SHAFT SHREDDER FOR CRUSHING LARGE PIECES

Double shaft shredders have two parallel shafts fitted with an array of cutters that rotate in opposite directions and intermesh. This allows for high throughput shredding.
An 800 double shaft shredder generally indicates the cutting chamber is 800mm wide. Common sizes range from 600-1200mm.
These industrial shredders are heavily constructed, often over 10 tons, to handle large pieces of dense materials. Common materials are plastics, wood, paper, tires, metals, and e-waste.
They are typically used as the initial coarse shredding step in a multi-stage size reduction process. The output is usually 50-300mm pieces.
An 800 shredder can typically process 5-50 tons per hour depending on the material and desired output size.
After coarse shredding, the material often goes through additional shredders, granulators, or grinders for fine crushing into powders or small granules under 10mm.
Key components of double shaft shredders are the cutters, shafts, bearings, drive system (electric or hydraulic), hopper, and discharge system. Proper maintenance is critical.
They are normally equipped with features for safety and noise/dust reduction. Explosion protection is critical when shredding combustible materials.
