New Shredders Offer Size Reduction in a Small Footprint

Conair has introduced its GP series shredders for processors who need to reduce hard scrap too large for a granulator, but do not need the high throughput or cost of a larger shredding machine. The GP 924 features a 24-inch cutting chamber. The GP 935  features a 35-inch chamber.

A single 8.7-inch diameter steel rotor cuts against a fixed blade knife, both of which are drop-forged from 4140 high-alloy steel for maximum durability. Both the rotor knife blades and fixed blade can be rotated to extend service time between sharpening.

The rotor is powered by a high-efficiency 25 hp or 40 hp AC motor, coupled through a large belt drive to an oversized, heavy-duty gearbox. These drivetrains, housed in the base of the shredder, produce high cutting torque at relatively low rotor RPM to reduce thick scrap with limited noise.

The shredders offer a large, open-top infeed hopper, capable of accepting gaylord-sized batch feeds. A hydraulic ram drives scrap into the cutting chamber. Top and side scrapers clean and shield the ram face, preventing shredded material from entering and interfering with the ram mechanism.

Shredder operation is controlled through a programmable logic controller. Onboard alarms alert operators to changing operational conditions, and electromechanical safeties disable operation during maintenance access.
