Stationary pre-shredders are heavy-duty pre-treatment units for mixed solid materials, including renovation debris from interior demolition or remodeling, bulky items, municipal refuse, and landfill stale material. They open plastic bags and woven sacks to then reduce large waste pieces before screening or separation. Twin shafts pull the feed into the shredding chamber, where high-torque rotation tears bags open and breaks down oversized items. Four-direction shaft rotation helps process soft and hard materials more evenly while reducing wrapping from flexible materials such as plastic bags, woven sacks, and textiles.

Main Components
Bag Opening Blades

Bag Opening Blades
Hardox 400 blades are used for tough mixed materials that may contain bags, textiles, wood, and bulky pieces. The double-sided cutting design works with the four-direction shaft rotation to open bags more evenly and reduce wrapping during operation.

Drive System

Drive System
The drive system uses splined shafts, hardened planetary reducers, and a rigid coupling structure to handle heavy loads and sudden impact during pre-shredding. It is built for continuous processing in demanding waste treatment conditions.
