Columbia Steel introduces high output cone mantle
Columbia Steel Casting Company's new, patented cone mantle design offers improved crusher output, based on initial field trials. According to the company, 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.” He adds that early trials with customers in Canada and the Southwestern U.S. are promising, and Columbia looks forward to further testing.
According to Columbia Steel, 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%, and some in which wear life increased up to 300%. 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 are at the 2017 CONEXPO-CON/AGG show in Las Vegas, NV, Booth 30911, Central Hall, during the week of March 5-10. 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 and recycled materials producers with a wide range of replacement wear parts in a variety of alloys.

The all-new CASE TR340B compact track loader — operating at 90 horsepower with a 3,400-pound rated operating capacity — is the most powerful radial-lift CTL in the CASE lineup. Its all-new 8-inch LCD display improves on industry-leading CASE visibility with a new backup camera that is viewable in both forward and reverse operation. The display also showcases critical operating information and "trip" details. All-new electro-hydraulic controls, managed through the display, make it easier than ever for operators to dial CASE CTLs into specific application demands. All new cab controls and joysticks make the new TR340B easy to own and operate.
Industries such as construction, mining, energy, utilities and forestry, face many challenges when it comes to tracking assets and employees. Equipment often has to be transferred between locations, or monitored while it is dormant during off seasons. Lone workers may have to travel long distances or visit multiple sites during the course of their activities. And, all of this is further complicated today with shifting supply chains and economic realities putting further strain on the bottom line.
