Scope of application: The impact crusher can handle all kinds of coarse, medium and fine materials (granite, limestone, concrete, etc.) with side length no more than 500mm and compressive strength no more than 350MPa. It is widely used in hydropower, expressway, artificial aggregate, Broken and other industries. Features: Impact crusher unique structure, keyless connection, high chrome plate hammer, a unique counterattack lining; hard rock crushing, energy efficient; shape of the product was a cube, discharge size adjustable particle size to simplify the crushing process. Working principle: When the impact crusher works, driven by the motor, the rotor rotates at a high speed. After the material enters, it collides with the slab hammer on the rotor to crush, then it is countered and crushed again to the lining plate, finally discharged from the discharge opening .
