Particle & solid-state
Sieve Shaker (Analytical Sieving)
Shakes a stack of test sieves so a powder or granule separates into size fractions. Weighing each sieve gives the particle size distribution by mass.

TROUBLESHOOTING
Common problems, causes and fixes
Mass balance poor (loss above limit)
Likely causes
- • Dust escaping
- • Material stuck in sieves
- • Weighing errors
What to do
- • Fit the lid and seals properly
- • Brush out sieves and re-weigh
- • Check balance and tare values
Results coarser than expected
Likely causes
- • Sieve blinding
- • Sieving time too short
- • Agglomerated or electrostatically charged powder
What to do
- • Clean sieves; use sieving aids if validated
- • Confirm the end-point
- • Condition the sample or use air-jet sieving
Results finer than expected
Likely causes
- • Torn or stretched mesh
- • Granule attrition during shaking
What to do
- • Inspect and replace damaged sieves
- • Reduce amplitude or time within validated limits
Shaker noisy or stack moving
Likely causes
- • Loose clamp
- • Worn rubber mounts
What to do
- • Tighten the clamp
- • Replace mounts
