Single-shaft shredding system

Single-shaft shredding systems can be almost universally used and are able to process a broad range of different materials. Depending on the model, they are equipped with a pusher system that drives the material against the rotor. Replaceable cutting inserts on the rotor shred the material, and an easily replaced screen controls the final particle size.
