The Role of Blow Bar in Impact Crushers. In an Impact Crusher, the blow bar is mounted on the rotor and rotates at high speeds. When the rotor spins, the blow bar strikes the material fed into the crusher, causing it to shatter and break down into smaller pieces. The impact force generated by the blow bar is what facilitates the crushing process.

The highest wearing parts of the ® horizontal shaft impact crusher are the: Rotor blow bars (manganese or chrome iron) Apron liners (manganese) Frame liners (abrasion-resistant steel) To extend the wear life of the blow bars, they can be flipped around once one side is worn out. This rotation can be done before needing to replace the ...
Wear limit for blow bar replacement . The blow bars on a NP impact crusher are reversible. When one side is worn out, the blow bar can be rotated so that the other side can be used. To avoid any damage due to wear, the wear limit indicated by the letter D on below draft should be lower than the values shown in the table hereunder.
Remove the blow bar positioning parts, then press and remove them axially, and then push the blow bar axially from the maintenance door, or lift it out with a rack. In order to facilitate the disassembly of the blow bar, you can hammer the blow bar on the blow bar with your hand.
Blow bars are used in horizontal shaft impact crushers by inserting them into the rotor. During operation, the rotor spins at high speeds and strikes the material to be crushed repeatedly. The type of crusher blow bar selected for each operation has a direct influence on the productivity of the impact crusher.
The impact crusher blow bars are also known as hammers because of their primary function. Its blow bars are made into large and very thick slabs of alloy or other metal composites. Each impact crusher has three to four sets of blow bars in the machine. They are inserted into its rotor where they strike the different kinds of material that need ...

Although the rotor is the most important component in your HAZEMAG impact crusher, the impact bars are the primary crushing tools. Essentially, the impact, or blow bars, absorb the crushing impact forces but, for this to work effectively, your HAZEMAG impact crusher must be properly operated and maintained. Relevant influencing factors include ...
Martensitic blow bars have better impact resistance than chrome blow bars and better wear life than manganese steel blow bars. With the ceramic inserts on the wear face, the working life of the martensitic blow bars can be largely increased. Normally, the martensitic/ceramic blow bar has twice as much wear life as the pure martensitic blow bar.
"When the high bars wear down to about the level of the low bars, we remove the most worn set and install new high blow bars. The worn-down bars now act as the dummies," Weber explains. Another ...

Blow bars are a critical part when it comes to crushing with Horizontal Shaft Impactors (HSI). Whether you call them breaker bars, blow bars, hammers or impact hammers, they are all the same. They impart the energy into the material and accelerate it into the curtain or apron, causing the shattering and crushing of the material.
What are Blow Bars? Blow bars are thick slabs of metal, typically some mixture of chrome, that are forged for the purpose of effectively breaking apart material like asphalt, concrete, limestone, etc.. Blow bar is a critical part during the crushing process with horizontal shaft impactor.Materials of the blow bars are usually selected according to the function of the impact crusher.
