Metso sells spider rotor - Equipment Report - to Advanced Recycling - Brief Article

Recycling Today, April, 2003

Metso Minerals Metal Recycling's North American operations, based in Cedar Rapids, Iowa, has announced the sale of a shredder "spider-style" rotor.

Advanced Recycling of Concord, N.H., purchased the rotor, which incorporates Metso Minerals' four-pin spider design featuring fully capped protection of the spiders and end discs. The rotor will be installed in Advanced Recycling's Metso Minerals 6080 Scrap Shredder.

Company engineers say the benefits of the fully capped design include increased rotor longevity and that no welding is required throughout the lifetime of the rotor.

Bill Tigner, North American vice president and general manager, remarks, "This rotor assembly delivers 500,000 to 1 million tons or more of rotor life to many Metso Minerals Metal Recycling customers--much more than competitive designs available on today's market."

The manufacturer claims it is the most aggressive, most easily fed rotor design available on the market today. Spider rotors can process through unshreddables that can leave some other rotors with broken grates, stretched bearing studs or other types of damage.

Besides complete replacement rotors, Metso Minerals also offers a line of shredder parts including hammers, spider caps, grates and liners.
