The shredding technology is based on an extremely aggressive knife design and open cutting table. These distinct technical advantages ensure our shredders provide outstanding performance when dealing with mixed and challenging materials.

These key features also make Metso EtaPreShred units extremely resistant to wear caused by materials and waste normally considered as nonshreddable; including solid steel,  reinforced concrete and rocks.

Metso EtaPreShred units tackle most forms of waste – even the nonshreddable kind.

• Open cutting table reduces wear to the bare minimum
• Bi-directional shredding results in a consistent flow of shredded material onto down-stream conveyors
• Asynchronous shredding keeps waste constantly moving, thus improving shredding efficiency
• With our aggressive knife design, no pushing device is required
• Central lubricating system is standard on all machines
• Automatic reversal if knives encounter large or tough steel cement parts
• Intelligent shredding routines automatically adapt to processed material characteristics. The PLC control system is equipped with six standard programs, including two that can be individually programmed
• Hardox steel used in all parts of the cutting table exposed to wear
• Bi-directional shredding with equal speed and torque reduces wear and improves capability and pre-shredder capacity
