The surge in power battery recycling is having a significant impact on the market. Data from the China Automotive Technology and Research Center (CATARC) shows that the cumulative amount of scrapped power batteries in China reached 200,000 tons in 2020. In the future, the scale of retired batteries will continue to increase, making the proper handling of retired power battery recycling an urgent matter.
Recently, the American company BCA Industries (BCA) launched a technology that can efficiently shred battery materials, helping recycling companies increase production capacity while saving energy costs.
It is understood that BCA's patented Triplus blade system technology, which uses a bottom blade design in a dual-shaft shredder, can cut materials to any width in one go without the need for a sieve.
A shredder with this design can bring more than 85% of materials to the appropriate size in one pass, while the proportion of oversized materials is less than 10%. In addition, for very large batteries, or batteries containing hard metal components such as metal casings or rods, a separate primary shredder is required.
It is understood that, unlike many other methods that use shredders to gradually reduce the size of battery waste, the new shredder's "blade" technology can uniformly cut batteries into any size in one go, preventing smaller batteries from "slipping" through the shredding chamber. This method quickly transforms battery waste into recyclable sizes while preventing thermal runaway and coolant fires, significantly shortening the processing and maintenance process, and reducing energy consumption and labor.
BCA explains that using this shredder system, a single 50-horsepower shredder can produce the same amount of recyclables per hour as a standard 100-150 horsepower conventional system. This not only helps recyclers reduce energy costs by $1,500-$5,000 per month, but also produces more uniform products.
