The high-output mantle design was featured at CONEXPO in Las Vegas, Nevada, US last week.

By looking beyond the concept of simple gravity feeding, Columbia’s engineers have developed a mantle modification that is intended to direct feed more efficiently into a crushing chamber.

Steve Dolezal, product engineering manager at Columbia Steel, said: “We’ve found that filling a crushing chamber via typical gravity feed may not provide optimum, or maximum, material flow. Our high-output mantle design works by consistently drawing material into the chamber, producing a higher volume of crushed product.”

Early trials with customers in Canada and the southwestern US are promising, and Columbia looks forward to further testing.
