An impact crusher uses a high-speed rotor to collide with material,
crushing it. It is suitable for crushing medium-hard and lower-hard materials,
such as limestone, coal, and gypsum. Its operating principle is that the
high-speed rotation of the rotor strikes the material against the impact plate,
where it rebounds and collides with other materials, crushing it.

I. What is the function of the impact plate in an impact crusher?
1. Material impact and crushing. The impact plate receives the material
struck by the rotor and causes it to collide in the opposite direction,
accelerating material crushing. The high-speed rotation of the rotor strikes the
material against the impact plate, where it rebounds and collides with other
materials, thus crushing the material.
2. Improved crushing efficiency. Through its impact, the impact plate helps
increase material crushing force and improve crushing efficiency. The collision
between the impact plate and the rotor generates strong energy, breaking large
pieces of material into smaller particles.
3. Adjustable product particle size. The distance between the impact plates
can be adjusted to control the angle of collision between the material and the
plates, further affecting the final particle size. In some designs, the position
of the impact plate can also be adjusted to optimize the crushing process.
4. Prevent direct wear. The impact plate exerts a high impact force on the
material and is prone to wear after prolonged use. Therefore, the impact plate
is typically made of a highly wear-resistant material, such as high-chromium
alloy, to extend its service life.
II. How to Reduce Vibration in an Impact Crusher?
1. Proper Installation Foundation. The impact crusher's installation
foundation must be stable and solid, ensuring the equipment is installed
levelly. During installation, the ground foundation must support the weight of
the equipment and effectively absorb vibration. A good foundation can reduce the
impact of vibration during operation.

2. Balancing the Rotor. The rotor is the core component of the impact
crusher. Rotor imbalance can cause severe vibration during operation. Therefore,
during the manufacturing process, the rotor mass should be balanced, and dynamic
balancing technology should be used to correct it if necessary to avoid
vibration caused by imbalance.
3. Design of a Vibration Isolation System. Many impact crushers are
equipped with a vibration isolation system, which typically includes buffering
devices such as springs and rubber pads to absorb vibration and impact forces
generated during operation. These vibration dampeners can effectively reduce the
transmission of vibration to the ground and other equipment.
5. Adjust the crusher's operating parameters. If your impact crusher
experiences excessive vibration, try adjusting its operating parameters, such as
speed and feed rate, to optimize the crushing process. By adjusting these
parameters, you can reduce unnecessary shock and vibration.
