Q: What's the difference between linear combination weighers and multihead weighers?

A:

A multihead weigher typically features 10–24 weighing heads arranged in a circular layout, performing fully automated combination weighing at high speed. It's widely used in large-scale continuous packaging lines. In contrast, a linear combination weigher arranges fewer heads (e.g. 8–12) in a straight line, often incorporating some manual or semi-automatic steps. While both use combination calculation weighing, linear systems prioritize flexibility, gentler product handling, and cost-efficiency—making them better suited for smaller batches, irregular products, or operations where speed is not the top priority.
