In a recent post, we walked through why belt speed alone doesn't tell you a sorter's throughput, and why carrier pitch matters just as much. This week, a real-world data point gives us a chance to go one level deeper, into the step that happens just before the sort: singulation. What singulation actually is Singulation is the process of taking parcels that arrive bunched, overlapping, or touching, and turning them into a single, evenly spaced stream before they reach a scanne

When courier and last mile operators evaluate sortation systems, belt speed is almost always the first number they ask about. It is intuitive. Faster belt means more parcels sorted per hour. It feels like the right question. It is not the complete question. Belt speed matters, but it only tells part of the story. The number that actually determines how much throughput a system can realistically deliver is the relationship between speed and carrier pitch — the distance between
