Gerdau Extends Shredder Component Life with LINDEMANN Double Grate Technology
Gerdau Extends Shredder Component Life with LINDEMANN Double Grate Technology
30% Longer Wear Life and 40% Faster Maintenance for Improved Scrap Recycling Performance
As the largest metal recycler in the Americas, Gerdau continuously seeks opportunities to improve operational efficiency across its recycling and steelmaking operations.
At its Usina Riograndense facility in Brazil, the company partnered with LINDEMANN to optimize shredder performance through the implementation of innovative double grate technology.
The Challenge
Wear components play a critical role in shredder productivity and availability. Frequent maintenance shutdowns, component replacements and extended service intervals can significantly impact production efficiency and operating costs.
Gerdau was looking for a solution that could:
- Extend component lifetime
- Reduce maintenance duration
- Improve workplace safety
- Increase overall shredder performance
The Solution
Together with LINDEMANN, Gerdau launched South America’s first double grate shredder project. The new grate configuration not only increased grate durability but also improved hammer wear distribution and overall shredder efficiency. The redesign simplified maintenance procedures and significantly reduced replacement times.
The Results
The pilot project delivered impressive results:
-
30% longer grate lifetime
-
230,000 tons processed per grate set compared to 180,000 tons previously
-
40% reduction in maintenance time
-
Reduced equipment downtime
-
Improved workplace safety
-
More homogeneous hammer wear
-
Increased operational efficiency
