| 2 shaft – Also Called Dual Shaft Shredder | 4 shaft – Also called Quad Shaft Shredder |
| Dual Shaft Shredders have two counter-rotating shafts with intertwined individual cutters mounted on each of them which rotate in opposite directions. This type of shredder is often used for VOLUME REDUCTION or PROCESSING OF RAW MATERIALS of bulky and light items like wooden pallets, drums, MSW, BMW, Organic waste RDF etc. | Quad shredders have 4 shafts with different design cutters which can be rotated in opposite directions to give more flexibility in shredding numerous objects and to bring them up again for a second pass to ensure correct sizing. They will grind the materials into small peices untill they are small enough to poass thru the seive underneath the shredding chamber. |
| Advantages: | Advantages: |
| Reduces volume by over 80% Can process the materials in just one rotation giving higher throughput Large-diameter cutters give faster cutting and have a longer life. High throughput Simple Construction Low operating and maintenance costs | Uniform sizing of materials Almost 90% volume reduction Can destroy any type of bulky material Secondary Shafts assist in shredding as well as sizing Sizing ranges from 25-70mm |
| Disadvantages: | Disadvantages: |
| Widely varying output sizes Pieces as well as strips Cannot produce a consistent particle size Mostly used as a primary shredder | Heavy and complex construction Higher cost as compared to the dual-shaft shredder Low throughput , takes more time to churn out the materials More maintenance required Higher power requirement as throughput is less. |
Difference between 2 shaft and 4 shaft shredder
IS ENORMOUS
not only in cost but also in the size and electric power
Difference between 2 shaft and 4 shaft shredder is primarily in the output size, the shredder should be choosen according to the purpose of shredding
If you want to just break it into pieces then the best option is the double shaft, this is the most common shredder.
If you want to shred the materials for further processing then the 4 shaft is a better option as it will give equal output size
