Impactors
The impactors are metal bars that wear out very quickly and do 70% of the work. It is very important to check the height of the striker. If the height is below the specified value, the impactor must be turned over to start its second life.
The strikers can be made of different materials: manganese, chromium cast iron, martensitic with ceramic insert, chromium cast iron with ceramic insert.
Their resistance to abrasion is more or less random depending on the abrasion of the product.
Shock absorbers and shields
Shock absorbers with several shielding bodies made of a material with high wear resistance. They also wear out very quickly. There is a limit to how far the shielding should be used. If the limit is exceeded, the shielding must be replaced. The shielding is fixed on the horizontal side of the shock absorbers.
The wear of the shield has no impact on the quality of the production
Rotor
The rotor is equipped with a series of impactor that perform a rotation, which allows it by hitting and throwing the rock against the shock screens to achieve a crushing.
The rotor is in some way the centerpiece of the crusher.
