Blow Bars

Description :

Blow Bars : Blow bars are thick metal slabs that are used to break down materials like concrete, asphalt, and limestone in an impact crusher. They are usually made from a mixture of chrome and are inserted into the rotor of the crusher in sets of three or four. 

Blow bars strike the material entering the crushing chamber, throwing it against the impact wall and causing it to fracture into smaller particles. In the process of striking the material, blow bars wear out and need to be replaced. 

The amount of chrome in the blow bar's design is directly related to its effectiveness in bearing up against abrasive materials. Different materials are used for blow bars depending on the application, including:

 High manganese

-A good choice for crushing less abrasive and large feed material, such as limestone
