CM Introduces the New Hybrid Primary Shredder
Columbus McKinnon Corporation, the world’s leading manufacturer of tire shredding equipment has developed new shredding technology to adapt to the ever changing markets in the tire recycling industry as well as expand into new markets beyond tires.
Since entering into the business in 1982, all CM tire shredders have exclusively used Holman™ patent technology or fixed rotor technology for the reduction of tires. This technology creates very close knife to knife tolerances that are within .001 -.002 of an inch that allows the machine to produce cleanly cut tire chips. The superior quality produced from this type of cut has always been preferred when making a TDA or TDF product. However, with the growth of the Crumb Rubber Industry shredder requirements are quickly evolving. Shredders within these applications are used for volume reduction to prepare the tire for additional processing allowing for other cutting technologies to be considered.
The CM Hybrid Shredder is a primary shredder that was developed for multiple uses within the tire industry as well as other applications. By using removable rotor technology the machine becomes a “Hybrid.” The machine now boasts a new “Stack and Go” system that can use the CM Holman™ patent technology that has been adapted to a removable rotor which works well for tire applications as well as other applications where close cutting tolerances are required. It also accepts single piece shear shredder knives that are common for shredding general waste applications. This combination allows the machine to be versatile within the industry.
CM engineers have also developed new knife group locking technology and advanced bearing protection to enhance the machines performance. The “CM Secure Lock” system allows the bearings to be located outside of the shredding envelope for better protection and is no longer used to secure the knife group.
CM has sold its first Hybrid Shredder to one of the leading US scrap tire processing companies. The shredder is on its way to their facility and will be operational by years end. The Hybrid Shredder will process a wide range of tire sizes using its unique combination of CM knives and hook shear combination for powerful pre-shredding applications.
The CM Hybrid Shredder can accept whole passenger car, SUV, light truck, heavy duty truck, super singles and small OTR tires.
