Bag Splitter
Opens collection bags at a controlled rate without shredding what is inside — the recoverables arrive at the line intact and sortable.
The Sherbrooke OEM bag splitter position integrates a bag opener: a Hardox-protected slitting rotor working against a segmented comb with bolted knives opens collection bags at better than 95% opening rate, while a frequency-controlled discharge conveyor meters the released material to the line. The receiving hopper buffers collection-truck dumps (tens of cubic meters class), decoupling tipping from processing. Drive is twin rotor motors with a PLC-monitored safety package. Sherbrooke OEM engineers the position, structure, chutes, and plant-controls integration from Sherbrooke, Quebec.
Where It Fits
- Bagged single-stream and MSW programs where material arrives in collection bags
- Organics programs opening bags ahead of biological treatment
- Front ends that need tipping decoupled from steady line feed
Configuration & Options
Every unit is engineered per project — these are the configuration choices and options we quote against, not limits.
| Model class | Rotary bag splitter (SR IV class), segmented comb |
|---|---|
| Opening rate | Better than 95% |
| Feed capacity | Per project; engineering default around 25–30 t/h |
| Hopper | Buffer capacity on the order of 30 m³ — per collection pattern |
| Throughput control | Frequency-controlled discharge conveyor |
| Rotor protection | Hardox wear protection on the slitting rotor |
Construction
| Slitting rotor | SR-class rotor with Hardox protection |
|---|---|
| Comb | Segmented comb with bolted, individually replaceable knives and attenuator |
| Rotor drives | Twin geared drives |

| Structure & chutes | Receiving structure and chute work by Sherbrooke OEM |
Bag Splitter — Frequently Asked Questions
Why not just run bags through a shredder?
Because a shredder destroys the recoverables along with the bag — glass shatters into everything, containers shred into film-sized flakes the sorters cannot eject. A bag splitter slits the bag and lets gravity empty it: the contents arrive at the line whole, which is exactly what every downstream machine is designed to sort.
What happens to the bag film itself?
It travels the line as a film fraction — recovered by vacuum systems or optical sorters, or removed as residue, per the project flowsheet. Keeping bags whole rather than shredded makes that film capture dramatically easier.
How does the splitter smooth out collection-truck dumps?
The hopper takes the whole tip at once, and the frequency-controlled discharge conveyor meters material out at the line rate. Trucks stop waiting on the line, and the line stops seeing surges — the splitter doubles as the front-end metering device.
