Quad Plus, Joliet, Ill., has installed what it’s calling the first DC shredder drive in the United Kingdom at Hawkeswood Recycling in Birmingham, England.
The 4,000-horsepower, 24-pulse DC shredder drive powers an 80/104 automobile shredder made by American Pulverizer, St. Louis.
According to a Quad Plus news release, the DC shredder drives can be viewed as preferable by power companies because they can limit voltage fluctuations that cause “flicker.” The issue is relevant to sites across Europe that face the same power quality issues, says Joseph Crosetto of Quad Plus.
Other differences that Hawkeswood Recycling will notice with a DC drive, according to Quad Plus, are its ability to run at any speed; that it can jog forward and reverse to clear jams; and an electronic brake to stop the mill. According to Crosetto, DC motors also maintain 100 percent of their torque down to zero rpm, making jams less likely.
Quad Plus has installed more than 60 DC shredder drives, primarily in the United States but also in Mexico, Canada and Australia, says Crosetto.
