Can Single Color Sorter Handle Multiple Materials? Yes, a single color sorter can handle multiple materials, but its effectiveness depends on several factors, including the type of materials, their color differences, and the sorter's technology. Here’s how it works:   1. How a Color Sorter Handles Multiple Materials Color sorter machines use optical sensors (CCD cameras, or near-infrared  camera) to detect differences in:   - Color (RGB, grayscale)   - Reflectance (how light bounces off the material)   - Shape/Size(if combined with AI vision)     If the materials have distinct color differences, the sorter can separate them by programming different rejection criteria.   Examples:   ✔ Plastic Recycling: Sorting PET (clear/blue) or HDPE (white/black/red/blue/yellow).   ✔ Food Processing: Separating green vs. black coffee beans, or defective grains.   ✔ Mining/Ore Sorting: Differentiating colored minerals (e.g., quartz vs. feldspar).      2. Limitations & Challenges - Similar Colors: If two materials look alike (e.g., white PVC and white PET), a basic color sorter may struggle.   - Surface Texture: Glossy vs. matte finishes can affect accuracy.   - Speed vs. Accuracy: More materials = slower sorting or higher error rates.      3. Solutions for Sorting Multiple Materials   - Multi-Spectral Sorting: Uses NIR + RGB cameras to detect chemical composition (e.g., different plastics).   AI + Machine Vision: Trains the sorter to recognize subtle differences beyond color.     4.Cases of Multi-Function Sorting Effect Demonstration
