Which one is better: a single-shaft plastic shredder or a double-shaft plastic shredder?
There is no absolute “better” one. The right choice depends mainly on the waste materials you need to process, the required output size, capacity, and the downstream recycling process.
Type | Better for | Main advantages |
Single-shaft plastic shredder | Plastic blocks, thick plastic pipes, rigid profiles, purgings, pre-sized hard plastics | More uniform output size, better control |
Double-shaft plastic shredder | Plastic drums, bulked PET bottles, bales, mixed or bulky plastic waste | Strong feeding ability, high capacity, ideal for primary shredding of bulky materials |
Simple selection guide
· Choose a single-shaft plastic shredder if your main materials are plastic blocks, thick plastic pipes, rigid plastics, and you need a more controlled, uniform output.
· Choose a double-shaft plastic shredder if your main materials are plastic drums, bulked PET bottles, large hollow items, bales, or mixed plastic waste.
· For many complete recycling lines, the best setup is a shredder for primary shredding + crusher or granulator for secondary crushing.
