Secondary impact crushers are highly efficient crushing machines used in quarries, mining, and recycling plants. They reduce the material from primary crushers to smaller and more uniform sizes, improving the final product quality. These crushers are commonly used for breaking medium-hard and hard materials such as limestone, basalt, dolomite, and granite.

Working Principle:

  1. The material enters the feeding chamber and is thrown against a high-speed rotating rotor.
  2. Due to the impact, the material shatters and breaks.
  3. The broken material collides with impact plates and further reduces in size.
  4. Adjustable crushing plates ensure the desired particle size is achieved.

Advantages:

  • High crushing ratio and efficiency
  • Low maintenance costs
  • Adjustable output size
  • Wear-resistant components
