Used 900-Type Plastic Shredders: A Practical Buyer’s Guide

The 900-type plastic shredder represents a popular mid-range industrial shredding solution, capable of processing 800-1,200 kg of plastic waste per hour. These robust machines feature a 900mm cutting chamber width, making them suitable for processing bulkier plastic items while maintaining relatively compact dimensions for factory installation.
