Camera Options

Standard — Monochrome (B/W) line-scan

3 × 8,192 px cameras, detection down to 25 μm. Recommended for maximum detection sensitivity on natural pellets.

Optional — Color line-scan

3 × 4,096 px color cameras, detection down to 50 μm. Choose when color discrimination between defect types matters more than absolute resolution. All other specifications are identical.

What It Does

Pellets are fed from your pipeline (DN90) onto a vibration platform, then free-fall through the inspection zone where three opposed line-scan cameras capture every pellet. The software flags black specks, contaminated, and color-deviant pellets in real time — and the rejection unit ejects them instantly into a segregated defect stream. Clean pellets continue to your good-material silo. The whole line runs unattended, with live video, defect annotation, and statistics throughout.

Software Highlights

  • Unattended inline sorting, 24/7
  • Real-time video and defect labeling: type, size, area, shape, timestamp
  • Defect self-learning system; auto light-intensity control
  • Trend charts, histograms, size-class and defect-class statistics
  • Built-in database, multi-level permissions, customizable reports

Service & Warranty — Delivered by Gayan

  • Factory acceptance test with your pellets, video-documented before shipment

Prove it on your material first.

Send us a 25 kg sample. We'll run it on the GS-1000 Pro, and send back the video, the reject statistics, and the cleaned-pellet result. The first sample test is free.
