How Multi-Head Weighers Work: The Complete Guide

Multi-head weighers, also called combination scales, have revolutionized weighing technology across industries – from food processing to hardware and chemical manufacturing. If you’re new to automated weighing systems, understanding how these precision instruments operate can help optimize your packaging line.

Core Working Principle

At its heart, a multi-head weigher uses advanced software algorithms to achieve perfect portion control. Here’s the step-by-step process:

1. Product Feeding

   • Bulk products enter through the infeed funnel via elevators/conveyors

   • The vibrating top cone and feeding tray distribute material evenly

2. Smart Distribution

   • Products move toward the edge via vibration

   • Special dimpled surfaces prevent sticking (ideal for sticky items like candy)

3. Precision Weighing

   • Each of the 10-24 weigh buckets contains an independent load cell

   • All buckets continuously weigh their contents during operation

4. Optimal Combination Selection

   • The computer analyzes all possible bucket combinations

   • Selects the group that sums closest to your target weight

   • Example: For 100g target, might combine buckets 1+3+10+12

5. Discharge & Repetition

   • Selected buckets discharge product into packaging

   • System immediately recalculates for next weighing cycle

Key Advantages of Combination Weighers

✔ Unmatched Speed – Processes up to 120 weighments/minute
✔ Precision Accuracy – Achieves ±0.01-0.02g consistency
✔ Product Protection – Gentle handling preserves fragile items
✔ Labor Savings – Replaces 4-6 manual operators
✔ Versatility – Handles products from 1g to 5kg

Choosing the Right Configuration

Pro Tip: Sticky products require special textured stainless steel buckets, while fragile items need vibration-adjustable systems.
