Quick answer
Multihead weighers combine several partial weights to reach a target quickly and can suit higher-speed piece or granule applications. Linear weighers feed one or more weigh hoppers sequentially and can suit lower speeds or simpler products. Product behaviour, target-to-piece ratio and damage risk determine the result.
Side-by-side comparison
| Decision factor | Multihead combination weighing | Linear weighing |
|---|---|---|
| Weighing principle | Combines several hopper weights to form a target | Coarse and fine feeds into one or more weigh hoppers |
| Output | High potential with enough combinations and stable feeding | Moderate, depending on lanes and target |
| Piece products | Strong for mixed piece weights and free-flowing products | Suitable where feed can be controlled predictably |
| Fine powders | Usually not first choice for dusty cohesive powder | Specialised linear/auger routes may be more suitable |
| Target weight | Needs enough pieces and combinations | Can suit wider targets with appropriate feed |
| Fragility | Multiple transfers and vibration require assessment | Simpler path may be gentler in some layouts |
| Footprint/height | Often taller with radial feeders and many heads | Can be simpler and narrower |
| Changeover | Many contact parts; tool-free design can help | Fewer lanes but feed settings still require proof |
Decision checks
- Piece-size and unit-weight distribution
- Flow, stickiness and fragility
- Target weight and allowed tolerance
- Required packs per minute
- Available headroom and discharge path
- Cleaning and allergen changeover
- Integration with pouch, VFFS or container line
How to prove the choice
Run a full representative product mix, not selected uniform pieces. Compare giveaway, misses, damage, blockages, changeover and sustained output through the downstream packer.
