How Impact Crusher to Work?

Structure and Features of Impact Crusher

Impact Crusher mainly consists of rotor, impact frame, mainframe, ratchet cover and transmission parts.

Rotor of Impact Crusher
The rotor frame of Impact Crusher is welded by steel plate. The hammers are fixed on right place. Lateral stop can effectively avoid the movement of the hammers.
The hammers are made of abrasion-resistant material. The whole rotor has good balance and resists impact.

Mainframe of Impact Crusher
The mainframe of Impact Crusher consists of seat, middle box-frame, and back cover, which are jointed by special bolts. The back cover adopt ratchet device, it is safe when the worker replaces the easily damage parts. It is more convenience to examine, repair the machine and replace the easily damage parts if the user equipment hoist over the mainframe. There are two repair doors on the two sides of the mainframe.

Impact frame of Impact Crusher
In the Impact Crusher there are two impact frames ---front impact frame and back impact frame. Each impact frame is separately suspended in the mainframe. When the Impact Crusher is running, the impact frames keep the normal position by the gravity. When something that cannot be crushed enters into the machine, such as metal, the impact frame will rise up, discharge the metal, and come back. The distance between impact frame and rotor can be adjusted by the bolts. The impact plates can be replaced from the serious abrasion place to the less abrasion place.

Transmission of Impact Crusher
The rotor is driven by V-belt. The pulley attached with main shaft is joined with taper sleeve, so it is easy to be disassemble. The speed of rotor is adjusted by changing grooved pulley.

Ratchet cover of Impact Crusher
There are two ratchet covers in the both sides of the mainframe. It is easy to open and close for inspection of machine.

Working Principle of Impact Crusher

Impact Crusher is a crushing machine that uses the impact energy to crush stuff. When the stuff enters the field of the hammer, it is impacted by the hammers, thrown onto the impact plate, and crushed. The stuff springs from the impact plate, is impacted by the hammers again, and thrown onto impact plate. This process will last until the stuff meets the requirement and falls from the machine. Adjusting the distance between impact frame and rotor frame can change the shape and size of the output.

When some stuff that cannot be crushed enters the Impact Crusher, the impact frame will fallback, the stuff falls from the machine. This device can guarantee the Impact Crusher cannot be damaged.
