Global recycling rules are tightening fast. Extended producer responsibility (EPR) schemes, mandatory recycled-content targets and landfill bans on baled plastic film are pushing recyclers to process harder feedstock than ever: baled PET bottles, HDPE lumps from extruders, thick pipes, woven bags, cardboard bales and rubber offcuts. For most plants the bottleneck is no longer sorting — it is the first size-reduction step. That is exactly where the single shaft shredder has become the profit engine of the recycling line.
Three forces are reshaping demand in 2026:
A single shaft (one shaft) shredder feeds material against a rotating rotor with a hydraulic pusher and controls output size with a screen. Compared with a double shaft machine it gives a smaller, more uniform output — ideal as the first stage ahead of a granulator or washing line. The engineering points that decide your output and cost per ton:
| Design point | Why it matters |
|---|---|
| Symmetrical rotary knives | Each knife can be indexed four times before replacement, cutting blade cost per ton sharply |
| Hydraulic pusher, adjustable speed | Pressure and speed are set to the material load, so lumps and bales feed smoothly instead of stalling the rotor |
| Replaceable screens | Output from 20 mm upward — one machine can serve several downstream products |
| Automatic reverse clearing | Jam cleared in seconds without opening the chamber, protecting the operator and the knives |
| Hardened rotor and gearbox | Continuous multi-shift duty on tires, pipes and bales without shaft fatigue |
| Criteria | Single shaft shredder | Double shaft shredder |
|---|---|---|
| Output size | Uniform, screen-controlled (about 20–100 mm) | Coarse, tear-type |
| Best feed | Bales, lumps, pipes, film, woven bags, wood | Bulky mixed waste, tires, MSW |
| Downstream | Feeds granulator or washing line directly | Often needs a second stage |
| Energy per ton | Lower | Higher |
In a typical 2026 layout, a single shaft shredder with a 55 kW motor and 1,000 mm rotor handles roughly 1.5–3 t/h of baled film and about 2–4 t/h of PET bottle bales, depending on screen size. Because the knives are indexable, blade consumption usually falls to one or two sets per year in single-shift operation.
Hangzhou Joful Industry Co., Ltd. has manufactured shredders and stainless steel fabrication since 2009, exporting 40–50% of output to recyclers, compounders and waste contractors worldwide. Every single shaft shredder is 100% inspected before delivery, with 40 sets per month supply capacity and 7–48 working days lead time.
Talk to our engineers: send material photos, bale size and required output, and we will come back with a rotor and screen configuration plus a kWh-per-ton estimate within one working day.
