Cone mantle field trials look promising for high-output design featured at CONEXPO.

Columbia Steel's patented high-output cone mantle design
PORTLAND, OR – FEBRUARY 2017 – A new, patented cone mantle design offers improved crusher output based on initial field trials, reports Columbia Steel Casting Co., Inc. By looking beyond the concept of simple gravity feeding, Columbia’s engineers have developed a unique mantle modification intended to direct feed more efficiently into a crushing chamber.

“We’ve found that filling a crushing chamber via typical gravity feed may not provide optimum, or maximum, material flow,” says Steve Dolezal, Columbia Product Engineering Manager. “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 U.S. are promising, and Columbia looks forward to further testing. “I would encourage anyone at CONEXPO who is interesting in learning more about our high-output mantle to visit with me personally at the show,” adds Dolezal. “Bring us your questions, and let’s see if this mantle could make a difference in your productivity.”

This same problem-solving focus is applied to jaw and gyratory crusher wear parts, as well. Columbia engineers design crushing surfaces to improve production and product sizing, while lowering discard weight and overall operating costs. Alloys are tailored to meet the level of impact and abrasion encountered by customer equipment, resulting in better overall plant performance.

Columbia Steel offers more jaw crusher plate styles than any other single manufacturer in the industry. Customer feedback has proven that the right jaw plate design can make a dramatic difference, depending on the application. Case histories reveal wear life increases of 50 percent, and some in which wear life increased up to 300 percent. A gyratory wear part study by a Columbia engineer or field rep can reveal many areas for potential improvement: poor nip of feed materials, excessive wear in lower crushing chambers, poor throughput from partially worn parts, significant wear metal discard costs, and problems with uneven or localized wear.

Columbia Steel’s engineers and field reps will be at the 2017 CONEXPO-CON/AGG show in Las Vegas, NV, Booth 30911, Central Hall. The company is headquartered in Portland, Oregon, USA. Its 86-acre facility is home to an on-site product design and engineering department and full-service steel casting foundry. Columbia Steel serves aggregate producers with a wide range of replacement wear parts in a variety of alloys.
