IMPACT CRUSHER WEAR PARTS
An impact crusher uses impact energy to break materials. During operation, the motor drives the rotor at high speed. Material enters the hammer action zone and is struck against the impact plate. After repeated impacts, rebounds, and re-crushing, it gradually moves from the large chamber into the smaller chamber until it reaches the desired particle size and is discharged.

As a key piece of equipment in aggregate production, construction, and construction waste disposal, the impact crusher's core wear-resistant components are the hammer and impact plate. SF is made of high-chromium alloy and undergoes special processing and heat treatment to achieve both high hardness (HRC60 and above) and excellent toughness, making it suitable for a wide range of demanding working conditions.

  • Impact Crusher Wear Parts

  • The plate hammer is the core wearing part of the impact crusher that directly strikes the material. This forged thick metal plate, typically high-chromium steel, is mounted on the rotor and rotates at high speed to deliver the initial crushing force. Its robust impact resistance and wear resistance make it the primary executor in crushing asphalt, concrete, limestone, and other materials.
  • The Impact Block (also known as the grinding block or third impact rack) is the final barrier in the multi-stage crushing chamber of an impact crusher, responsible for the final crushing and precision shaping of materials. It further restricts and grinds oversized particles through a narrow grinding channel, ensuring uniform output size and excellent particle shape.
  • The impact liner plate and rotor are the two core components that work in synergy within an impact crusher, forming a highly efficient impact crushing chamber. The rotor is the "heart" that transmits kinetic energy and drives the plate hammers for the initial impact, while the liner plate is the "strategic wall" responsible for secondary crushing and final product shaping. Their perfect coordination is the key to ensuring crushing efficiency, product shape, and equipment stability.
