A new approach to optical sorting. Gravity Sorter is a free-fall AI optical sorter designed for accurate separation of fine and complex mixed material streams. The system tracks each object mid-air and ejects target materials with high precision, delivering stable sorting performance for recycling applications. The machine processes materials in the 4-70 mm range at up to 6 tons per hour, achieving 95%+ purity. Its compact belt-free design reduces mechanical complexity and supports efficient integration into existing lines.

AI sorting platform
The Gravity Sorter is controlled through the inSystem Cloud Platform™, accessible from any browser. The platform gives operators full control over the sorting process: configure input fractions, adjust ejection settings per material class, and monitor key statistics in real time. The interface is designed to be intuitive and requires no programming skills. A new operator can be trained
on the platform in 1 day.
AI training platform
The inSystem AI Training Platform™ includes a built-in image labelling tool. Operators can label sorting images directly in the interface, trigger AI retraining, and deploy trained models without external support at no extra cost. Retraining requires approximately 2,000 labelled images. This makes the system self-sufficient: the sorting accuracy improves over time as operators add more data from their specific material stream.

Design and construction
A new approach to optical sorting. The Gravity Sorter uses free-fall AI vision to identify and separate materials in the 2-50 mm range that conventional belt-fed sorters miss. The system captures 10 images of each object mid-air, tracking shape and trajectory before precision ejection through 2 mm nozzles into up to 3 output fractions.
At inSystem.io, we step in as an innovation partner for recycling facilities, helping improve efficiency and reduce labor costs. We also develop tailored solutions to fit each plant layout and operations.

Triangular conveyor
The optical sorter uses a triangular conveyor that improves material flow and separation efficiency.
As mixed material moves over the angled section, lighter items lift and slide upward while heavier ones remain on the belt, ensuring steady and precise separation.

FLOW OPTIMIZATION
Conveyor chain
Connecting multiple optical sorters in sequence maintains material flow and consistent throughput. This configuration supports continuous sorting and helps use space efficiently within the production line.
