Sieve Particles
Separate particles by size or measure a particle-size distribution using a controlles stack of test sieves.
- Quality-control testing
- Particle-size distribution
- Wet or dry sieving
- Fine-powder analysis
Evaluate Sieving Equipment >
Separate a Product Fraction
Remove oversized material, recover a target fraction, classify material, or prepare feed for the next process step.
- Scalping and de-dusting
- Fraction recovery
- Product cleanup
- Process classification
Explore Separation Options >
Create a Representative Sample
Divide bulk samples into smaller portions while preserving the original particle size and composition distribution.
- Laboratory sample preparation
- Quality control retention samples
- Reduce operator bias
- Consistent downstream testing

HOW THE PROCESS WORKS
Controlled motion. Defined openings. Repeatable results.
The equipment applies a controlled motion or air stream so particles encounter openings or dividing paths in a consistent, reproducible way.
Load the Material
Introduce a known sample mass or controlled product stream.
Apply Controlled Motion
Vibration, tapping, air flow, or rotary division moves particles.
Separate or Divide
Particles pass through defined openings or distribution paths.
Measure or Collect
Weigh fractions, recover a target cut, or collect sub-samples.
EQUIPMENT FAMILIES
Choose the technology that matches the material and method.
Selection depends on particle behavior, sample quantity, target size range, required standards, and whether the goal is analysis, separation, or sampling.
Sieve Shakers
Controlled vibratory, tapping, and specialty motions for reproducible particle-size analysis.
