Q: Is more heads always better in a combination weigher? What determines the number of heads？

A:

A multi head combination weigher with more heads allows for more combination calculation weighing options, improving accuracy and efficiency. However, more heads don't always mean better performance. In a linear combination weigher, the number of heads is typically based on product type, target weight, required speed, and available space. Lightweight or irregular items may need more heads to ensure stable combine weigh in results. Cost and maintenance also rise with more heads. The best setup balances throughput, accuracy, and investment. Choosing between a combination scale with 10 or 14 heads—or more—should align with your specific needs.
