The working principle of an impact crusher involves the utilization of impact rather than pressure to crush materials. Here’s a step-by-step explanation of how it functions:
Feeding: The material is fed into the impact crusher through a hopper.
Rotation: Inside the crusher, a high-speed rotor equipped with hammers or blow bars rotates at a high speed.
Impact: When the material enters the rotor area, it is struck by the rotating hammers or blow bars. This impact causes the material to break into smaller pieces.
Secondary Impact: The broken pieces are then thrown against the impact plates or breaker plates inside the crusher chamber. These plates are typically made of wear-resistant material. This secondary impact further reduces the size of the material.
Ejection: Once the material reaches the desired size, it exits through the bottom of the crusher.
Adjustment: The size of the output material can often be adjusted by changing the rotor speed, altering the path of the material within the crusher, or adjusting the distance between the impact plates.
Impact crushers are popular in industries such as mining, quarrying, and recycling due to their ability to produce a uniform particle size and their efficiency in breaking down a wide variety of materials.
