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:
- Crushed material: Limestone
- Input size: ≥800 mm
Used blow bars: Mn18Cr2 blow bars
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.
Solution
Qiming Casting designs new material blow bars for him. （TIC+Mn18Cr2MoNi）
Customer Feedback & Results
After our product ran for 15 days, the customer conducted regular inspections and maintenance:

60 days later, the Customer gave us feedback: “TIC blow bars for GM met expectations, two months one side, that’s about 70-80% more than previously used.”
