A tertiary impact crusher is a type of crusher used in stone crushing plants, specifically designed for fine material production. The term "tertiary" refers to its use in the third stage of crushing, where materials are processed to achieve smaller sizes. Tertiary crushers use high-speed rotating rotors and impact plates to break down the material into desired particle sizes.

Key Features of Tertiary Impact Crushers

  • Fine Material Production: Ideal for producing small sizes such as 0-5 mm or 5-10 mm.
  • High Capacity and Efficiency: High-speed rotors ensure the material is crushed quickly and effectively.
  • Adjustable Output Sizes: By adjusting impact plate angles and rotor speeds, the desired particle size can be achieved.
  • Low Maintenance Cost: Built with durable parts, these crushers are long-lasting, but regular maintenance can improve efficiency.

Applications

  • Concrete and Asphalt Production: Commonly used where fine material is required for concrete or asphalt.
  • Mining and Quarries: Used in the fine crushing stage for hard stones.
  • Road Construction: Often employed for producing materials for road base layers.

Tertiary impact crushers are ideal for projects that require finer material as they break down material using high-speed impact, producing a finer output compared to other crusher types.
