Spare Parts
Laboratory Test Sieves
Separate laboratory samples into measurable fractions with test sieves selected for the required particle-size range.

No quantitative check on a coarse or fine fraction
Weigh material retained on each sieve to describe the sample distribution.
Inconsistent batch acceptance
A defined aperture series gives incoming and finished samples the same basis for comparison.
Where It Fits in Your Plant
Sand and aggregate laboratories
Determine retained fractions using the aperture series and test procedure required for the material.
Powder and granule production
Check samples after grinding or screening. Frame fit, mesh condition and traceability belong to the actual sieve supplied; a product description does not establish calibration or certification.
How the Laboratory Test Sieves Work
A sieve frame holds a specified mesh or perforated surface. Stacked sieves retain successive fractions, which are weighed to establish the sample grading.
Selection Factors
- Aperture series: choose openings that resolve the required particle-size range.
- Frame compatibility: diameter and height must fit the shaker, lid, receiver and clamp.
- Traceability: required dimensional inspection or certification must refer to the actual sieve supplied.
Material & Process Compatibility
Granule samples
- Material form
- Dry granules
- Typical application
- Compare particle-size distribution between batches
- Handling considerations
- Sieve sequence and test mass
Powder samples
- Material form
- Dry dispersible powder
- Typical application
- Measure coarse fractions in a sample
- Handling considerations
- Method suitability for cohesive fines
Common Issues & Checks
- Inconsistent retained mass: inspect blinded openings and sample losses at frame joints.
- Damaged mesh: remove the sieve from comparative testing until its condition and opening dimensions are resolved.
Useful answers
Frequently asked questions
How is a particle-size distribution measured?
A representative sample passes through a selected sieve stack. The mass retained on each sieve and in the receiver is weighed and expressed as fractions of the recovered sample.
