Our customer operates a stone quarry in Serbia. They use the GM Impact Crusher produced in Turkey. After running for a while, the customer found that the accompanying blow bar was not very wear-resistant, so they replaced it with a blow bar produced in the Serbian factory. The result was still the same. Not wear-resistant.
After communicating the working conditions in detail, we designed TIC insert blow bars for him.

Background

Machine: General 800 Mobile Crusher

Working conditions:

Challenges

Customer feedback: Whether it is the blow bars produced in Türkiye or Serbia, the span life is not good, just around 15 days per side. The service life is short, the replacement cycle is fast, which affects production capacity, and the replacement cost is high.
