Multifunctional Hybrid Primary Shredder

Multifunctional Hybrid Primary Shredder

The CM Hybrid Primary Shredder is engineered to process passenger car, truck and super singles as well as farm, off-road and pre-cut mining tires. The Hybrid comes equipped with twin 75-horsepower (150 kW) gear motors, capable of running at low rpms with high torque, providing very low energy consumption, and the ability to process oversized tires with ease.

CM says this shredder has the ability to accept a modified version of its patented fixed rotor design with removable rotor technology, making it one of the most versatile machines in the industry. Units can be fitted with removable rotors equipped with CM-patented Holman knives for producing clean-cut TDF (tire-derived fuel) for the cement and energy industries. For other applications, one piece shear blades can be used to process contaminated tires or for preshredding when material size and exposed wire are not critical.

CM has also introduced its new “Secure Lock” system which increases clamping pressure to secure the knife group in the cutting box, increasing knife tolerances and resulting in cleaner cuts.

According to CM, the first Hybrid Shredder was tested and installed in 2013 in the U.S. and is being operated along with other CM equipment by a producer of refined rubber products used in commercial flooring, sport surfaces and sound insulation products. In this application, the CM Hybrid processes 100-percent truck and OTR tires into 4- to 6-inch pieces, ideal feedstock for the CM4R Liberator, which then cleanly removes the steel from the rubber fraction, creating clean, wire-free rubber. The crumb is then processed by a CM Dual Drive Crackermill yielding high quality fine powders.

CM says a second CM Hybrid Shredder was recently sold into France as part of a complete processing line to produce TDF for the cement industry. CM says they outfitted this shredder with a different knife configuration, utilizing a combination of CM knives and shear blades that will produce clean-cut feedstock for a second shredder, together generating impressive tonnage ranging from 12 to 14 tph of TDF.
