Tertiary impact crushers are crushing machines specifically designed for producing fine materials. They are typically used after secondary crushing to refine the material into smaller and more uniform sizes. These crushers are widely used in fine aggregate production, concrete and asphalt manufacturing, mining, and recycling industries.

Working Principle:

Tertiary impact crushers break the material by compressing it between a high-speed rotating rotor and impact plates. The crushing process occurs as follows:

  1. Feeding: The material enters the feeding chamber.
  2. Impact and Breaking: The high-speed rotor throws the material into the crushing chamber using hammers or special plates.
  3. Repeated Impact: The material collides with fixed and adjustable impact plates, further reducing its size.
  4. Desired Size Output: The adjustable plates allow the material to be crushed to the required size.

Advantages:

  • High precision and fine crushing capability: Produces small and homogeneous particles.
  • Adjustable impact plates: Allows customization for different material types.
  • Low maintenance cost: Durable, wear-resistant components ensure long-lasting use.
  • Energy efficiency: Delivers high performance with lower power consumption.

Tertiary impact crushers are essential for producing high-quality sand and fine aggregates.
