The hammer crusher uses the impact action of the rotary hammer head of the rotor to crush brittle or medium hardness materials, but cannot be used to crush materials with high toughness, fiber quality and temperature. Hammer crusher is used to crush all kinds of medium hard and weak abrasive materials.

The advantages of  hammer crusher are: large crushing ratio (generally 10-25, up to 50), high production capacity, uniform product, less pulverization, low energy consumption per unit product, simple structure, light equipment quality, easy operation and maintenance, etc. It can crush raw materials of different sizes into uniform particles to facilitate the next process. It has reliable mechanical structure, high production efficiency and good applicability.
