The impact crusher is an efficient crushing equipment. The ore is fed in from the feed port and slides down onto the screen. The ore on the screen is crushed by the carbide hammer on the high-speed rotating rotor during the falling process and flies in a tangential direction at a high speed. The first counterattack board continues to crush the ore. The counterattack board knocks the ore back and collides with other ore thrown behind the rotor.
After the ore is crushed to a certain degree in the first crushing chamber, it is discharged into the second crushing chamber through the gap between the impact plate and the rotor and continues to be repeatedly hit until the particle size becomes smaller before being discharged from the discharge port at the bottom of the crusher.
Advantages and Disadvantages of the Impact Crusher
The Main Advantages of the Impact Crusher:
- Simple structure, small size, light weight, and large production capacity.
- The ore is broken along the joint surface, so the power consumption is low and the efficiency is high.
- The crushing ratio is large, up to 40, which simplifies the crushing process.
- It has a selective crushing effect, and the particle size of the crushed products is relatively uniform, and the shape is mostly cubic.
The Main Disadvantages of the Impact Crusher:
- The hammerhead and the impact plate wear quickly.
