How Does a Hammer Crusher Work？

A hammer crusher, also known as a hammer mill, reduces material size through impact. High-speed rotating hammers within the machine strike the material, causing it to break against a breaker plate and screen, ultimately producing smaller particles. 

Here's a more detailed breakdown of the process:

1. Feeding:

Material is fed into the crusher's chamber, typically through a chute. 

2. Impact:

The material enters the path of rapidly rotating hammers, which are attached to a rotor. 

3. Crushing:

The hammers impact the material, breaking it down. The material also collides with the breaker plate and other particles, further reducing its size. 

4. Screening:

A screen or grate at the bottom of the chamber retains larger pieces, preventing them from being discharged until they are small enough to pass through the openings. 

5. Discharge:

Smaller particles that pass through the screen are discharged as the final product.
