PRI-MAX®

PR4200 Primary Reducer

SSI’s PRI-MAX® PR4200 is a heavy duty, low-speed, high-torque industrial primary shredder designed for high capacity volume reduction of the toughest materials considered by others to be “non-shreddable”.

SSI’s PRI-MAX® PR4200 primary reducer is more than a heavy duty shredder. It combines ripping and shearing technologies to shred, tear, pierce, chop, split, flatten, crush, break and reduce materials. The unique cutter profiles and patented open cutting table design are key to achieving high capacity reduction of virtually any material. With processing rates from 20 to 50 tons per hour, SSI’s PRI-MAX® PR4200 is one of the most comprehensive multi-material reducers in the world.
