Updated double beam shredder grates

These updated double beam shredder grates are designed to match current industry demands, which are putting big pressure on equipment and operators to process even the most unwieldy scrap with maximum efficiency and profitability. They feature added strength, with rigidity that reduces flexing and bowing, and changes to features like grate openings, which are staggered on this design, so there is one beneath each hammer track for more throughput volume. “Customers are shredding materials that might have been unthinkable 10 years ago,” says Columbia Steel product engineer Greg Stegmaier. “The biggest benefit of a double beam design is its added strength. The beams’ rigidity reduces flexing and bowing under service. Bowing is as bad as excessive wear, because feed material isn’t effectively shredded between the hammers and grates.” “We have an East Coast customer who jumped from 70,000 tons to 200,000 tons of scrap processed between grate change-outs,” continues Stegmaier. “That same operator also described our double beam product as ‘the easiest grate to pull out’ when a change-out was finally needed – a real plus in a safety-conscious industry.”
