously damaged during the crushing process.

2. When crushing big-sized materials, the energy consumption for unit ton will exceed that of the crushing equipment using pressing energy with the same production capacity.
